DOI: 10.3897/zookeys.1195.112328

Authors: Rafał Gosik, Roberto Caldara, Ivo Toševski, Jiří Skuhrovec

Abstract: The mature larvae of the following fourteen Rhinusa species are described and illustrated: Rhinusa antirrhini (Paykull, 1800), R. asellus (Gravenhorst, 1807), R. collina (Gyllenhal, 1813), R. eversmanni (Rosenschoeld, 1838), R. florum (Rubsaamen, 1895), R. herbarum (H. Brisout de Barneville, 1862), R. incana (Kirsch, 1881), R. linariae (Panzer, 1796), R. melas (Boheman, 1838), R. neta (Germar, 1821), R. pilosa (Gyllenhal, 1838), R. rara Toševski & Caldara, 2015, R. tetra (Fabricius, 1792), and R. vestita (Germar, 1821). The pupae of thirteen of them (except R. incana) were also described. The comparison of larval morphological characters and plant preferences provides evidence supporting the existence of different species groups previously established according to a phylogenetic analysis based on adult morphological characters. The following diagnostic attributes distinguishing the genus Rhinusa are highlighted. For the larvae: (1) pronotal shield indistinct; (2) thoracic prodorsal fold small or even vestigial; (3) abdominal postdorsal folds (especially of segments III–VII) high or even in the form of conical protuberances; (4) cuticle of abdominal segments densely covered with asperities; (5) cuticle without dark spots or dark pigmentation; (6) head suboval, rarely round; (7) labrum usually with 2 als; (8) des1 short or absent, rarely elongated; and (9) fs1-3 usually absent or minute. For the pupae: (1) body stout; (2) head protuberances always present; (3) pronotal protuberances (if present), separated at bases of the pronotum, always wider than higher; (4) abdominal protuberance usually present, wide or round; (5) femora usually with a single fes; and (6) urogomphi short or vestigial. Keys to the larvae and pupae described here are provided. All the characters used for identification are illustrated by photographs or drawings. Biological and distribution data, including new information, are provided for all the species studied.

New species in the genera Eumacrocyrtus Schultze, 1923 and Enoplocyrtus Yoshitake, 2017 from Luzon Island, Philippines (Coleoptera, Curculionidae, Entiminae, Pachyrhynchini) https://zookeys.pensoft.net/article/110217/ ZooKeys 1191: 23-33

DOI: 10.3897/zookeys.1191.110217

Authors: Analyn A. Cabras, Perry Archival C. Buenavente, Milton Norman Medina

Abstract: We describe and illustrate two new species from two previously monotypic genera Eumacrocyrtus Schultze, 1923 and Enoplocyrtus Yoshitake, 2017 from Luzon Island, Philippines: Eumacrocyrtus robertfoxi sp. nov., and Enoplocyrtus angelalcalai sp. nov. Eumacrocyrtus robertfoxi sp. nov. serves as a new record for Luzon Island for Eumacrocyrtus which was only previously represented by E. canlaonensis Schultze, 1923 from Negros Island whereas Enoplocyrtus angelalcalai sp. nov. serves as an additional record of Enoplocyrtus in Mountain Province in Luzon Island. The discovery of these two new species from the Zoological Collections of the Philippine National Museum, collected in 1947 and 1985, respectively, highlights the value of natural history collections for the present and future generations of researchers.

Taxonomic reappraisal of the European fauna of the bark beetle genus Cryphalus (Coleoptera, Curculionidae, Scolytinae) https://zookeys.pensoft.net/article/101388/ ZooKeys 1179: 63-105

DOI: 10.3897/zookeys.1179.101388

Authors: Mathias Just Justesen, Aslak Kappel Hansen, Miloš Knížek, Åke Lindelow, Alexey Solodovnikov, Hans Peter Ravn

Abstract: Species in the genus Cryphalus are small and notoriously difficult to identify. Even among the relatively well studied European species, erroneous identifications are evident from literature and in museum collections. These misidentifications relate to the small size and similar appearance of Cryphalus species but they are also a product of insufficient diagnostic characters. This is especially unfortunate since some European species are considered pests. Based on the study of more than 1000 specimens and a thorough literature review, robust morphological and molecular evidence supporting all five hitherto recognised native species of Cryphalus in Europe is provided. A key for the reliable identification of these repetition species including new diagnostic characters recognised for the first time, including those from male genitalia, has been constructed. Each native species is provided with a detailed morphological description and their economic significance, distribution, and ecology discussed. Significant genetic variability is observed between certain clusters that should be further explored in a broader geographic context. Lastly, the need for a taxonomic revision of the genus Cryphalus for the entire Palearctic region due to the presence of many similar looking species which are often confused, thus distorting the knowledge of each species is highlighted.

New records of Curculionoidea from Newfoundland and Labrador, with the first records of Orthochaetes setiger ([Beck]) (Curculionidae, Curculioninae, Styphlini) for North America https://zookeys.pensoft.net/article/91567/ ZooKeys 1136: 125-162

DOI: 10.3897/zookeys.1136.91567

Authors: David W. Langor, Robert S. Anderson, Patrice Bouchard, Stephen D. Langor

Abstract: Thirty species of Curculionoidea (28 Curculionidae and one each of Brentidae and Nemonychidae) are reported as new records from the Canadian province of Newfoundland and Labrador, most of them from the island of Newfoundland. As well, 13 species of Curculionidae and one of Brentidae previously recorded from Newfoundland are newly reported from Labrador, and one Curculionidae previously recorded from Labrador is newly reported from Newfoundland. The Palearctic species, Orthochaetes setiger ([Beck]), is herein reported as a new Canadian and North American record, with specimens documented from Newfoundland and British Columbia. Additions to the primary key for North American weevils are provided to help identify this genus among the North American fauna. Of the species of Curculionoidea previously recorded from the province in published literature, there is uncertain evidence for the occurrence of 14 species in the province as a whole or in the Labrador portion. Seven species are hereby removed from the faunal list for the province. One of those, Trachodes hispidus (Linnaeus), is also removed from the Canadian faunal list. The 134 species of Curculionoidea recorded from NL are listed and a brief synopsis of the fauna provided.

A revision of the North American genus Proctorus (Coleoptera, Curculionidae, Ellescini) with descriptions of two new species https://zookeys.pensoft.net/article/90392/ ZooKeys 1131: 135-153

DOI: 10.3897/zookeys.1131.90392

Authors: Jake H. Lewis, Robert S. Anderson

Abstract: The rarely collected North American endemic genus Proctorus (Coleoptera, Curculionidae, Ellescini) has hitherto contained two described species, P. armatus LeConte, 1876 and P. decipiens (LeConte, 1876). Here, Proctorus is revised and two new species, namely P. emarginatus sp. nov. and P. truncatus sp. nov., are described. Lectotypes for P. armatus and P. decipiens are designated from known syntypes. All four species in the genus are associated with Salicaceae, but, in addition to differences in external and genital morphology, there is also evidence of differing host plant usage between the species. A photographic key to the four species is provided to facilitate identification.

Nine new species of Trigonopterus Fauvel (Coleoptera, Curculionidae) from Sundaland https://zookeys.pensoft.net/article/89318/ ZooKeys 1124: 109-130

DOI: 10.3897/zookeys.1124.89318

Authors: Alexander Riedel

Abstract: The DNA of Trigonopterus specimens from the Sundaland region stored between ten and 32 years in museums could be used for next-generation sequencing. The availability of their cox1 sequence allowed the description of the following nine new species: Trigonopterus grimmi sp. nov., T. johorensis sp. nov., T. lambirensis sp. nov., T. linauensis sp. nov., T. microreticulatus Riedel, Trnka & Wahab sp. nov., T. mulensis sp. nov., T. sarawakensis sp. nov., T. siamensis sp. nov., and T. singaporensis sp. nov. The alternative original spelling of the name T. tounensis Narakusumo & Riedel is chosen to prevail over T. tounaensis Narakusumo & Riedel. The new species represent the first country records of Trigonopterus for Brunei, Singapore, and Thailand. Thus, the genus´ known area of distribution in the Sundaland region is significantly extended. A key and a catalogue are provided to the Trigonopterus species from Borneo, W-Malaysia, Singapore, and Thailand.

Morphology of immature stages, biology, and systematic position of the Violet seed weevil, Orobitis cyanea (Linnaeus, 1758) (Curculionidae, Conoderinae, Orobitiditae, Orobitidini) https://zookeys.pensoft.net/article/86888/ ZooKeys 1121: 59-82

DOI: 10.3897/zookeys.1121.86888

Authors: Rafał Gosik, Peter Sprick

Abstract: The mature larva of the weevil species Orobitis cyanea (Linnaeus, 1758), one of only two Palaearctic members of the supertribe Orobitiditae, is re-described, while the pupa is described for the first time. The biology of this species was studied at two sites in Germany. It was reared from seed capsules of Viola canina L. (Violaceae), and feeding holes were observed on V. riviniana Rchb. Adults of Orobitis cyanea and O. nigrina Reitter, 1885, specialists of Viola, show a well-developed escape mechanism, to which contribute a smooth surface, a rounded, nearly spherical body shape, and a seed-imitating thanatosis behaviour. The molytine weevil Leiosoma cribrum (Gyllenhal, 1834), the only other known weevil specialist of Viola in Europe, has a smooth surface, also, and is the most spherical species of the genus. The unique characters of the larva and pupa of Orobitis cyanea are discussed in regard to the systematic position of this taxon.

Description of immature stages of Gymnetron species (Coleoptera, Curculionidae, Curculioninae), with particular emphasis on the diagnostic morphological characters at the generic and specific levels https://zookeys.pensoft.net/article/78741/ ZooKeys 1090: 45-84

DOI: 10.3897/zookeys.1090.78741

Authors: Jiří Skuhrovec, Rafał Gosik, Roberto Caldara, Ivo Toševski, Aleksandra Batyra

Abstract: The immature stages of the following five Palaearctic Gymnetron species are described for the first time: G. tibiellum Desbrochers des Loges, 1900, G. veronicae (Germar, 1821), G. rotundicolle Gyllenhal, 1838, G. melanarium (Germar, 1821), and G. villosulum Gyllenhal, 1838. These species belong to four different groups previously established according to a phylogenetic analysis: the first two belong to the G. veronicae group and the other three to groups respectively bearing their name (G. rotundicolle, G. melanarium, and G. villosulum groups). All these species exhibit several diagnostic characters distinguishing them from each other. Some characters that can be used to separate Gymnetron from other genera in the tribe are also suggested. Three highly significant characters for the larvae and three for the pupae were identified. For the larvae they are: (1) labial palpi with single palpomeres, (2) all spiracles unicameral, and (3) epipharynx with a single pair of mes or none at all. For the pupae they are: (1) the pronotum with prominent pronotal protuberances, (2) abdominal segment VIII with a conical abdominal protuberance dorsally, and (3) very short or even reduced urogomphi. The species studied here are compared with those Gymnetron species already known and with other genera in the tribe Mecinini. Keys to the larvae and pupae described here are provided. All the characters used for identification are illustrated by photographs or drawings.

