Authors: Leonardo Platania, Jesús Gómez-Zurita

Abstract: The Eumolpinae leaf beetles of New Caledonia are very diverse, but our knowledge about their diversity is still incomplete. Following a renewed interest in the group in the last two decades, there has been an exponential increase in the number of species described, with species descriptions and taxonomic reassessment ongoing. In this work, the catalogue of New Caledonian Eumolpinae is updated, incorporating all these recent changes, and also indicating the collection where type specimens are currently available. The updated catalogue includes 120 species in 13 genera, and more additions and taxonomic changes, including new combinations, are expected in forthcoming years. Here two new synonymies are reported, namely Dumbea striata Jolivet, Verma & Mille, 2007 = Taophila cancellata Samuelson, 2010, syn. nov.; and Dematochroma theryi Jolivet, Verma & Mille, 2010 = Dematochroma poyensis Jolivet, Verma & Mille, 2010, syn. nov. Moreover, two species still retaining their original adscription to the genus Colaspis Fabricius, 1801, are treated as incertae sedis. This catalogue represents a useful tool for future taxonomic studies of New Caledonian Chrysomelidae and can assist biodiversity surveys and conservation studies within the archipelago.

Austrelatus gen. nov., a new genus of Australasian diving beetles (Coleoptera, Dytiscidae, Copelatinae), with the discovery of 31 new species from New Guinea https://zookeys.pensoft.net/article/103834/ ZooKeys 1170: 1-164

DOI: 10.3897/zookeys.1170.103834

Authors: Helena Shaverdo, Jiří Hájek, Lars Hendrich, Suriani Surbakti, Rawati Panjaitan, Michael Balke

Abstract: Herein, Austrelatus gen. nov. (type species: Copelatus irregularis W.J. Macleay, 1871) is described for a distinctive lineage of predominantly Australasian species previously assigned to Copelatus Erichson, 1832. The new genus was retrieved as well supported, monophyletic clade in phylogenetic analysis of DNA sequences data using Bayesian and parsimony approaches. The main morphological diagnostic character of Austrelatus is a complex median lobe of the aedeagus, with evident dorsal and ventral sclerites usually divided in apical half into two lobes of different shape or otherwise modified. Morphological comparison of the new genus with other Copelatinae genera, especially with Copelatus and Exocelina Broun, 1886, and a generic key to the New Guinean Copelatinae are provided. New combinations are established for 31 already described species mainly from the Australian Region (all from Copelatus): Austrelatus adelbert (Megna, Atthakor, Manaono, Hendrich & Balke, 2017), comb. nov.; A. badeni (Sharp, 1882), comb. nov.; A. bakewelli (J. Balfour-Browne, 1939), comb. nov.; A. baranensis (Hájek, Shaverdo, Hendrich & Balke, 2021), comb. nov.; A. bougainvillensis (Hájek, Shaverdo, Hendrich & Balke, 2021), comb. nov.; A. boukali (Hendrich & Balke, 1998), comb. nov.; A. clarki (Sharp, 1882), comb. nov.; A. daemeli (Sharp, 1882), comb. nov.; A. davidi (Wewalka, 2017), comb. nov.; A. deccanensis (Sheth, Ghate & Hájek, 2018), comb. nov.; A. fidschiensis (Zimmermann, 1928), comb. nov.; A. gestroi (Régimbart, 1892), comb. nov.; A. irregularis (W.J. Macleay, 1871), comb. nov.; A. kaszabi (Guignot, 1956), comb. nov.; A. kietensis (Hájek, Shaverdo, Hendrich & Balke, 2021), comb. nov.; A. laevipennis (Hájek, Shaverdo, Hendrich & Balke, 2021), comb. nov.; A. luteomaculatus (Guignot, 1956), comb. nov.; A. maushomi (Sheth, Ghate & Hájek, 2018), comb. nov.; A. neoguineensis (Zimmermann, 1919), comb. nov.; A. nigrolineatus (Sharp, 1882), comb. nov.; A. papuensis (J. Balfour-Browne, 1939), comb. nov.; A. parallelus (Zimmermann, 1920a), comb. nov.; A. schuhi (Hendrich & Balke, 1998), comb. nov.; A. sibelaemontis (Hájek, Hendrich, Hawlitschek & Balke, 2010), comb. nov.; A. strigosulus (Fairmaire, 1878), comb. nov.; A. ternatensis (Régimbart, 1899), comb. nov.; A. uludanuensis (Hendrich & Balke, 1995), comb. nov.; A. urceolus (Hájek, Shaverdo, Hendrich & Balke, 2021), comb. nov.; A. variistriatus (Hájek, Shaverdo, Hendrich & Balke, 2021), comb. nov.; A. wallacei (J. Balfour-Browne, 1939), comb. nov. and A. xanthocephalus (Régimbart, 1899), comb. nov. Austrelatus species from New Guinea are divided into two informal species groups, the A. neoguineensis group and A. papuensis group, and A. fumato sp. nov. and A. setiphallus sp. nov. standing aside of them. The A. neoguineensis group is introduced with three previously known species and 29 new species described here based on the morphological characters and Cox1 data: Austrelatus baliem sp. nov., A. bormensis sp. nov., A. brazza sp. nov., A. debulensis sp. nov., A. fakfak sp. nov., A. febrisauri sp. nov., A. fojaensis sp. nov., A. garainensis sp. nov., A. innominatus sp. nov., A. lembenensis sp. nov., A. lisae sp. nov., A. manokwariensis sp. nov., A. mimika sp. nov., A. mirificus sp. nov., A. moreguinensis sp. nov., A. nadjae sp. nov., A. oksibilensis sp. nov., A. pseudoneoguineensis sp. nov., A. pseudoksibilensis sp. nov., A. rajaampatensis sp. nov., A. rouaffer sp. nov., A. rugosus sp. nov., A. sandaunensis sp. nov., A. sarmiensis sp. nov., A. securiformis sp. nov., A. testegensis sp. nov., A. toricelli sp. nov., A. vagauensis sp. nov., and A. wanggarensis sp. nov. Copelatus vagestriatus Zimmermann, 1919, syn. nov. is recognised as a junior subjective synonym of A. clarki (Sharp, 1882). The lectotypes of Copelatus gestroi Régimbart, 1892, C. neoguineensis Zimmermann, 1919 and C. xanthocephalus Régimbart, 1899 are designated. All species are (re)described, and their important species characters (genitalia, habitus, and colour patterns) are illustrated. Keys to all species are provided. The known distribution and habitat preferences of each species are outlined briefly. New Guinean Austrelatus occupy a variety of stagnant water habitats, either lentic sensu stricto, or standing water associated with lotic habitats (e.g., backflows, rockpools, intermittent / ephemeral stream pools).

