DOI: 10.3897/zookeys.914.47067

Authors: Thomas Kaltenbach, Jean-Luc Gattolliat

Abstract: Material collected between 2000 and 2014 on the island Borneo, including the Indonesian province of Kalimantan, the Malaysian province of Sabah and Brunei Darussalam, substantially increased our knowledge of Labiobaetis on this island. The total number of Labiobaetis species in Borneo increased to five, as only one species, L. borneoensis (Müller-Liebenau, 1984), was previously reported. Three new species were identified by morphology and partly by using genetic distance (COI, Kimura 2-parameter). They are described and illustrated based on their larvae (Labiobaetis bakerae sp. nov., L. penan sp. nov. and L. dayakorum sp. nov.); in one case, the imago is described as well. New reports of L. borneoensis are presented and the imago of this species is described for the first time. Labiobaetis moriharai (Müller-Liebenau, 1984), originally described from mainland Malaysia (Province Selangor), is reported from Borneo for the first time. The interspecific K2P distances in Borneo are between 19% and 25%, the intraspecific distances are usually between 0% and 1%. The total number of Labiobaetis species worldwide is augmented to 126.

A review of the Cholevinae from the island of Borneo (Coleoptera, Leiodidae) https://zookeys.pensoft.net/article/23212/ ZooKeys 777: 57-108

DOI: 10.3897/zookeys.777.23212

Authors: Menno Schilthuizen, Michel Perreau, Iva Njunjić

Abstract: The available knowledge of the round fungus beetle subfamily Cholevinae (Leiodidae) from the island of Borneo is reviewed, and the results of newly studied material presented. The currently known 30 species (of which 14 are newly described herein) represent the genera Micronemadus (one species), Catops (one species), Baryodirus (one species), Ptomaphaginus (14 species), and Ptomaphaminus (13 species). The following new species are described: Micronemadus sondaicus Schilthuizen & Perreau, sp. n., Ptomaphaginus grandis Schilthuizen & Perreau, sp. n., P. louis Schilthuizen & Perreau, sp. n., P. muluensis Schilthuizen & Perreau, sp. n., and P. isabellarossellini Schilthuizen, Njunjić & Perreau, sp. n., and Ptomaphaminus kinabatanganensis Njunjić, Schilthuizen & Perreau, sp. n., P. testaceus Schilthuizen & Perreau, sp. n., P. nanus Schilthuizen & Perreau, sp. n., P. marshalli Schilthuizen & Perreau, sp. n., P. hanskii Schilthuizen & Perreau, sp. n., P. sarawacensis Schilthuizen & Perreau, sp. n., P. layangensis Schilthuizen & Perreau, sp. n., P. microphallus Schilthuizen & Perreau, sp. n., and P. alabensis Schilthuizen & Perreau, sp. n. It is expected that the cholevine biodiversity of Borneo is still far from completely known. Nonetheless, provisional identification keys to all species known so far are presented.

Review of Dolichostyrax Aurivillius (Cerambycidae, Lamiinae) in Borneo, with descriptions of three new genera and the first case of (ovo)viviparity in the long-horned beetles https://zookeys.pensoft.net/article/7961/ ZooKeys 587: 49-75

DOI: 10.3897/zookeys.587.7961

Authors: Radim Gabriš, Robin Kundrata, Filip Trnka

Abstract: We reviewed the species of genus Dolichostyrax Aurivillius (Cerambycidae: Morimopsini) from Borneo, which included the redescriptions of two species – D. moultoni Aurivillius, 1911 and D. longipes Aurivillius, 1913, with the first female description for the latter. After the examination of the additional material previously identified as Dolichostyrax, we described three new genera – Borneostyrax gen. n., Microdolichostyrax gen. n., and Eurystyrax gen. n. Borneostyrax cristatus sp. n. was described based on the male and female specimens, whilst Microdolichostyrax hefferni sp. n., M. minutus sp. n. and Eurystyrax nemethi sp. n. are known only from females. All studied species are distributed in the mountain regions of Sabah, with the exception of D. moultoni from Sarawak. An identification key to the genera of Bornean Morimopsini and species of Dolichostyrax, Borneostyrax gen. n., Microdolichostyrax gen. n. and Eurystyrax gen. n. is provided and their distributions and intraspecific morphological variability are discussed. The short and wide ovipositor, loss of spermatheca, and presence of large larvae without apparent eggbursters inside the female abdomens indicate the presence of (ovo)viviparity in Borneostyrax gen. n. This is the first case of this rare phenomenon within Cerambycidae.