Species-rich bark and ambrosia beetle fauna (Coleoptera, Curculionidae, Scolytinae) of the Ecuadorian Amazonian Forest Canopy https://zookeys.pensoft.net/article/57849/ ZooKeys 1044: 797-813

DOI: 10.3897/zookeys.1044.57849

Authors: Stephanie A. Dole, Jiri Hulcr, Anthony I. Cognato

Abstract: Canopy fogging was used to sample the diversity of bark and ambrosia beetles (Coleoptera, Curculionidae, Scolytinae) at two western Amazonian rainforest sites in Ecuador. Sampling was conducted by Dr Terry Erwin and assistants from 1994–2006 and yielded 1158 samples containing 2500 scolytine specimens representing more than 400 morphospecies. Here, we analyze a subset of these data representing two ecological groups: true bark beetles (52 morphospecies) and ambrosia beetles (69 morphospecies). A high percentage of these taxa occurred as singletons and doubletons and their species accumulation curves did not reach an asymptote. Diversity estimates placed the total scolytine species richness for this taxon subset present at the two sites between 260 and 323 species. The α-diversity was remarkably high at each site, while the apparently high β-diversity was an artifact of undersampling, as shown by a Monte Carlo resampling analysis. This study demonstrates the utility of canopy fogging for the discovery of new scolytine taxa and for approximate diversity assessment, but a substantially greater sampling effort would be needed for conclusive alpha as well as beta diversity estimates.

Two new species of the genus Metapocyrtus Heller, 1912 (Coleoptera, Curculionidae, Entiminae, Pachyrhynchini), subgenus Orthocyrtus Heller, 1912, from Mindanao Island, Philippines https://zookeys.pensoft.net/article/63023/ ZooKeys 1029: 139-154

DOI: 10.3897/zookeys.1029.63023

Authors: Analyn A. Cabras, Milton Norman Medina, Maurizio Bollino

Abstract: Two new species of Metapocyrtus Heller, 1912, subgenus Orthocyrtus Heller, 1912 (Coleoptera, Curculionidae, Entiminae, Pachyrhynchini) are described and illustrated from Mindanao Island, Philippines. The species are Metapocyrtus (Orthocyrtus) davaoensis sp. nov. and Metapocyrtus (Orthocyrtus) hirakui sp. nov. from Davao City and Bukidnon, respectively. Brief bionomical notes and phenotypic characters compared to their sympatric Entiminae counterparts are also reported. The discovery of M. (O.) davaoensis sp. nov. in Davao City confirms how understudied Coleoptera are in Mindanao and underlines the potential for the discovery of new species even in highly urbanized areas.

Immature stages of Palearctic Mecinus species (Coleoptera, Curculionidae, Curculioninae): morphological characters diagnostic at genus and species levels https://zookeys.pensoft.net/article/50612/ ZooKeys 939: 87-165

DOI: 10.3897/zookeys.939.50612

Authors: Rafał Gosik, Jiří Skuhrovec, Roberto Caldara, Ivo Toševski

Abstract: The immature stages of ten Mecinus species are described for the first time and those of two other species are redescribed, adding important chaetotaxy characters that were missing from previous descriptions. These species belong to six of the nine assemblages of Mecinus species previously established according to a phylogenetic analysis. All these groupings are confirmed on the basis of several characters of mature larvae and pupae. Moreover, all the species show several characters that are useful for distinguishing them from each other, including cryptic species that previously had few differential characters. Some characters that may be useful for separating Mecinus from other genera in the tribe are suggested. To confirm the taxonomic identification of some larvae, the mtCOII gene was obtained and compared with sequences from identified adult specimens. The most important characters for separating the immature stages of the genera and species groups in Mecinus are the number of palpomeres of the labial palpi (1 or 2), the number of air tubes of the thoracic and abdominal spiracles (unicameral or bicameral), and the number of epipharyngeal setae. The species studied herein were compared with those known from other genera in the tribe Mecinini. Two keys, one to the described larvae and the other to the pupae, are provided. Detailed biological data, several of which are new, on some species are reported.

The morphology of the immature stages of Squamapion atomarium (Kirby, 1808) (Coleoptera, Brentidae) and notes on its life cycle https://zookeys.pensoft.net/article/36027/ ZooKeys 892: 143-160

DOI: 10.3897/zookeys.892.36027

Authors: Krzysztof Pawlęga, Jacek Łętowski, Ewelina Szwaj, Tomasz Gosławski

Abstract: The immature stages (egg, mature larva and pupa) of Squamapion atomarium (Kirby, 1808), as well as its development cycle and the phenology of its developmental stages, are described for the first time. The larva and pupa of S. atomarium have typical morphological features of the subfamily Apioninae. Morphological data on the immature stages were compared with the only fully described Squamapion species, S. elongatum (Germar, 1817). The larvae of the two species differ in body size and shape, head shape, setae length, the chaetotaxy of the mouthparts, and individual types of setae on the pronotum and thorax. In the case of the pupa, there are also differences in body size and in the type of setae and chaetotaxy of the head, pronotum, metanotum and abdomen.

Seven new species of Trigonopterus Fauvel (Coleoptera, Curculionidae) from the Tanimbar Archipelago https://zookeys.pensoft.net/article/38642/ ZooKeys 888: 75-93

DOI: 10.3897/zookeys.888.38642

Authors: Raden Pramesa Narakusumo, Michael Balke, Alexander Riedel

Abstract: Based on recent fieldwork, the hyperdiverse weevil genus Trigonopterus Fauvel is recorded for the first time from the Indonesian Tanimbar Archipelago, halfway between Australia and Western New Guinea. All seven species discovered on Tanimbar are new to science, and described here: Trigonopterus atuf sp. nov., T. kumbang sp. nov., T. laratensis sp. nov., T. porg sp. nov., T. selaruensis sp. nov., T. tanimbarensis sp. nov., and T. triradiatus sp. nov. The new species are authored by the taxonomists-in-charge, Raden Pramesa Narakusumo and Alexander Riedel. This fauna appears discordant and established by relatively recent dispersal from New Guinea and other Moluccan islands.

Rainforest and cloud forest Scolytodes (Curculionidae, Scolytinae, Hexacolini) from the Arthropods of La Selva inventory in Costa Rica: new species, new synonymy, new records https://zookeys.pensoft.net/article/33183/ ZooKeys 863: 1-34

DOI: 10.3897/zookeys.863.33183

Authors: Bjarte H. Jordal, Lawrence R. Kirkendall

Abstract: Quantitative collecting efforts over the last several decades in Costa Rica have resulted in many new species of insects. The Arthropods of La Selva projects included collecting from a typical lowland Neotropical forest and up an altitudinal transect, and has provided many valuable samples of insects, spiders and mites potentially new to science. We describe 18 new species in the bark beetle genus Scolytodes Ferrari, 1867, 14 of which were collected during this project: S. angulus Jordal & Kirkendall, sp. nov., S. sufflatus Jordal & Kirkendall, sp. nov., S. squamatifrons Jordal & Kirkendall, sp. nov., S. comosus Jordal & Kirkendall, sp. nov., S. spatulatus Jordal & Kirkendall, sp. nov., S. seriatus Jordal & Kirkendall, sp. nov., S. profundus Jordal & Kirkendall, sp. nov., S. catinus Jordal & Kirkendall, sp. nov., S. fimbriatus Jordal & Kirkendall, sp. nov., S. sulcifrons Jordal & Kirkendall, sp. nov., S. planifrons Jordal & Kirkendall, sp. nov., S. porosus Jordal & Kirkendall, sp. nov., S. mundus Jordal & Kirkendall, sp. nov., S. callosus Jordal & Kirkendall, sp. nov., S. parvipilus Jordal & Kirkendall, sp. nov., S. plenus Jordal & Kirkendall, sp. nov., S. niger Jordal & Kirkendall, sp. nov., and S. simplex Jordal & Kirkendall, sp. nov. One species, Scolytodes minutissimus Schedl, 1952, is redescribed to match the holotype. We give new Costa Rica records for S. costabilis Wood, 1974, which is the correct name for S. obesus Wood, 1975 (syn. nov.). We report Costa Rica as a new country record for six species: Scolytodes clusiacolens Wood, 1967, S. crinalis Wood, 1978, S. culcitatus (Blandford, 1897), S. libidus Wood, 1978, S. reticulatus (Wood, 1961), and S. spadix (Blackman, 1943). From a closely related genus, we provide the first record for Central America (and only the second collection) of Pycnarthrum fulgidum Wood, 1977.

One hundred and three new species of Trigonopterus weevils from Sulawesi https://zookeys.pensoft.net/article/32200/ ZooKeys 828: 1-153