Seven new “cryptic” species of Discodorididae (Mollusca, Gastropoda, Nudibranchia) from New Caledonia https://zookeys.pensoft.net/article/98258/ ZooKeys 1152: 45-95

DOI: 10.3897/zookeys.1152.98258

Authors: Julie Innabi, Carla C. Stout, Ángel Valdés

Abstract: The study of a well-preserved collection of discodorid nudibranchs collected in Koumac, New Caledonia, revealed the presence of seven species new to science belonging to the genera Atagema, Jorunna, Rostanga, and Sclerodoris, although some of the generic assignments are tentative as the phylogeny of Discodorididae remains unresolved. Moreover, a poorly known species of Atagema originally described from New Caledonia is re-described and the presence of Sclerodoris tuberculata in New Caledonia is confirmed with molecular data. All the species described herein are highly cryptic on their food source and in the context of the present study the term “cryptic” is used to denote such species. This paper highlights the importance of comprehensive collecting efforts to identify and document well-camouflaged taxa.

Three new species of Nautilus Linnaeus, 1758 (Mollusca, Cephalopoda) from the Coral Sea and South Pacific https://zookeys.pensoft.net/article/84427/ ZooKeys 1143: 51-69

DOI: 10.3897/zookeys.1143.84427

Authors: Gregory J. Barord, David J. Combosch, Gonzalo Giribet, Neil Landman, Sarah Lemer, Job Veloso, Peter D. Ward

Abstract: Nautiloids are a charismatic group of marine molluscs best known for their rich fossil record, but today they are restricted to a handful of species in the family Nautilidae from around the Coral Triangle. Recent genetic work has shown a disconnect between traditional species, originally defined on shell characters, but now with new findings from genetic structure of various Nautilus populations. Here, three new species of Nautilus from the Coral Sea and South Pacific region are formally named using observations of shell and soft anatomical data augmented by genetic information: N. samoaensis sp. nov. (from American Samoa), N. vitiensis sp. nov. (from Fiji), and N. vanuatuensis sp. nov. (from Vanuatu). The formal naming of these three species is timely considering the new and recently published information on genetic structure, geographic occurrence, and new morphological characters, including color patterns of shell and soft part morphology of hood, and will aid in managing these possibly endangered animals. As recently proposed from genetic analyses, there is a strong geographic component affecting taxonomy, with the new species coming from larger island groups that are separated by at least 200 km of deep water (greater than 800 m) from other Nautilus populations and potential habitats. Nautilid shells implode at depths greater than 800 m and depth therefore acts as a biogeographical barrier separating these species. This isolation, coupled with the unique, endemic species in each locale, are important considerations for the conservation management of the extant Nautilus species and populations.