A new species of open-air processional column termite, Hospitalitermes nigriantennalis sp. n. (Termitidae), from Borneo https://zookeys.pensoft.net/article/6306/ ZooKeys 554: 27-36

DOI: 10.3897/zookeys.554.6306

Authors: Syaukani Syaukani, Graham J. Thompson, Herbert Zettel, Teguh Pribadi

Abstract: A new species of open-air processional column termite is here described based on the soldier and worker castes from eight colonies in north Barito, central Kalimantan. Hospitalitermes nigriantennalis sp. n. is readily distinguished in the field from related Hospitalitermes spp. by the light brown to orangish coloration of the soldier head capsule that, further, is with vertex yellowish and nasus brownish. The soldier antenna and the maxillary and labial palps are blackish. By contrast, soldiers from other species of Hospitalitermes from this region have a uniformly black head capsule and antennae. Finally, H. nigriantennalis sp. n. has a minute indentation in the middle of the posterior part of head capsule, which further helps to differentiate this new species from other Hospitalitermes from the Indo-Malayan and Austro-Malayan regions.

A new Chinese species of Eostrobilops Pilsbry, 1927 with a checklist of Eostrobilops and Enteroplax Gude, 1897 species (Gastropoda, Pulmonata, Strobilopsidae) https://zookeys.pensoft.net/article/5449/ ZooKeys 508: 85-95

DOI: 10.3897/zookeys.508.10004

Authors: Barna Páll-Gergely, András Hunyadi, Takahiro Asami

Abstract: Eostrobilops humicolus Páll-Gergely & Hunyadi, sp. n. is described from Guangxi Province, China. It is characterized by the combination of a small shell (diameter: 2.3–2.4 mm), strongly ribbed dorsal surface, an infraparietal lamella not reaching the callus, and long basal folds. The new species is found approximately 500 and 800 km from the two nearest species E. infrequens (northern Vietnam), and E. diodontina (Hunan, China), respectively. A checklist of extant Eostrobilops Pilsbry, 1927 and Enteroplax Gude, 1899 species is provided. Enteroplax yaeyamensis Habe & Chinen, 1974, Enteroplax kanjiokuboi Minato & Tada, 1992 and Enteroplax taiwanica Minato & Tada, 1992 are moved to the genus Eostrobilops because of the lack of an elevated parietal callus and a peripheral thread. A map showing all Eostrobilops records is provided.

A review of Bornean Micronectidae (Hemiptera, Heteroptera, Nepomorpha) with descriptions of two new species from Sabah, Malaysia1 https://zookeys.pensoft.net/article/5221/ ZooKeys 501: 27-62

DOI: 10.3897/zookeys.501.9416

Authors: Ping-ping Chen, Nico Nieser, Johnny Lapidin

Abstract: Previous research of Bornean Micronectidae Jaczewski, 1924 (pygmy water boatmen) is summarized based on the data from the literature and recent work. All the Bornean micronectids belong to the genus Micronecta Kirkaldy, 1897. Descriptions or redescriptions and a key to the eight species, which have so far been found in Borneo are presented, namely M. decorata Lundblad, 1933, M. ludibunda Breddin, 1905, M. liewi sp. n., M. lakimi sp. n., M. lumutensis Chen, Nieser & Lansbury, 2008, M. skutalis Nieser & Chen, 1999, M. kymatista Nieser & Chen, 1999) and M. quadristrigata Breddin, 1905. The synonyms are indicated under each species. To facilitate identification, illustrations and habitus photos are provided. The faunistic components of Micronectidae in Borneo are discussed from a zoogeographic point of view.