DOI: 10.3897/zookeys.828.32200

Authors: Alexander Riedel, Raden Pramesa Narakusumo

Abstract: The genus Trigonopterus Fauvel, 1862 is highly diverse in Melanesia, the Moluccas, and the Sunda Islands. Only one species, Trigonopterus fulvicornis (Pascoe, 1885) was so far recorded from Sulawesi. Based on focused field-work the fauna from Sulawesi and nearby islands is here revised. We redescribe T. allotopus Riedel newly recorded for Sulawesi and describe an additional 103 new species: T. abnormis sp. n., T. adspersus sp. n., T. ambangensis sp. n., T. ampanensis sp. n., T. analis sp. n., T. arachnobas sp. n., T. armipes sp. n., T. artemis sp. n., T. asterix sp. n., T. barbipes sp. n., T. bonthainensis sp. n., T. carinirostris sp. n., T. castaneipennis sp. n., T. celebensis sp. n., T. cirripes sp. n., T. collaris sp. n., T. costatulus sp. n., T. curvipes sp. n., T. crenulatus sp. n., T. cricki sp. n., T. darwini sp. n., T. ejaculatorius sp. n., T. fuscipes sp. n., T. gracilipes sp. n., T. heberti sp. n., T. hirsutus sp. n., T. humilis sp. n., T. hypocrita sp. n., T. idefix sp. n., T. impressicollis sp. n., T. incendium sp. n., T. incognitus sp. n., T. indigenus sp. n., T. inhonestus sp. n., T. invalidus sp. n., T. jasminae sp. n., T. klabatensis sp. n., T. kolakensis sp. n., T. kotamobagensis sp. n., T. laevigatus sp. n., T. lampros sp. n., T. latipennis sp. n., T. lompobattangensis sp. n., T. luwukensis sp. n., T. mahawuensis sp. n., T. manadensis sp. n., T. mangkutanensis sp. n., T. matalibaruensis sp. n., T. mesai sp. n., T. minahassae sp. n., T. moatensis sp. n., T. modoindingensis sp. n., T. nanus sp. n., T. nitidulus sp. n., T. obelix sp. n., T. ovalipunctatus sp. n., T. ovatulus sp. n., T. pagaranganensis sp. n., T. palopensis sp. n., T. paracollaris sp. n., T. pauper sp. n., T. pendolensis sp. n., T. posoensis sp. n., T. prismae sp. n., T. procurtus sp. n., T. pseudallotopus sp. n., T. pseudanalis, sp. n., T. pseudovatulus sp. n., T. pseudovalipunctatus sp. n., T. pseudofulvicornis sp. n., T. pseudomanadensis sp. n., T. pseudosimulans sp. n., T. pumilus sp. n., T. rantepao sp. n., T. reticulatus sp. n., T. rhombiformis sp. n., T. rotundatus sp. n., T. rotundulus sp. n., T. rudis sp. n., T. rufipes sp. n., T. sampunensis sp. n., T. sampuragensis sp. n., T. satyrus sp. n., T. scabripes sp. n., T. scaphiformis sp. n., T. scitulus sp. n., T. selayarensis sp. n., T. serripes sp. n., T. seticnemis sp. n., T. silvicola sp. n., T. squalidulus sp. n., T. sulawesiensis sp. n., T. suturatus sp. n., T. tatorensis sp. n., T. tenuipes sp. n., T. tomohonensis sp. n., T. toraja sp. n., T. vicinus sp. n., T. viduus sp. n., T. volcanorum sp. n., T. wangiwangiensis sp. n., T. watsoni sp. n., and T. yoda sp. n.

Descriptions of immature stages of four species of the genera Graptus, Peritelus, Philopedon, and Tanymecus and larval instar determination in Tanymecus (Coleoptera, Curculionidae, Entiminae) https://zookeys.pensoft.net/article/30336/ ZooKeys 813: 111-150

DOI: 10.3897/zookeys.813.30336

Authors: Rafał Gosik, Peter Sprick, Michael G. Morris

Abstract: The mature larva and pupa of Graptus triguttatus triguttatus and the mature larva of Peritelus sphaeroides are described for the first time. The larvae of Philopedon plagiatum and Tanymecus palliatus are re-described. Five larval instars were determined in Tanymecus, thereby correcting doubtful data in the literature. The relationship between larval growth, number of larval instars, head width of the mature larva, and the adult weevil is explained using the example of Tanymecus. The nearly constant ratio of subsequent larval instars in head width ratio, termed “growth factor” and derived from Dyar’s ratio, is used for the determination of larval instars. Larval collecting and breeding data are discussed in relation to their significance for the clarification of life-cycles.

Morphological characters of immature stages of Palaearctic species of Cleopomiarus and Miarus and their systematic value in Mecinini (Coleoptera, Curculionidae, Curculioninae) https://zookeys.pensoft.net/article/28172/ ZooKeys 808: 23-92

DOI: 10.3897/zookeys.808.28172

Authors: Jiří Skuhrovec, Rafał Gosik, Roberto Caldara, Ivo Toševski, Jacek Łętowski, Ewelina Szwaj

Abstract: The relationship between the genera Cleopomiarus and Miarus of Mecinini (Curculionidae, Curculioninae) was tested on the basis of morphological characters from the immature stages. The mature larvae of five Cleopomiarus species (C. distinctus (Boheman, 1845), C. graminis (Gyllenhal, 1813), C. longirostris (Gyllenhal, 1838), C. medius (Desbrochers des Loges, 1893), and C. meridionalis (H. Brisout de Barneville, 1863)), three Miarus species (M. abnormis Solari, 1947, M. ajugae (Herbst, 1795), and M. campanulae (Linnaeus, 1767)), and the pupae of four Cleopomiarus species (C. distinctus, C. graminis, C. longirostris, and C. medius) and two Miarus species (M. abnormis and M. ajugae) are described in detail for the first time. To confirm the taxonomic identification of some larvae, DNA COI barcode was obtained and compared with those of adults. The immature stages of the species herein studied were compared with those known from other genera in tribe Mecinini. It is suggested that Miarus and Cleopomiarus may be monophyletic based on several shared distinctive characters. Larvae of Miarus have a characteristic maxillary mala with six finger-like dms of two sizes (one or two dms very long and the rest of medium length), this feature being apparently unique among weevils. Other genus-specific character states are observed in the pupae, such as the length of setae on the head, rostrum and pronotum, including the number of rs on the rostrum, ds on pronotum, and finally the shape of the urogomphi. A key to the described larvae and pupae were respectively presented. New biological and distributional data on some species are reported.

The morphology of the preimaginal stages of Cleopomiarus micros (Germar, 1821) (Curculionidae, Coleoptera) and notes on its biology https://zookeys.pensoft.net/article/27173/ ZooKeys 798: 45-62

DOI: 10.3897/zookeys.798.27173

Authors: Ewelina Szwaj, Jacek Łętowski, Krzysztof Pawlęga

Abstract: As yet little is known of the bionomics of weevils of the genus Cleopomiarus Pierce, 1919; current knowledge is limited to data on the morphology and biology of the preimaginal stages of certain species. This paper includes original information on the life cycle of Cleopomiarus micros (Germar, 1821). It presents the morphology of the egg, last larva (L3) and pupa. Data on the host plant (Jasione montana L.) and breeding plant (Campanula patula L.) and on the oviposition and phenology of the species are updated. The anatomy of the third-stage larva of C. micros shares certain traits with other species of the tribe Mecinini Gistel, 1848. Comparison of the morphology of preimaginal stages of C. micros with those previously described for other species of the genera Cleopomiarus and Miarus Schönherr, 1826 – previously considered the same genus – reveals species differences in larval body length, colour of the body and epicranium, and chaetotaxy of head and body.

DOI: 10.3897/zookeys.785.26674

Authors: Robert S. Anderson

Abstract: The new genus Purealus Anderson (type species, Purealus beckelorum gen n. et sp. n., type locality: McKenzie Lake, Gaines County, Texas) is described to accommodate a new species of cleonine weevil from western Texas and eastern New Mexico. Habitus images and images of taxonomically significant structures are presented. Purealus appears to be unique within Cleonini in the distinctly tumescent and asperate base of elytral interval 3, and widely separated procoxae, two characters apparently not shared with any other world Cleonini. The species cannot be placed in either Apleurus or Scaphomorphus due to a combination of characters in part shared by each genus and the lack of characters used to define the monophyly of each genus. Coding of the character states and addition to the analysis presented in a recent comprehensive analysis of world Cleonini did not provide any significant information on phylogenetic affinities. No information on plant associations is available; most specimens have been collected walking on the ground in winter months in arid habitats.

North American Xyleborini north of Mexico: a review and key to genera and species (Coleoptera, Curculionidae, Scolytinae) https://zookeys.pensoft.net/article/24697/ ZooKeys 768: 19-68

DOI: 10.3897/zookeys.768.24697

Authors: Demian F. Gomez, Robert J. Rabaglia, Katherine E. O. Fairbanks, Jiri Hulcr

Abstract: Bark and ambrosia beetles (Scolytinae) are the most successful group of invasive wood borers worldwide, and the most invasive among them are species in the tribe Xyleborini. This haplodiploid, highly inbred, fungus-farming group is represented by 30 non-native species in North America, of which at least five are serious pests. The few identification resources for Xyleborini that exist are becoming outdated due to new species arrivals and nomenclatural changes. Here we present a new comprehensive key to Xyleborini currently known from the continental United States. Compared to the previous key, the following species have been added to the North American fauna: Ambrosiodmus minor (Stebbing), Ambrosiophilus nodulosus (Eggers), Anisandrus maiche Kurentsov, Coptoborus pseudotenuis (Schedl), Cyclorhipidion fukiense (Eggers), Dryocoetoides reticulatus Atkinson, Dryoxylon onoharaense (Murayama), Euwallacea interjectus (Blandford), Xyleborinus andrewesi (Blandford), Xyleborinus artestriatus (Eichhoff), Xyleborinus octiesdentatus (Murayama), Xyleborus bispinatus Eichhoff, Xyleborus seriatus Blandford, Xyleborus spinulosus Blandford, and Xylosandrus amputatus (Blandford).

The smallest known species of Afrotropical Scolytoplatypus Schaufuss (Curculionidae, Scolytinae) – with unique features and an isolated phylogenetic position https://zookeys.pensoft.net/article/24199/ ZooKeys 749: 125-130

DOI: 10.3897/zookeys.749.24199

Authors: Bjarte H. Jordal

Abstract: Recent flight intercept trapping in Gabon provided four female specimens of a new species of Scolytoplatypus Schaufuss with several unusual features. It is the smallest known Afrotropical species found to date (1.6 mm long), it has unusually long antennal clubs, and some characters show resemblance to small Asian species or to the Malagasy genus Remansus Jordal. Genetic data from four genes nevertheless place this species as the sister lineage to all other Afrotropical species where it forms an isolated position corresponding to deviant morphological features.

Ancient diversity of Afrotropical Microborus: three endemic species – not one widespread https://zookeys.pensoft.net/article/14902/ ZooKeys 710: 33-42

DOI: 10.3897/zookeys.710.14902

Authors: Bjarte Jordal

Abstract: The primarily Neotropical genus Microborus Blandford is represented with three species in Africa and Madagascar. The previously recorded species from this region, M. boops Blandford, is a Neotropical species restricted to Central America and is likely not found in the Afrotropics. The previously recognised species in western parts of Africa is M. camerunus (Eggers) and is resurrected from synonymy under M. boops. Molecular and morphological data revealed a second species of this complex in Madagascar, M. brevisetosus Jordal. Another new species, M. angustus Jordal, co-occurs with M. camerunus in Cameroon. Substantial genetic divergence indicate that Microborus was established in the Afrotropical region long before human transport across oceans. A key to Afrotropical species is provided.

Scolytinae in hazelnut orchards of Turkey: clarification of species and identification key (Coleoptera, Curculionidae) https://zookeys.pensoft.net/article/15047/ ZooKeys 710: 65-76

DOI: 10.3897/zookeys.710.15047

Authors: Celal Tuncer, Milos Knizek, Jiri Hulcr

Abstract: Hazelnut, a very important cash crop in Turkey, is frequently colonized by bark and ambrosia beetle species (Scolytinae). Some scolytine species may cause economic damage while other species do not; therefore, proper identification is important in orchard management. Extensive sampling demonstrated that the most common pest species in Turkey’s hazelnut orchards are Anisandrus dispar, Xylosandrus germanus, and Xyleborinus saxesenii. Hypothenemus eruditus can also be common, but only colonizes branches that are already dead. Lymantor coryli, Hypoborus ficus, Taphrorychus ramicola, and Taphrorychus hirtellus are rare and do not causes damage to live plants. Xyleborinus saxesenii appears to have been frequently misidentified and misreported as either L. coryli or Xyleborus xylographus. The former is rare, and the latter probably does not occur in Turkey. To avoid future misidentifications, a dichotomous identification key is provided for bark and ambrosia beetles of hazelnut orchards in Turkey.