Three new deep-sea species of Marphysa (Annelida, Eunicida, Eunicidae) from Papua New Guinea (Bismarck and Solomon seas) https://zookeys.pensoft.net/article/89990/ ZooKeys 1122: 81-105

DOI: 10.3897/zookeys.1122.89990

Authors: Nicolas Lavesque, Guillemine Daffe, Christopher Glasby, Stéphane Hourdez, Pat Hutchings

Abstract: Three new species of Marphysa Quatrefages, 1866, Marphysa banana sp. nov., Marphysa papuaensis sp. nov., and Marphysa zanolae sp. nov. are described from deep-sea sunken vegetation off Papua New Guinea, using both morphology and molecular data (for two species). With the presence of compound spinigers only and the branchiae present over many chaetigers, Marphysa banana sp. nov. belongs to the group B2. This species is characterised by the presence of eyes, the presence of branchiae starting from chaetiger 20, and by the presence of three types of pectinate chaetae and bidentate subacicular hooks starting from chaetigers 13–52. With the presence of compound falcigers only and the branchiae restricted to a short anterior region, Marphysa papuaensis sp. nov. belongs to the group C1. This species has a bilobed prostomium but no eyes, has branchiae from chaetigers 7 to 14–16 with up to 16 filaments. Marphysa papuaensis sp. nov. is also characterised by the presence of bidentate subacicular hooks from chaetiger 20 and by a single type of pectinate chaetae. Finally, Marphysa zanolae sp. nov. belongs to the group C2, with the presence of compound falcigers only and the branchiae present over many chaetigers. This species is characterised by the absence of eyes, by the presence of branchiae with a single long filament starting from chaetiger 31, by unidentate subacicular hooks starting from chaetiger 28 and finally by one type of pectinate chaetae with very long outer teeth.

Battle of the bands: systematics and phylogeny of the white Goniobranchus nudibranchs with marginal bands (Nudibranchia, Chromodorididae) https://zookeys.pensoft.net/article/72939/ ZooKeys 1083: 169-210

DOI: 10.3897/zookeys.1083.72939

Authors: Giun Yee Soong, Lynn J. Bonomo, James D. Reimer, Terrence M. Gosliner

Abstract: Species identities of Goniobranchus nudibranchs with white bodies and various marginal bands have long been problematic. In this study, specimens of these Goniobranchus nudibranchs from the Philippines, Peninsular Malaysia, Japan, Papua New Guinea, and Madagascar were analyzed and molecular data were obtained in order to re-examine the relationships between species within this “white Goniobranchus with marginal bands” group. The analyses clearly recovered six species groups corresponding to the described species Goniobranchus albonares, G. preciosus, G. rubrocornutus, G. sinensis, and G. verrieri as well as one new species, G. fabulus Soong & Gosliner, sp. nov. Notably, G. preciosus, G. sinensis, G. rubrocornutus, G. verrieri, and G. fabulus Soong & Gosliner, sp. nov. exhibit color variation and polymorphism, suggesting that some aspects of color patterns (e.g., presence or absence of dorsal spots) may not always be useful in the identification of species in the “white Goniobranchus with marginal bands” group, whereas other features such as gill and rhinophore colors and the arrangement and colors of the mantle marginal bands are more diagnostic for each species.

A new Diancta species of the family Diplommatinidae (Cyclophoroidea) from Vanua Levu Island, Fiji https://zookeys.pensoft.net/article/73241/ ZooKeys 1073: 1-12

DOI: 10.3897/zookeys.1073.73241

Authors: Estée Bochud, David Haberthür, Ruslan Hlushchuk, Eike Neubert

Abstract: A new species of Diancta of the staircase snail family Diplommatinidae is described from Mt. Savusavu, Vanua Levu Island, Fiji. Due to its left coiling shell and a constriction before the last whorl, it is placed in the genus Diancta. Micro-CT imaging reveals two apertural teeth and an inner lamella that is situated at the zone of constriction. The shell abruptly changes coiling direction by 45 degrees before the last whorl. Up to now, this coiling modus had not yet been documented for any species of Diplommatinidae from the Fiji Islands.