Molecular data for Crenavolva species (Gastropoda, Ovulidae) reveals the synonymy of C. chiapponii https://zookeys.pensoft.net/article/5208/ ZooKeys 501: 15-26

DOI: 10.3897/zookeys.501.9144

Authors: Bastian Reijnen

Abstract: During fieldwork in Indonesia and Malaysia, eight lots containing 33 specimens belonging to the genus Crenavolva (Ovulidae) were collected. Species were initially identified as C. aureola, C. chiapponii, C. striatula and C. trailli, respectively. For C. chiapponii this is the second record. In contrast to the ecological data available from the original description of this species, it was found in shallow water on a gorgonian host coral, i.e. Acanthogorgia sp. A molecular analysis based on COI and 16S mtDNA markers, including sequence data obtained from GenBank, showed that C. chiapponii should be considered a junior synonym of C. aureola and that previously identified ovulid specimens are probably misidentified.

On the validity of Epeorella Ulmer, 1939 (Ephemeroptera, Heptageniidae) with general considerations on the Heptageniidae of the Sunda Islands https://zookeys.pensoft.net/article/4152/ ZooKeys 445: 97-106

DOI: 10.3897/zookeys.445.8370

Authors: Michel Sartori

Abstract: The type material of Epeorella borneonia Ulmer, 1939, the sole species of the genus Epeorella Ulmer, 1939 is reinvestigated and a lectotype (male imago) is designated. Based on several morphological structures, the synonymy with Epeorus Eaton, 1881 (Rhithrogeninae) is rejected. Epeorella stat. prop., known only at the winged stages, belongs to the subfamily Ecdyonurinae, and is a probable endemic of the island of Borneo. The newly erected genus Darthus Webb & McCafferty, 2007, also endemic to Borneo and only known by one species at the nymphal stage, is shown to be a junior subjective synonym of Epeorella. The new combination Epeorella vadora (Webb & McCafferty, 2007) is proposed for the species. The distribution of known heptageniid species from the Sunda Islands is discussed.

Serendipity at the Smithsonian: The 107-year journey of Rhipidocyrtus muiri Falin & Engel, new genus and species (Ripidiinae, Ripidiini), from jungle beast to valid taxon https://zookeys.pensoft.net/article/3948/ ZooKeys 424: 101-116

DOI: 10.3897/zookeys.424.7853

Authors: Zachary Falin, Michael Engel

Abstract: The long and tortuous history of an enigmatic and rare new genus and species of ripidiine wedge beetle (Ripiphoridae: Ripidiinae: Ripidiini) from Borneo is discussed and the taxon described and figured as Rhipidocyrtus muiri Falin & Engel, gen. n. and sp. n. The holotype male, and only known specimen, was collected 107 years ago in Borneo but subsequent to this it was transferred among early researchers in the early 1900s. The specimen was dissected and many portions slide mounted, but these were disassociated from the pinned body for more than a generation. A happenstance encounter led to the rediscovery and reassociation of the body and slide-mounted abdomen and other sclerites in 2011, and to its eventual description herein. Ripidiine diversity is briefly discussed and comparisons made between Rhipidocyrtus and other members of the subfamily.

The “Fungia patella group” (Scleractinia, Fungiidae) revisited with a description of the mini mushroom coral Cycloseris boschmai sp. n. https://zookeys.pensoft.net/article/3217/ ZooKeys 371: 57-84

DOI: 10.3897/zookeys.371.6677

Authors: Bert Hoeksema

Abstract: The recent taxonomic history of extant free-living Cycloseris species is briefly reviewed, resulting in the description of Cycloseris boschmai sp. n. (Scleractinia, Fungiidae) and a discussion on the validity of two other recently described species. Some Cycloseris species were previously considered to belong to the Fungia patella group, which also concerned misidentified museum specimens that actually belong to the new species. Other specimens of C. boschmai sp. n. were photographed and collected in the course of 30 years of fieldwork. The new mushroom coral is compared with other free-living Cycloseris species by means of an identification key. With a maximum diameter of 50 mm, it is the smallest free-living mushroom coral discovered so far. It can also be distinguished by its large primary order costae and variable colouration. Its distribution range is limited to the Coral Triangle, where it can be observed as an uncommon species on lower reef slopes.