Austromonticola, a new genus of broad-nosed weevil (Coleoptera, Curculionidae, Entiminae) from montane areas of New Zealand https://zookeys.pensoft.net/article/12649/ ZooKeys 707: 73-130

DOI: 10.3897/zookeys.707.12649

Authors: Samuel D. J. Brown

Abstract: Austromonticola gen. n. is proposed for a group of eight New Zealand alpine broad-nosed weevil species, all of which are here described: A. atriarius sp. n. (type locality: Umbrella Mountains, Central Otago), A. caelibatus sp. n. (type locality: Ohau Range, Mackenzie), A. furcatus sp. n. (type locality: Old Man Range, Central Otago), A. inflatus sp. n. (type locality: Hawkdun Range, Central Otago), A. planulatus sp. n. (type locality: St Marys Range, Central Otago), A. postinventus sp. n. (type locality: Kirkliston Range, South Canterbury), A. mataura sp. n. (type locality: Mt Dick, Otago Lakes) and A. rotundus sp. n. (type locality: Old Man Range, Central Otago). All species occur exclusively above 1000 m elevation in the mountains of Central Otago and South Canterbury in the South Island. A phylogeny of the genus, including six outgroups, was inferred from 33 morphological characters. It resolved the genus as monophyletic, and revealed two strongly supported clades within Austromonticola. DNA sequences of four gene regions were obtained from five species. Of these, the 3' end of COI proved to be the most suitable for the identification of specimens. Females of all species have diagnostic secondary sexual structures on the elytra and ventrites. These structures are hypothesised to have evolved to assist with oviposition in and beside cushion plants or by selection for structures to mitigate the costs to females of prolonged mating.

Review of the genera of Conoderinae (Coleoptera, Curculionidae) from North America, Central America, and the Caribbean https://zookeys.pensoft.net/article/12080/ ZooKeys 683: 51-138

DOI: 10.3897/zookeys.683.12080

Authors: Salvatore S. Anzaldo

Abstract: The thirty-nine extant genera of Conoderinae known to occur in North America, Central America, and the Caribbean are reviewed based on external morphology. An identification key is provided along with diagnoses, distributions, species counts, and natural history information, when known, for each genus. Morphological character systems of importance for weevil classification are surveyed, potential relationships among the tribes and genera are discussed, and groups most in need of taxonomic and phylogenetic attention are identified. The following genera are transferred to new tribes: Acoptus LeConte, 1876 from the Lechriopini to the Othippiini(new placement) and the South American genus Hedycera Pascoe, 1870 from the Lechriopini to the Piazurini(new placement). Philides Champion, 1906 and Philinna Champion, 1906 are transferred from the Lechriopini to Conoderinaeincertae sedis(new placement) although their placement as conoderines is uncertain. The species Copturomimus cinereus Heller, 1895 is designated as the type species of the genus Copturomimus Heller, 1895.

Description of the immature stages of Larinus vulpes and notes on its biology (Coleoptera, Curculionidae, Lixinae) https://zookeys.pensoft.net/article/12560/ ZooKeys 679: 107-137

DOI: 10.3897/zookeys.679.12560

Authors: Jiří Skuhrovec, Semyon Volovnik, Rafał Gosik

Abstract: Mature larva and pupa of Larinus vulpes (Olivier, 1807) (Curculionidae: Lixinae: Lixini) are morphologically described for the first time and compared with known larvae and pupae of other Larinus species. Very high counts of larval body setae (pronotum with more than 25 setae and postdorsum on meso- and metathorax and also on abdominal segments I–VII with more than 12 setae) are characteristic features of the nominotypical subgenus Larinus. The biology of the species was studied in Ukraine. Echinops ruthenicus and E. sphaerocephalus were identified as host plants of both larvae and adults of this weevil based on the present research in Ukraine, which shows probably oligophagous. Overwintering beetles emerged at the end of May or earlier, then feeding and mating on the host plants. The highest level of adult activity was observed at the end of June. Larvae were endophagous within the flower heads. In July and August, the larvae pupated within inflorescences in a pupation cell. Adults exited the cells at the end of August and did not hibernate on the host plants. Sometimes, larvae and imagines of a new generation were found outside the flower heads in chambers constructed on the stems.

Nine new species are recognized as follows: Apodrosus alberti (type locality, Granma, Parque Nacional Pico Turquino), A. alternatus (type locality, Guantánamo, El Yunque), A. franklyni (type locality, Cienfuegos, Parque Nacional Pico San Juan), A. griseus (type locality, Santiago de Cuba, Siboney-Jutici Ecological Reserve), A. mensurensis (type locality, Holguin, Parque Nacional La Mensura-Piloto), A. pseudoalternatus (type locality, Matanzas, Varahicacos), A. beckeli (type locality, Guantánamo, 8 km W. Imias), A. sandersoni (type locality, Guantánamo, Loma Lafarola), and A. zayasi (type locality, Cienfuegos, Parque Nacional Pico San Juan). A key for their identification, descriptions, summaries of natural history information and data on distributions are presented. A molecular phylogeny based on 11 species of Apodrosus from Cuba, Hispaniola and Puerto Rico is reconstructed. A sister group relationship between Polydrusus and Apodrosus is recovered with a limited sampling of the former genus. The monophyly of Apodrosus is recovered with strong support. Cuban Apodrosus are not monophyletic. Five of the six sampled Cuban species form a clade, sister to an undescribed Apodrosus species from the Dominican Republic; and, Apodrosus alternatus is sister to A. quisqueyanus Girón & Franz, 2010, a species from the Dominican Republic. Biogeographic implications for Cuban species are discussed in light of the phylogeny.

Diversity and distribution of polyphagan water beetles (Coleoptera) in the Lake St Lucia system, South Africa https://zookeys.pensoft.net/article/11622/ ZooKeys 656: 51-84

DOI: 10.3897/zookeys.656.11622

Authors: Matthew S. Bird, David T. Bilton, Renzo Perissinotto

Abstract: Water beetles belonging to the suborder Polyphaga vary greatly in larval and adult ecologies, and fulfil important functional roles in shallow-water ecosystems by processing plant material, scavenging and through predation. This study investigates the species richness and composition of aquatic polyphagan assemblages in and around the St Lucia estuarine lake (South Africa), within the iSimangaliso Wetland Park, a UNESCO World Heritage Site. A total of 32 sites were sampled over three consecutive collection trips between 2013 and 2015. The sites encompassed a broad range of aquatic habitats, being representative of the variety of freshwater and estuarine environments present on the St Lucia coastal plain. Thirty-seven polyphagan taxa were recorded during the dedicated surveys of this study, in addition to seven species-level records from historical collections. Most beetles recorded are relatively widespread Afrotropical species and only three are endemic to South Africa. Samples were dominated by members of the Hydrophilidae (27 taxa), one of which was new to science (Hydrobiomorpha perissinottoi Bilton, 2016). Despite the fauna being dominated by relatively widespread taxa, five represent new records for South Africa, highlighting the poor state of knowledge on water beetle distribution patterns in the region. Wetlands within the dense woodland characterising the False Bay region of St Lucia supported a distinct assemblage of polyphagan beetles, whilst sites occurring on the Eastern and Western Shores of Lake St Lucia were very similar in their beetle composition. In line with the Afrotropical region as a whole, the aquatic Polyphaga of St Lucia appear to be less diverse than the Hydradephaga, for which 68 species were recorded during the same period. However, the results of the present study, in conjunction with those for Hydradephaga, show that the iSimangaliso Wetland Park contains a high beetle diversity. The ongoing and future ecological protection of not only the estuarine lake itself, but also surrounding freshwater wetlands, is imperative and should be taken into consideration during future management planning for the park.

Phylogenetic analysis of the genus Laparocerus, with comments on colonisation and diversification in Macaronesia (Coleoptera, Curculionidae, Entiminae) https://zookeys.pensoft.net/article/10097/ ZooKeys 651: 1-77

DOI: 10.3897/zookeys.651.10097

Authors: Antonio Machado, Eduardo Rodríguez-Expósito, Mercedes López, Mariano Hernández

Abstract: The flightless Entiminae weevil genus Laparocerus is the species-richest genus, with 237 species and subspecies, inhabiting Macaronesia (Madeira archipelago, Selvagens, Canary Islands) and the continental ‘Macaronesian enclave’ in Morocco (one single polytypic species). This is the second contribution to gain insight of the genus and assist in its systematic revision with a mitochondrial phylogenetic analysis. It centres on the Canarian clade, adding the 12S rRNA gene to the combined set of COII and 16S rRNA used in our first contribution on the Madeiran clade (here re-analysed). The nuclear 28S rRNA was also used to produce an additional 4-gene tree to check coherency with the 3-gene tree. A total of 225 taxa (95%) has been sequenced, mostly one individual per taxa. Plausible explanations for incoherent data (mitochondrial introgressions, admixture, incomplete lineage sorting, etc.) are discussed for each of the monophyletic subclades that are coincident with established subgenera, or are restructured or newly described. The overall mean genetic divergence (p-distance) among species is 8.2%; the mean divergence within groups (subgenera) ranks from 2.9 to 7.0% (average 4.6%), and between groups, from 5.4% to 12.0% (average 9.2%). A trustful radiation event within a young island (1.72 Ma) was used to calibrate and produce a chronogram using the software RelTime. These results confirm the monophyly of both the Madeiran (36 species and subspecies) and the Canarian (196 species and subspecies) clades, which originated ca. 11.2 Ma ago, and started to radiate in their respective archipelagos ca. 8.5 and 7.7 Ma ago. The Madeiran clade seems to have begun in Porto Santo, and from there it jumped to the Desertas and to Madeira, with additional radiations. The Canarian clade shows a sequential star-shape radiation process generating subclades with a clear shift from East to West in coherence with the decreasing age of the islands. Laparocerus garretai from the Selvagens belongs to a Canarian subclade, and Laparocerus susicus from Morocco does not represent the ancestral continental lineage, but a back-colonisation from the Canaries to Africa. Dispersal processes, colonisation patterns, and ecological remarks are amply discussed. Diversification has been adaptive as well as non-adaptive, and the role of ’geological turbulence’ is highlighted as one of the principal drivers of intra-island allopatric speciation. Based on the phylogenetic results, morphological features and distribution, five new monophyletic subgenera are described: Aridotrox subg. n., Belicarius subg. n., Bencomius subg. n., Canariotrox subg. n., and Purpuranius subg. n., totalling twenty subgenera in Laparocerus.