Resolving a century-old case of generic mistaken identity: polyphyly of Chitoniscus sensu lato resolved with the description of the endemic New Caledonia Trolicaphyllium gen. nov. (Phasmatodea, Phylliidae) https://zookeys.pensoft.net/article/66796/ ZooKeys 1055: 1-41

DOI: 10.3897/zookeys.1055.66796

Authors: Royce T. Cumming, Stephane Le Tirant, Thies H. Büscher

Abstract: With every molecular review involving Chitoniscus Stål, 1875 sensu lato samples from Fiji and New Caledonia revealing polyphyly, the morphology from these two distinct clades was extensively reviewed. Morphological results agree with all previously published molecular studies and therefore Trolicaphyllium gen. nov. is erected to accommodate the former Chitoniscus sensu lato species restricted to New Caledonia, leaving the type species Chitoniscus lobiventris (Blanchard, 1853) and all other Fijian species within Chitoniscus sensu stricto. Erection of this new genus for the New Caledonian species warrants the following new combinations: Trolicaphyllium brachysoma (Sharp, 1898), comb. nov., Trolicaphyllium erosus (Redtenbachher, 1906), comb. nov., and Trolicaphyllium sarrameaense (Größer, 2008a), comb. nov. Morphological details of the female, male, freshly hatched nymph, and egg are illustrated and discussed alongside the Chitoniscus sensu stricto in order to differentiate these two clades which have been mistaken as one for decades.

Phylogenetic systematics of the genera of Thryptocerina Jeannel, 1949 and new species from New Caledonia (Coleoptera, Carabidae, Oodini) https://zookeys.pensoft.net/article/63775/ ZooKeys 1044: 375-425

DOI: 10.3897/zookeys.1044.63775

Authors: Kipling Will, Borislav Guéorguiev

Abstract: The Oodini precinctive to New Caledonia are reviewed with nine species recognized, of which seven are newly described in two genera. Five species are described in the genus Coptocarpus Chaudoir: C. microps sp. nov., C. erwini sp. nov., C. amieuensis sp. nov., C. magnus sp. nov., and C. lescheni sp. nov. In the genus Adelopomorpha Heller two species, A. tethys sp. nov. and A. tuberculata sp. nov., are described. In order to place cladistically the newly described species in a genus, a phylogenetic analysis of a matrix of 36 characters of adult morphology was conducted including exemplar species of three putative outgroup genera, six putative ingroup thryptocerine oodine genera, and all oodine species from New Caledonia. Results show support for Thryptocerina and monophyly of Adelopomorpha. Hoplolenus LaFerté-Sénectère is not monophyletic and Hoplolenus cyllodinus Fauvel is newly combined as Coptocarpus cyllodinus comb. nov. New Caledonian species of Coptocarpus form a clade, but the Australian species of the genus included in the analysis are rendered paraphyletic by African and Malagasy genera. Implications of this preliminary study for the classification of Oodini and trends in the evolution of the female reproductive tract are discussed. A key to the New Caledonian species of Oodini is provided.

Seven new species of the Exocelina ekari group from New Guinea central and coastal mountains (Coleoptera, Dytiscidae, Copelatinae) https://zookeys.pensoft.net/article/61554/ ZooKeys 1026: 45-67

DOI: 10.3897/zookeys.1026.61554

Authors: Helena Shaverdo, Suriani Surbakti, Bob Sumoked, Michael Balke

Abstract: Seven new species of the genus Exocelina Broun, 1886 are described from three different mountain ranges of New Guinea: E. foja sp. nov., E. riberai sp. nov., E. apistefti sp. nov., and E. waaf sp. nov. from the Foja Mountains; E. hudsoni sp. nov. from the Cyclops Mountains; E. ekpliktiki sp. nov. and E. oraia sp. nov. from Wano Land. All of them are placed into the E. ekari group based on the structure of their male genitalia. The species are characteristic dytiscid elements of the fauna of northern cost and the western part of central orogen of New Guinea. Two taxonomic notes are presented: Exocelina athesphati is a correct name for the recently described Exocelina athesphatos Shaverdo et al., 2020; Exocelina bacchus Balke, nom. nov. is a replacement name for Exocelina bacchusi (Balke, 1998), formerly Copelatus (Papuadytes) bacchusi Balke, 1998, a junior homonym of Copelatus bacchusi Wewalka, 1981.