Did the genus Parandrocephalus Heller, 1916 (Coleoptera, Cerambycidae, Callichromatini) cross the Wallace line? The taxonomic status of Parandrocephalus blairi Bentanachs & Vives 2009 and a new subgenus of Hexamitodera Heller, 1896, with notes on convergent evolution and secondary sexual characters https://zookeys.pensoft.net/article/3922/ ZooKeys 293: 77-89

DOI: 10.3897/zookeys.293.5133

Authors: Robert Perger

Abstract: The genera Parandrocephalus Heller, 1916 and Hexamitodera Heller, 1896 are reviewed and redescribed. Based on the combination of chromatic sexual dimorphism, velvety pubescence on the whole dorsal body and distinctly developed carina on the elytra, Parandrocephalus blairi Bentanachs & Vives, 2009 is transferred to Hexamitodera.A new subgenus, Sulcognatha Perger, is instituted to accommodate mandible, head and metasternal modifications in H. blairi comb n.. that are lacking in the type species of Hexamitodera, H. semivelutina. As indicated by fundamental structural differences in the mandibles of Parandrocephalus and H. (Sulcognatha) blairi comb. n., the exaggerated secondary sexual traits and open procoxal cavities in both taxa are presumably the result of convergent evolution. Contrary to Bentanachs & Vives (2009), the presence of the two Parandrocephalus species in Sundaland and the endemism of Hexamitodera on Sulawesi agree well with the zoogeographical separation of both areas by the Wallace line.

Phylogeny and host-plant relationships of the Australian Myrtaceae leafmining moth genus Pectinivalva (Lepidoptera, Nepticulidae), with new subgenera and species https://zookeys.pensoft.net/article/3748/ ZooKeys 278: 1-64

DOI: 10.3897/zookeys.278.4743

Authors: Robert Hoare, Erik van Nieukerken

Abstract: The phylogeny of the mainly Australian nepticulid genus Pectinivalva Scoble, 1983 is investigated on the basis of morphology, and a division into three monophyletic subgenera is proposed on the basis of these results. These subgenera (Pectinivalva, Casanovula Hoare, subgen. n. and Menurella Hoare, subgen. n. ) are described and diagnosed, the described species of Pectinivalva are assigned to them, and representative new species are described in each: P. (P.) mystaconota Hoare, sp. n., P. (C.) brevipalpa Hoare, sp. n., P. (C.) minotaurus Hoare, sp. n., P. (M.) scotodes Hoare, sp. n., P. (M.) acmenae Hoare, sp. n., P. (M.) xenadelpha Van Nieukerken & Hoare, sp. n., P. (M.) quintiniae Hoare & Van Nieukerken, sp. n., and P. (M.) tribulatrix Van Nieukerken & Hoare, sp. n. Pectinivalva (Menurella) quintiniae (from Quintinia verdonii, Paracryphiaceae) is the first known member of the genus with a host-plant not belonging to Myrtaceae. P. (M.) xenadelpha from Mt Gunung Lumut, Kalimantan, Borneo, is the first pectinivalvine reported from outside Australia. Keys to the subgenera of Nepticulidae known from Australia, based on adults, male and female genitalia, and larvae, are presented. Host-plant relationships of Pectinivalva are discussed with relation to the phylogeny, and a list of known host-plants of Pectinivalva, including hosts of undescribed species, is presented. DNA barcodes are provided for most of the new and several unnamed species.