The morphology of the immature stages of two rare Lixus species (Coleoptera, Curculionidae, Lixinae) and notes on their biology https://zookeys.pensoft.net/article/9018/ ZooKeys 604: 87-116

DOI: 10.3897/zookeys.604.9018

Authors: Filip Trnka, Robert Stejskal, Jiří Skuhrovec

Abstract: The mature larvae and pupae of Lixus (Ortholixus) bituberculatus Smreczyński, 1968 and L. (Dilixellus) neglectus Fremuth, 1983 (Curculionidae: Lixinae: Lixini) are described and compared with known larvae of 21 other Lixus and 2 Hypolixus taxa. The mature larva and pupa of L. bituberculatus are the first immature stages described representing the subgenus Ortholixus. The larva of L. neglectus, in the subgenus Dilixellus, is distinguished from the known larvae of four species in this subgenus by having more pigmented sclerites on the larval body. All descriptions of mature larvae from the tribe Lixini, as do all known species from the tribe Cleonini, fit the diagnosis of the mature larva of the Lixinae subfamily. Furthermore, new biological information of these species in the Czech Republic, Slovakia and Romania is provided. For L. bituberculatus, a chicory, Cichorium intybus L. (Asteraceae), is identified as a host plant, and L. neglectus is found on dock Rumex thyrsiflorus Fingerh. (Polygonaceae). Both species are probably monophagous or oligophagous. Adults of L. bituberculatus often inhabit host plants growing in active, dry and sunny pastures with sparse patches without vegetation, being mostly active during the night in April/May and then again in September, when the highest activity levels are observed. Adults of L. neglectus inhabit dry grasslands on sandy soils with host plants, being active during the day from May to September, with the highest level of activity in May/June and September. The larvae of both species are borers in the stem and root of the host plant, and they pupate in root or root neck. Adults leave the pupation cells at the end of summer and do not hibernate in the host plants. Finally, Romania is a new geographic record for L. bituberculatus.

Evemphyron sinense, a new genus and species infesting legume seedpods in China (Coleoptera, Attelabidae, Rhynchitinae) https://zookeys.pensoft.net/article/6709/ ZooKeys 600: 89-101

DOI: 10.3897/zookeys.600.6709

Authors: Xiangyang Lv, Miguel A. Alonso-Zarazaga, Zhishu Xiao, Zhiliang Wang, Runzhi Zhang

Abstract: A new genus Evemphyron Alonso-Zarazaga, Lv & Wang, gen. n., belonging to AttelabidaeRhynchitinae, is described. Its single species, Evemphyron sinense Alonso-Zarazaga, Lv & Wang, sp. n., was reared from larvae found inside seed pods of the legume Callerya dielsiana (Fabaceae, Millettieae) in Sichuan Province (China). The species is figured and placed in the Deporaini because of the presence of minute labial palpi, the strongly crescentic apex of the postmentum, and the apodemes of male IX sternite and female VIII sternite curved sinistro-anterially near their cephalic end. It shows 3-segmented labial palpi and male sex patches on the procoxae, characters that suggest a basal position in the tribe.

The morphology of the immature stages of Metadonus vuillefroyanus (Capiomont, 1868) (Coleoptera, Curculionidae, Hyperini) and notes on its biology https://zookeys.pensoft.net/article/7847/ ZooKeys 589: 123-142

DOI: 10.3897/zookeys.589.7847

Authors: Jiří Skuhrovec, Petr Bogusch

Abstract: Last instar larva and pupa of Metadonus vuillefroyanus (Capiomont, 1868) (Curculionidae: Hyperini) are described and compared with known larvae of the other 43 hyperine taxa. The thorn-like setae located on distinct black protuberances on the larval body are characteristic features of the genus Metadonus and the subgenus Eririnomorphus of the genus Hypera. The biological singularity of this species was studied and described. The variable colouration of larvae has been confirmed in association with the variability of the host plant’s colouration at the studied localities. This species’ reported inability to spin cocoons has been disproven. A different type of cocoon with two layers, where the inner layer consists of proteins from Malpighian tubules while the outer layer contains soil particles, is described. This type of cocoon is unique compared with those known from other hyperines, which usually pupate on or above the ground and do not use substrate particles in building their cocoons.

Phylogenetic revision of Minyomerus Horn, 1876 sec. Jansen & Franz, 2015 (Coleoptera, Curculionidae) using taxonomic concept annotations and alignments https://zookeys.pensoft.net/article/6001/ ZooKeys 528: 1-133

DOI: 10.3897/zookeys.528.6001

Authors: Michael Andrew Jansen, Nico M. Franz

Abstract: This contribution adopts the taxonomic concept annotation and alignment approach. Accordingly, and where indicated, previous and newly inferred meanings of taxonomic names are individuated according to one specific source. Articulations among these concepts and pairwise, logically consistent alignments of original and revisionary classifications are also provided, in addition to conventional nomenclatural provenance information. A phylogenetic revision of the broad-nosed weevil genera Minyomerus Horn, 1876 sec. O’Brien & Wibmer (1982), and Piscatopus Sleeper, 1960 sec. O’Brien & Wibmer (1982) (Curculionidae [non-focal]: Entiminae [non-focal]: Tanymecini [non-focal]) is presented. Prior to this study, Minyomerus sec. O’Brien & Wibmer (1982) contained seven species, whereas the monotypic Piscatopus sec. O’Brien & Wibmer (1982) was comprised solely of P. griseus Sleeper, 1960 sec. O’Brien & Wibmer (1982). We thoroughly redescribe these recognized species-level entities and furthermore describe ten species as new to science: M. bulbifrons sec. Jansen & Franz (2015) (henceforth: [JF2015]), sp. n., M. aeriballux [JF2015], sp. n., M. cracens [JF2015], sp. n., M. gravivultus [JF2015], sp. n., M. imberbus [JF2015], sp. n., M. reburrus [JF2015], sp. n., M. politus [JF2015], sp. n., M. puticulatus [JF2015], sp. n., M. rutellirostris [JF2015], sp. n., and M. trisetosus [JF2015], sp. n. A cladistic analysis using 46 morphological characters of 22 terminal taxa (5/17 outgroup/ingroup) yielded a single most-parsimonious cladogram (L = 82, CI = 65, RI = 82). The analysis strongly supports the monophyly of Minyomerus [JF2015] with eight unreversed synapomorphies, and places P. griseus sec. O’Brien & Wibmer (1982) within the genus as sister to M. rutellirostris [JF2015]. Accordingly, Piscatopus sec. Sleeper (1960), syn. n. is changed to junior synonymy of Minyomerus [JF2015], and its sole member P. griseus sec. Sleeper (1960) is moved to Minyomerus [JF2015] as M. griseus [JF2015], comb. n. In addition, the formerly designated type M. innocuus Horn, 1876 sec. Pierce (1913), syn. n. is changed to junior synonymy of M. microps (Say, 1831) [JF2015] which has priority. The genus is widespread throughout western North America, ranging from Canada to Mexico and Baja California. Apparent patterns of interspecific diversity of exterior and genitalic morphology, varying host plant ranges, overlapping and widely extending species distributions, suggest an early origin for Minyomerus [JF2015], with a diversification that likely followed the development of North American desert biomes. Three species in the genus – i.e., M. languidus Horn, 1876 [JF2015], M. microps [JF2015], and M. trisetosus [JF2015] – are putatively considered parthenogenetic.

Ninety-eight new species of Trigonopterus weevils from Sundaland and the Lesser Sunda Islands https://zookeys.pensoft.net/article/4347/ ZooKeys 467: 1-162

DOI: 10.3897/zookeys.467.8206

Authors: Alexander Riedel, Rene Tänzler, Michael Balke, Cahyo Rahmadi, Yayuk R. Suhardjono

Abstract: The genus Trigonopterus Fauvel, 1862 is highly diverse in Melanesia. Only one species, Trigonopterus amphoralis Marshall, 1925 was so far recorded West of Wallace’s Line (Eastern Sumatra). Based on focused field-work the fauna from Sundaland (Sumatra, Java, Bali, Palawan) and the Lesser Sunda Islands (Lombok, Sumbawa, Flores) is here revised. We redescribe T. amphoralis Marshall and describe an additional 98 new species: T. acuminatus sp. n., T. aeneomicans sp. n., T. alaspurwensis sp. n., T. allopatricus sp. n., T. allotopus sp. n., T. angulicollis sp. n., T. argopurensis sp. n., T. arjunensis sp. n., T. asper sp. n., T. attenboroughi sp. n., T. baliensis sp. n., T. batukarensis sp. n., T. bawangensis sp. n., T. binodulus sp. n., T. bornensis sp. n., T. cahyoi sp. n., T. costipennis sp. n., T. cuprescens sp. n., T. cupreus sp. n., T. dacrycarpi sp. n., T. delapan sp. n., T. dentipes sp. n., T. diengensis sp. n., T. dimorphus sp. n., T. disruptus sp. n., T. dua sp. n., T. duabelas sp. n., T. echinatus sp. n., T. empat sp. n., T. enam sp. n., T. fissitarsis sp. n., T. florensis sp. n., T. foveatus sp. n., T. fulgidus sp. n., T. gedensis sp. n., T. halimunensis sp. n., T. honjensis sp. n., T. ijensis sp. n., T. javensis sp. n., T. kalimantanensis sp. n., T. kintamanensis sp. n., T. klatakanensis sp. n., T. lampungensis sp. n., T. latipes sp. n., T. lima sp. n., T. lombokensis sp. n., T. merubetirensis sp. n., T. mesehensis sp. n., T. micans sp. n., T. misellus sp. n., T. palawanensis sp. n., T. pangandaranensis sp. n., T. paraflorensis sp. n., T. pararugosus sp. n., T. parasumbawensis sp. n., T. pauxillus sp. n., T. payungensis sp. n., T. porcatus sp. n., T. pseudoflorensis sp. n., T. pseudosumbawensis sp. n., T. punctatoseriatus sp. n., T. ranakensis sp. n., T. relictus sp. n., T. rinjaniensis sp. n., T. roensis sp. n., T. rugosostriatus sp. n., T. rugosus sp. n., T. rutengensis sp. n., T. saltator sp. n., T. santubongensis sp. n., T. sasak sp. n., T. satu sp. n., T. schulzi sp. n., T. sebelas sp. n., T. sembilan sp. n., T. sepuluh sp. n., T. seriatus sp. n., T. serratifemur sp. n., T. setifer sp. n., T. silvestris sp. n., T. singkawangensis sp. n., T. singularis sp. n., T. sinuatus sp. n., T. squalidus sp. n., T. sumatrensis sp. n., T. sumbawensis sp. n., T. sundaicus sp. n., T. suturalis sp. n., T. syarbis sp. n., T. telagensis sp. n., T. tepalensis sp. n., T. tiga sp. n., T. trigonopterus sp. n., T. tujuh sp. n., T. ujungkulonensis sp. n., T. variolosus sp. n., T. vulcanicus sp. n., T. wallacei sp. n.. All new species are authored by the taxonomist-in-charge, Alexander Riedel. Most species belong to the litter fauna of primary wet evergreen forests. This habitat has become highly fragmented in the study area and many of its remnants harbor endemic species. Conservation measures should be intensified, especially in smaller and less famous sites to minimize the number of species threatened by extinction.

The new genus Pheude (Coleoptera, Curculionidae, Cossoninae) with description of a new species from mainland China https://zookeys.pensoft.net/article/4352/ ZooKeys 466: 29-41

DOI: 10.3897/zookeys.466.8032

Authors: Youssef M. Omar, Runzhi Zhang, Steve R. Davis

Abstract: A new weevil, Pheude punctatus gen. et sp. n., of the tribe Dryotribini in Cossoninae, is described from Guangdong Province, South China. It differs from the related genera Dryotribus Horn and Microtribodes Morimoto in having antennae with seven articles and a distinct scutellum, and from Ochronanus Pascoe and Stenomimus Wollaston in having long antennae, a rostrum with a medio-longitudinal furrow beginning at the posterior margin of the eyes and extending approximately midway on the rostrum, and a moderately elevated, medio-longitudinal carina extending the full length of the pronotum. Other diagnostic characters and illustrations are provided. A key to the genera of Dryotribini known from China is given.

On the identity of some weevil species described by Johann Christian Fabricius (1745–1808) in the Museum of Zoology of Copenhagen (Coleoptera, Cucujoidea, Curculionoidea, Tenebrionoidea) https://zookeys.pensoft.net/article/4210/ ZooKeys 451: 61-91

DOI: 10.3897/zookeys.451.8462

Authors: Miguel Alonso-Zarazaga

Abstract: The types of thirty-two nominal weevil species described by Johann Christian Fabricius are reviewed and lecto- and paralectotypes are designated for twenty-two of them. A neotype is designated for Curculio sticticus Fabricius, 1777. Protapion varipes (Germar, 1817) is declared a nomen protectum over Curculio flavipes Fabricius, 1775. Based on a study of syntypes, Rhinomacer curculioides Fabricius, 1781 is confirmed as a member of Mycterus (Mycteridae), Bruchus undatus Fabricius, 1787 is tentatively transferred to Erotylidae, Curculio fulvirostris Fabricius, 1787 and Anthribus roboris Fabricius, 1798 are confirmed as members of Salpingus (Salpingidae), and Brachycerus cristatus Fabricius, 1798 is transferred to Tenebrionidae. Based on lectotype designation, Curculio caninus Fabricius, 1792 is confirmed as a synonym of Sitona lineatus (Linnaeus, 1758) and Curculio innocuus Fabricius, 1802 as a synonym of Cneorhinus barcelonicus (Herbst, 1797). Bruchus rufipes Fabricius, 1792 is not considered an available species name, but a later use of Bruchus rufipes Olivier, 1790. Cossonus incisus Pascoe, 1885 is reinstated as valid from synonymy under Cossonus illigeri Champion, 1909 and Cossonus vulneratus Illiger, 1805 from synonymy under Cossonus canaliculatus (Fabricius, 1792) (a primary homonym of Curculio canaliculatus Olivier, 1791). Cossonus canaliculatus Fabricius, 1802 is a secondary homonym of the former and is replaced with Cossonus incisus. Salpingus fulvirostris (Fabricius, 1787) is reinstated as valid from synonymy under Salpingus planirostris (Fabricius, 1787), a primary homonym of Curculio planirostris Piller & Mitterpacher, 1783. The following new combinations are proposed: Brachysomus erinaceus (Fabricius, 1802) (from Curculio), Bronchus ferus (Gyllenhal, 1840) (from Hipporhinus), Bronchus glandifer (Fabricius, 1792) (from Curculio), Bronchus nivosus (Sparrman, 1785) (from Curculio), Bronchus sparrmani (Gyllenhal, 1833) (from Hipporhinus), Coelocephalapion atrirostre (Fabricius, 1802) (from Attelabus), Nerthops sticticus (Fabricius, 1777) (from Curculio), Piezotrachelus crotalariae (Fabricius, 1802) (from Attelabus), and Poropterus granulatus (Fabricius, 1802) (from Curculio). The junior homonym Brachycerus uva Fabricius, 1792 (non Sparrman, 1785) is replaced by Brachycerus fabricii nom. n. The following new synonymies are established: Brachycerus obesus (Fabricius, 1775) = Curculio scalaris Fabricius, 1777, syn. n., Brachyderes lusitanicus (Fabricius, 1781) = Curculio moratus Fabricius, 1798, syn. n., Brachypera (Brachypera) crinita (Boheman, 1834) = Curculio striatus Fabricius, 1787, syn. n., Brachysomus erinaceus (Fabricius, 1802) = Brachysomus villosulus (Germar, 1824), syn. n., Bronchus abruptecostatus (Gyllenhal, 1833) = Curculio spectrum Fabricius, 1802, syn. n., Bronchus nivosus (Sparrman, 1785) = Curculio recurvus Fabricius, 1802, syn. n., Camptorhinus tibialis (Sparrman, 1785) = Rhynchaenus alienatus Fabricius, 1802, syn. n., Coelocephalapion atrirostre (Fabricius, 1802) = Coelocephalapion luteirostre (Gerstäcker, 1854), syn. n., Cyrtoderes cristatus (DeGeer, 1778) (Tenebrionidae) = Brachycerus cristatus Fabricius, 1798, syn. n., Desmidophorus hebes (Fabricius, 1781) = Curculio tuberculatus Fabricius, 1792, syn. n., Donus salviae (Schrank, 1789) = Curculio denticornis Fabricius, 1798, syn. n., Exomias holosericeus (Fabricius, 1802) = Exomias chevrolati (Boheman, 1842), syn. n., Nerthops sticticus (Fabricius, 1777) = Nerthops guttatus (Olivier, 1807), syn. n., Phyllobius oblongus (Linnaeus, 1758) = Curculio mali Fabricius, 1782, syn. n., and Rhinocyllus conicus (Froelich, 1792) = Bruchus punctatus Fabricius, 1798, syn. n. Bronchus synthesys sp. n. is described to represent the concept of Hipporhinus spectrum sensu Marshall, 1904, a misidentification.

A taxonomic monograph of Nearctic Scolytus Geoffroy (Coleoptera, Curculionidae, Scolytinae) https://zookeys.pensoft.net/article/4202/ ZooKeys 450: 1-182

DOI: 10.3897/zookeys.450.7452

Authors: Sarah M. Smith, Anthony I. Cognato

Abstract: The Nearctic bark beetle genus Scolytus Geoffroy was revised based in part on a molecular and morphological phylogeny. Monophyly of the native species was tested using mitochondrial (COI) and nuclear (28S, CAD, ArgK) genes and 43 morphological characters in parsimony and Bayesian phylogenetic analyses. Parsimony analyses of molecular and combined datasets provided mixed results while Bayesian analysis recovered most nodes with posterior probabilities >90%. Native hardwood- and conifer-feeding Scolytus species were recovered as paraphyletic. Native Nearctic species were recovered as paraphyletic with hardwood-feeding species sister to Palearctic hardwood-feeding species rather than to native conifer-feeding species. The Nearctic conifer-feeding species were monophyletic. Twenty-five species were recognized. Four new synonyms were discovered: S. praeceps LeConte, 1868 (= S. abietis Blackman, 1934; = S. opacus Blackman, 1934), S. reflexus Blackman, 1934 (= S. virgatus Bright, 1972; = S. wickhami Blackman, 1934). Two species were reinstated: S. fiskei Blackman, 1934 and S. silvaticus Bright, 1972. A diagnosis, description, distribution, host records and images were provided for each species and a key is presented to all species.

Classification of weevils as a data-driven science: leaving opinion behind https://zookeys.pensoft.net/article/4032/ ZooKeys 439: 1-18

DOI: 10.3897/zookeys.439.8391

Authors: Bjarte Jordal, Sarah Smith, Anthony Cognato

Abstract: Data and explicit taxonomic ranking criteria, which minimize taxonomic change, provide a scientific approach to modern taxonomy and classification. However, traditional practices of opinion-based taxonomy (i.e., mid-20th century evolutionary systematics), which lack explicit ranking and naming criteria, are still in practice despite phylogenetic evidence. This paper discusses a recent proposed reclassification of weevils that elevates bark and ambrosia beetles (Scolytinae and Platypodinae) to the ranks of Family. We demonstrate that the proposed reclassification 1) is not supported by an evolutionary systematic justification because the apparently unique morphology of bark and ambrosia beetles is shared with other unrelated wood-boring weevil taxa; 2) introduces obvious paraphyly in weevil classification and hence violates good practices on maintaining an economy of taxonomic change; 3) is not supported by other taxonomic naming criteria, such as time banding. We recommend the abandonment of traditional practices of an opinion-based taxonomy, especially in light of available data and resulting phylogenies.

Taxonomic revision of the East Asian genus Scleropteroides Colonnelli, 1979 (Coleoptera, Curculionidae, Ceutorhynchinae) https://zookeys.pensoft.net/article/4020/ ZooKeys 437: 45-86

DOI: 10.3897/zookeys.437.6563

Authors: Junhao Huang, Hiraku Yoshitake, Runzhi Zhang, Motomi Ito

Abstract: The genus Scleropteroides Colonnelli, 1979 (Ceutorhynchinae: Scleropterini) was revised on the basis of detailed morphological observations. The genus was redefined to include three species from East Asia: S. hypocrita (Hustache, 1916) is redescribed and recorded from northeastern China and northern Korea for the first time; S. horridulus (Voss, 1958) is redescribed with new records from southern Korea; S. insularis Voss, 1971 was moved from synonymy with S. hypocrita to that with S. horridulus (syn. n.), and S. longiprocessus Huang & Yoshitake, sp. n. is described as new, sympatric with S. hypocrita in Japan. All the species are associated with woody Rubus species (Rosaceae). A key to species, habitus photographs, illustrations of important characters, and distribution maps are provided for each species.

A taxonomic revision of Limnobaris Bedel in the strict sense (Coleoptera, Curculionidae, Baridinae), with particular emphasis on the species found in China https://zookeys.pensoft.net/article/3850/ ZooKeys 416: 41-66

DOI: 10.3897/zookeys.416.7164

Authors: Jens Prena, Boris Korotyaev, Zhiliang Wang, Li Ren, Ning Liu, Runzhi Zhang

Abstract: The genus name Limnobaris Bedel is applied in a restricted sense to baridine weevils with a covered pygidium and non-prominent, decussate mandibles which occur on sedges in the Palaearctic Region and immediately adjacent parts of tropical Southeast Asia. Calyptopygus Marshall and Pertorcus Voss are syn. n. of Limnobaris. Some species from Africa and the Americas are maintained provisionally in Limnobaris in the widest sense but will need to be transferred to other genera in future studies. A total of eleven species is recognized in Asia, two of which are widespread and occur also in the Western Palaearctic Region. Limnobaris martensi Korotyaev sp. n. is described from Nepal. Pertorcus tibialis basalis Voss is raised to species rank, as L. basalis (stat. prom.). New or reestablished synonyms are L. dolorosa (Goeze) (= L. jucunda Reitter, = L. koltzei Reitter), L. tibialis (Voss) (= Pertorcus tibialis pilifer Voss) and L. t-album (Linnaeus) (= L. bedeli Reitter, = Baridius crocopelmus Gyllenhal, = L. sahlbergi Reitter, = L. scutellaris Reitter, = Baris t-album sculpturata Faust). Calandra uniseriata Dufour is considered a junior synonym of Sitophilus oryzae (L.) (syn. n.). A key for identification and a distribution map are provided.

A new genus of nemonychid weevil from Burmese amber (Coleoptera, Curculionoidea) https://zookeys.pensoft.net/article/3779/ ZooKeys 405: 127-138

DOI: 10.3897/zookeys.405.6475

Authors: Steve Davis, Michael Engel

Abstract: The first fossil nemonychid (Nemonychidae) in Burmese amber, belonging to the subfamily Rhinorhynchinae, is described and figured as Burmonyx zigrasi Davis and Engel, gen. n. and sp. n. While this specimen also comprises the first definitive record of the subfamily in the Asian continent, other compression fossils exist at least from the Yixian Formation of China and the Karatau site of Kazakhstan which may also deserve placement within this group. Although several important areas of the body are obscured by the shape and fragmented condition of the amber piece, a sufficient number of features are visible to consider adequate placement within Rhinorhynchinae, including the fairly strongly punctate elytral striae and appendiculate, nearly bifid pretarsal claws.

Taxonomic revision of the genus Stenocyphus Marshall (Coleoptera, Curculionidae) from Brazil https://zookeys.pensoft.net/article/3600/ ZooKeys 357: 29-43

DOI: 10.3897/zookeys.357.5854

Authors: Maria del Rio, Analía Lanteri

Abstract: Stenocyphus Marshall, 1922 (Entiminae, Naupactini) includes three species: the type species S. bituberosus (Gyllenhal, 1833), S. tuberculatus (Hustache, 1938), comb. n. herein transferred from Neoericydeus Hustache, 1938, and S. sextuberosus sp. n. The genus is endemic to the Atlantic forests of the states of Espirito Santo, Rio de Janeiro and São Paulo, Brazil and is mainly characterized by the presence of humped elytra bearing large conical tubercles on the intervals 5, or 3 and 5, or 3, 5 and 7. It shares some external morphological characters with Hadropus Schoenherr, 1826 and the Brazilian species of Cyrtomon Schoenherr 1823, but its phylogenetic position is uncertain. Herein we provide a diagnostic key to separate Stenocyphus from those genera, generic and species redescriptions or descriptions, a key to species, habitus photographs, line drawings of genitalia, and a discussion of the patterns of elytral tubercles in unrelated genera of Neotropical broad-nosed weevils.

Deep phylogenetic divergence between Scolytoplatypus and Remansus, a new genus of Scolytoplatypodini from Madagascar (Coleoptera, Curculionidae, Scolytinae) https://zookeys.pensoft.net/article/3537/ ZooKeys 352: 9-33

DOI: 10.3897/zookeys.352.6212

Authors: Bjarte Jordal

Abstract: Scolytoplatypodini Blandford is a monotypic tribe of ambrosia beetles found in Asia, Madagascar and Africa. Only three species are currently known from Madagascar and four additional species are here described as new to science. Phylogenetic analyses of morphological and molecular data revealed that four of the seven endemic species are deeply separated from all other species by genetic and distinct morphological characters and therefore placed in a new genus Remansus Jordal. The split between this ancient lineage and Scolytoplatypus Schaufuss was estimated to approximate Palaeocene age (63 Ma), extending the minimum age of ambrosia feeding for this tribe to the beginning of the Palaeocene‒Eocene thermal maximum (PETM). In addition to the ancient origin of Remansus in Madagascar during the Palaeocene, a second origin occurred in Scolytoplatypus no more than 13 Ma. A geographical origin of the latter in South-Eastern Africa was unequivocally inferred from the phylogenies.

Occurrence of species of the genus Pityophthorus Eichhoff (Coleoptera, Curculionidae, Scolytinae) in the province of Quebec, Canada https://zookeys.pensoft.net/article/3468/ ZooKeys 348: 97-124

DOI: 10.3897/zookeys.348.6029

Authors: Valentin Popa, Louis Morneau, Céline Piché, André Deshaies, Eric Bauce, Claude Guertin

Abstract: Twig beetles in the genus Pityophthorus Eichhoff, 1864 include more than 300 species worldwide, with maximum diversity in tropical and subtropical regions. To date, approximately 50 species of Pityophthorus have been recorded in Canada, and these species are associated mainly with coniferous trees. Since 1981, no comprehensive study on this difficult taxonomic group has been conducted in Quebec, Canada, most likely due to their limited significance as forest pests. Based on data gathered from five years of field sampling in conifer seed orchards and compiled from various entomological collections, the distribution of Pityophthorus species in Quebec is presented. Approximately 291 new localities were recorded for the Pityophthorus species. Five species-group taxa, namely P. puberulus (LeConte, 1868), P. pulchellus pulchellus Eichhoff, 1869, P. pulicarius (Zimmermann, 1868), P. nitidus Swaine, 1917, and P. cariniceps LeConte&Horn, 1876 were the most widespread. In contrast, P. consimilis LeConte, 1878, P. intextus Swaine, 1917, P. dentifrons Blackman, 1922, P. ramiperda Swaine, 1917, and P. concavus Blackman, 1928 display a notably limited distribution. In addition, the first distribution records of P. intextus and P. biovalis Blackman, 1922 are furnished, and the subspecies P. murrayanae murrayanae Blackman, 1922 is reported from Quebec for the second time. Moreover, distribution maps are provided for all Pityophthorus species recorded in the province of Quebec.

DOI: 10.3897/zookeys.333.6122

Authors: Miguel Alonso-Zarazaga

Abstract: A new genus Moreiba is described for Strophosoma canariense Franz, 1995 (type species) and placed in Laparocerini. It differs from Laparocerus Schoenherr, 1834 by the small size, the strongly transverse rostrum, the dense longitudinal strigosity on head and rostrum, the body covered by dense, adpressed scales and short, semierect subspatulate to parallel setae, the slender antennae with bisinuate scape and short oval club, the granulate pronotum and all tibiae lacking a mucro in both sexes. Moreiba canariensis (Franz, 1995), comb. n., is the only described species, distributed in El Hierro and Gran Canaria. The tribal placement of the genera Aphyonotus Faust, 1895, Asmaratrox Heller, 1909, Straticus Pascoe, 1886 and Cyrtozemia Pascoe, 1872 is discussed.

DOI: 10.3897/zookeys.317.5477

Authors: Miguel Alonso-Zarazaga

Abstract: The type specimens of species of Apionidae described by Carl Peter Thunberg are reviewed and lecto- and paralectotypes are designated for Apion craccae Thunberg, 1813, Apion limbatum Thunberg, 1813, Apion punctigerum Thunberg, 1815 and Apion astragali Thunberg, 1815. A new genus Thunbergapion (type species Apion limbatum Thunberg, 1813) is described, figured and placed in the tribe Aplemonini Kissinger, 1968. The new combination Thunbergapion limbatum (Thunberg, 1813) is proposed. A key to the known South African genera of the tribe is given. The following new synonymies are established: Oxystoma craccae (Linnaeus, 1767) = Apion craccae Thunberg, 1813 syn. n., Ischnopterapion (Ischnopterapion) loti (Kirby, 1808) = Apion punctigerum Thunberg, 1815, syn. n., and Pseudoprotapion astragali (Paykull, 1800) = Apion astragali Thunberg, 1815, syn. n.

The subtribes and genera of the tribe Listroderini (Coleoptera, Curculionidae, Cyclominae): Phylogenetic analysis with systematic and biogeographical accounts https://zookeys.pensoft.net/article/3720/ ZooKeys 273: 15-71

DOI: 10.3897/zookeys.273.4116

Authors: Juan Morrone

Abstract: The phylogenetic relationships of the genera of Listroderini LeConte, 1876 are analyzed based on 58 morphological characters. The genera are grouped in four clades, which are given subtribal status: Macrostyphlina new subtribe (Adioristidius, Amathynetoides, Andesianellus, Macrostyphlus, Nacodius and Puranius), Palaechthina Brinck, 1948 (Anorthorhinus, Gunodes, Haversiella, Inaccodes, Listronotus, Neopachytychius, Palaechthus, Palaechtodes, Steriphus and Tristanodes), Falklandiina new subtribe (Falklandiellus, Falklandiopsis, Falklandius, Gromilus, Lanteriella, Liparogetus, Nestrius and Telurus), and Listroderina (Acroriellus, Acrorius, Acrostomus, Antarctobius, Germainiellus, Hyperoides, Lamiarhinus, Listroderes, Methypora, Philippius, Rupanius and Trachodema). The subtribes are characterized and keys to identify them and their genera are provided. Listroderini have four main biogeographical patterns: Andean (Macrostyphlina), Andean-New Zealand (Falklandiina), Andean-Neotropical-Australian (Listroderina) and Andean-Neotropical-Australian-New Zealand-Nearctic-Tristan da Cunha-Gough islands (Palaechthina). Geographical paralogy, particularly evident in the Subantarctic subregion of the Andean region, suggests that Listroderini are an ancient Gondwanic group, in which several extinction events might have obscured relationships among the areas.

Rhabdorrhynchus echii (Brahm, 1790), a “forgotten” name (Coleoptera, Curculionidae, Lixinae) https://zookeys.pensoft.net/article/3361/ ZooKeys 243: 95-99

DOI: 10.3897/zookeys.243.3976

Authors: Massimo Meregalli, Miguel Alonso-Zarazaga

Abstract: The application of the name Curculio echii Brahm, 1790 is discussed. Based on the description it is evident that it should be applied to a German species of the genus Rhabdorrhynchus, and that it has priority over the name currently applied to the species, R. seriegranosus Chevrolat, 1873. The new combination Rhab-dorrhynchus echii (Brahm, 1790) is proposed. As there is a lack of any type material of C. echii a neotype is designated. Based on the study of the type specimen, R. seriegranosus is restored as a valid species.

New genus and species of broad-nosed weevils from Baltic amber and notes on fossils of the subfamily Entiminae (Coleoptera, Curculionidae) https://zookeys.pensoft.net/article/2345/ ZooKeys 160: 73-96

DOI: 10.3897/zookeys.160.2108

Authors: Nikolai Yunakov, Alexander Kirejtshuk

Abstract: Arostropsis groehni gen. et sp. n. is described from Baltic amber and temporarily placed in the tribe Naupactini. It differs from all recent Naupactini genera with open corbels by very short and flattened scape, distinct lateral carina of the pronotum and elytra, and the rostrum distinctly narrower than the head capsule. The shape of head in the extinct genus is somewhat similar to that of the extant Naupactini genera with enclosed corbels (Platyomus Sahlberg, 1823 and Aptolemus Schoenherr, 1842), but differs in the slender body, open corbels, very short antennal scape and epifrons without a median sulcus (only a longitudinal depression is slightly visible). It is also similar to the Tanymecine genus Pandeleteius Schoenherr, 1834 in general appearance, but distinct by the straight anterior edge of the pronotum, lack of postocular spurs, lobes, and vibrissae, a slightly sloping elytral declivity, lateral ridges on the pronotum, subflattened antennal scape, elongate rostrum, and sparsely setose epistome. A new synonymy of the generic names Protonaupactus Zherikhin, 1971 and Sucinophyllobius Wanat & Borowiec, 1986, syn. n., is established. The Madagascan genus Corecaulus Fairmaire, 1903 is transferred from the tribe Naupactini to the Brachyderini because of its connate claws and the similarity in chaetotaxy of the epistomal area with African and Madagascar Brachyderini genera. A key to the identification of known Baltic amber genera of Entiminae is proposed. A checklist of the prepleistocene fossil Entiminae, based on V.V. Zherikhin’s data, with remarks and corrections, is presented.

Two new genera of Nanophyidae with six desmomeres (Coleoptera, Curculionoidea) https://zookeys.pensoft.net/article/2703/ ZooKeys 125: 35-50

DOI: 10.3897/zookeys.125.1719

Authors: Miguel Alonso-Zarazaga, Helene Perrin

Abstract: A new genus Lyalia is described in Nanophyidae and three species are included in it: Lyalia curvata sp. n. (Vietnam), L. robusta (Pic, 1921), comb. n. (from Nanophyes) (Java, Bali, Laos) and L. albolineata (Pajni & Bhateja, 1982), comb. n. (from Ctenomerus) (India: Assam). Ctenomerus lagerstroemiae G. A. K. Marshall, 1923 is a syn. n. of L. robusta. Thus, the genus Ctenomerus Schoenherr, 1843 is restricted to the Afrotropical Realm. Kantohia gen. n. is erected for Kantohia taiwana (Kantoh & Kojima, 2009) (from Shiva) (Taiwan). A key to the Nanophyinae genera with six desmomeres is presented.

Obrieniolus, a new monotypic genus of Naupactini (Coleoptera, Curculionidae, Entiminae) from the Peruvian Andes and its phylogenetic placement https://zookeys.pensoft.net/article/2458/ ZooKeys 102: 51-60

DOI: 10.3897/zookeys.102.1240

Authors: Maria del Rio, Analia Lanteri

Abstract: A new monotypic genus of Naupactini (Coleoptera: Curculionidae), Obrieniolus del Río is described based on the new species Obrieniolus robustus del Río, endemic to Peru. This genus is easily recognized by the black, denuded and shiny integument, with imbricate microsculpture and the rounded body, with short, cordiform and moderately convex elytra. According to a cladistic analysis based on 69 continuous and discrete morphological characters, the new genus is the sister taxon of a group formed by Amitrus Schoenherr, Trichocyphus Heller, Amphideritus Schoenherr, Asymmathetes Wibmer & O’Brien and Galapaganus Lanteri. The paper includes habitus photographs, line drawings of genitalia, mouthparts, and other external features of taxonomic value, and a dichotomous key to the genera of Naupactini distributed in the South American Transition Zone.

Taxonomic redescription and biological notes on Diaugia angusta (Diptera, Tachinidae): parasitoid of the palm boring weevils Metamasius ensirostris and M. hemipterus (Coleoptera, Dryophthoridae) https://zookeys.pensoft.net/article/2235/ ZooKeys 84: 23-38

DOI: 10.3897/zookeys.84.756

Authors: Silvio Nihei, Ronaldo Pavarini

Abstract: Diaugia angusta Perty, 1833 is a Neotropical species of Tachinidae (Diptera) reported here as a parasitoid of Metamasius ensirostris (Germar, 1824) and M. hemipterus (Linnaeus, 1758) (Coleoptera: Dryophthoridae) in Brazil. Several species of Dryophthoridae and Curculionidae cause damage to bromeliad and palm species, and most are regarded as pests. In the present study, the male and female of D. angusta are morphologically characterized and illustrated to provide a means for the identification of this parasitoid. Data obtained from preliminary field research show that natural parasitism of Metamasius pupae by D. angusta varies by year but can reach nearly 30%. A network of parasitoid-host interactions among tachinid parasitoids and coleopteran hosts reported as bromeliad and palm pests (Dryophthoridae and Curculionidae) in the Americas indicates that the species of the tribe Dexiini sensu lato (including D. angusta) might be promising as biological control agents of these pests.

Mitochondrial phylogenies in the light of pseudogenes and Wolbachia: re-assessment of a bark beetle dataset https://zookeys.pensoft.net/article/2324/ ZooKeys 56: 269-280

DOI: 10.3897/zookeys.56.531

Authors: Wolfgang Arthofer, Dimitrios Avtzis, Markus Riegler, Christian Stauffer

Abstract: Phylogenetic studies based on mtDNA become increasingly questioned because of potential pitfalls due to mitochondrial pseudgenes and mitochondrial selective sweeps. While the inclusion of nuclear markers should preferentially be considered for future studies, there is no need to abandon mtDNA as long as tests for the known mtDNA artefacts are performed. In this study we present additional data and test previous phylogeographical studies of Pityogenes chalcographus. We did not detect nuclear copies (numts) of the previously used mitochondrial markers by performing a combined long range/nested PCR of the COI gene and by an in silico analysis of the COI sequence data. This confirms the robustness of our previous phylogenetic study of P. chalcographus. Results of an in-situ hybridization of Wolbachia in P. chalcographus confirm the presence of this endosysmbiont in this species. However, we did not detect a correlation between infection status, geographical region and mtDNA haplotypes. The hybridisation data also support a previous hypothesis that infections do not result from parasitoids or parasitic nematodes, insect surface or laboratory contaminations and are hence a true infection of P. chalcographus. We conclude that the deep structure found in mitochondrial populations of P. chalcographus indeed represents the evolutionary history of European populations.

Observations on sex ratio and behavior of males in Xyleborinus saxesenii Ratzeburg (Scolytinae, Coleoptera) https://zookeys.pensoft.net/article/2323/ ZooKeys 56: 253-267

DOI: 10.3897/zookeys.56.530

Authors: Peter Biedermann

Abstract: Strongly female-biased sex ratios are typical for the fungal feeding haplodiploid Xyleborini (Scolytinae, Coleoptera), and are a result of inbreeding and local mate competition (LMC). These ambrosia beetles are hardly ever found outside of trees, and thus male frequency and behavior have not been addressed in any empirical studies to date. In fact, for most species the males remain undescribed. Data on sex ratios and male behavior could, however, provide important insights into the Xyleborini’s mating system and the evolution of inbreeding and LMC in general. In this study, I used in vitro rearing methods to obtain the first observational data on sex ratio, male production, male and female dispersal, and mating behavior in a xyleborine ambrosia beetle. Females of Xyleborinus saxesenii Ratzeburg produced between 0 and 3 sons per brood, and the absence of males was relatively independent of the number of daughters to be fertilized and the maternal brood sex ratio. Both conformed to a strict LMC strategy with a relatively precise and constant number of males. If males were present they eclosed just before the first females dispersed, and stayed in the gallery until all female offspring had matured. They constantly wandered through the gallery system, presumably in search of unfertilized females, and attempted to mate with larvae, other males, and females of all ages. Copulations, however, only occurred with immature females. From galleries with males, nearly all females dispersed fertilized. Only a few left the natal gallery without being fertilized, and subsequently went on to produce large and solely male broods. If broods were male-less, dispersing females always failed to found new galleries.

Abstract: Invasive bark beetles are posing a major threat to forest resources around the world. DAISIE’s web-based and printed databases of invasive species in Europe provide an incomplete and misleading picture of the alien scolytines and platypodines. We present a review of the alien bark beetle fauna of Europe based on primary literature through 2009. We find that there are 18 Scolytinae and one Platypodinae species apparently established in Europe, from 14 different genera. Seventeen species are naturalized. We argue that Trypodendron laeve, commonly considered alien in Europe, is a native species; conversely, we hypothesize that Xyleborus pfeilii, which has always been treated as indigenous, is an alien species from Asia. We also point out the possibility that the Asian larch bark beetle Ips subelongatus is established in European Russia. We show that there has been a marked acceleration in the rate of new introductions to Europe, as is also happening in North America: seven alien species were first recorded in the last decade. We present information on the biology, origins, and distributions of the alien species. All but four are polyphagous, and 11 are inbreeders: two traits which increase invasiveness. Eleven species are native to Asia, six to the Americas, and one is from the Canary Islands. The Mediterranean is especially favorable for invasives, hosting a large proportion of the aliens (8/18). Italy, Spain and France have the largest numbers of alien species (15, 10 and 7 respectively). We point out that the low numbers for at least some countries is likely due to under-reporting. Finally, we discuss the difficulties associated with identifying newly invasive species. Lack of good illustrations and keys hinder identification, particularly for species coming from Asia and Oceania.

First Records of Xyleborinus octiesdentatus (Murayama) (Coleoptera, Curculionidae, Scolytinae) From North America https://zookeys.pensoft.net/article/2319/ ZooKeys 56: 219-226

DOI: 10.3897/zookeys.56.528

Authors: Robert Rabaglia, Milos Knizek, Wood Johnson

Abstract: Xyleborinus octiesdentatus (Murayama), an ambrosia beetle native to Asia, is reported for the first time in North America based on specimens from Alabama and Louisiana. This is the twenty-first species of exotic Xyleborina documented in North America. A re-description of the female and a key to the four North American species of Xyleborinus are presented.