Two new species of the Exocelina ekari group from New Guinea with strongly modified male antennae (Coleoptera, Dytiscidae, Copelatinae) https://zookeys.pensoft.net/article/55007/ ZooKeys 960: 63-78

DOI: 10.3897/zookeys.960.55007

Authors: Helena Shaverdo, Suriani Surbakti, Bob Sumoked, Michael Balke

Abstract: Two new species of the genus Exocelina Broun, 1886: E. athesphatos sp. nov. and E. tsinga sp. nov. are described from New Guinea and placed into the E. ekari group based on the structure of their male genitalia. The two species are very similar with respect to their external morphology and characterised by almost identical, strongly modified male antennae. However, they can easily be separated by the shape and setation of the median lobe and paramere. Based on morphological similarity and results of a molecular phylogenetic analysis, we suggest these are sister species. Both of them have been collected on the southern slopes of the Central Range (the spine of New Guinea), with a distance of ca. 380 km straight line between the collecting localities.

Twenty-six new species of Hoploscopa (Lepidoptera, Crambidae) from South-East Asia revealed by morphology and DNA barcoding https://zookeys.pensoft.net/article/36563/ ZooKeys 907: 1-99

DOI: 10.3897/zookeys.907.36563

Authors: Théo Léger, Christian Kehlmaier, Charles S. Vairappan, Matthias Nuss

Abstract: Hoploscopa Meyrick (Lepidoptera: Crambidae) is a fern-feeding genus found in montane areas of South-East Asia and Melanesia, eastwards up to the Samoan Islands. It includes sixteen described species, with at least 70 further undescribed species known from scientific collections. An iterative approach including morphological and molecular characters was used in order to explore the diversity of Hoploscopa. The hitherto described species are revised, and descriptions authored by T. Léger and M. Nuss are provided for an additional 26 new species: H. agtuuganonensis sp. nov., H. albipuncta sp. nov., H. albomaculata sp. nov., H. anacantha sp. nov., H. boleta sp. nov., H. cynodonta sp. nov., H. danaoensis sp. nov., H. gombongi sp. nov., H. gracilis sp. nov., H. ignitamaculae sp. nov., H. isarogensis sp. nov., H. jubata sp. nov., H. kelama sp. nov., H. kinabaluensis sp. nov., H. mallyi sp. nov., H. marijoweissae sp. nov., H. matheae sp. nov., H. niveofascia sp. nov., H. pangrangoensis sp. nov., H. parvimacula sp. nov., H. pseudometacrossa sp. nov., H. sepanggi sp. nov., H. sumatrensis sp. nov., H. titika sp. nov., H. tonsepi sp. nov., H. ypsilon sp. nov. Using a protocol specific for the amplification of DNA from old museum specimens, we recovered 101 COI barcodes for all but one of the newly described species, with 76 being barcode compliant (>487 bp). Species delimitation analyses suggest cryptic diversity, with six cases reflecting allopatric divergence, and two further cases found in sympatry.

A new species in the genus Acartia Dana, 1846 (Crustacea, Copepoda, Calanoida, Acartiidae) from the South Pacific coastal waters of Nadi Bay, Fiji https://zookeys.pensoft.net/article/38369/ ZooKeys 893: 69-89

DOI: 10.3897/zookeys.893.38369

Authors: Seunghan Lee, Ho Young Soh, Wonchoel Lee

Abstract: A new species in the genus Acartia, Acartia nadiensis sp. nov., is described from Fijian coastal waters. This species belongs to the subgenus Odontacartia based on the following morphological features: presence of a rostral filaments, a pointed process on the last prosomite, a serrated terminal spine on female P5, and the absence of a protrusion on the basis of the male right P5. This new species can be differentiated from its congeners by the combination of the absence of a spine on the first segment of the antennules, the short outer seta of female P5, and a medial spine on the exp-2 of the left male P5. Phylogenetic analyses using mitochondrial COI partial sequences show that the new species is distinct from its congeners.

Nine new species groups, 15 new species, and one new subspecies of New Guinea diving beetles of the genus Exocelina Broun, 1886 (Coleoptera, Dytiscidae, Copelatinae) https://zookeys.pensoft.net/article/37403/ ZooKeys 878: 73-143

DOI: 10.3897/zookeys.878.37403

Authors: Helena Shaverdo, Suriani Surbakti, Evie L. Warikar, Katayo Sagata, Michael Balke

Abstract: Nine new species groups of Exocelina Broun, 1886 from New Guinea are introduced with keys to their representatives. Four groups are monotypic and include three new species: the E. aipomek group, the E. koroba group: E. koroba sp. nov., the E. mekilensis group: E. mekilensis sp. nov., and the E. morobensis group: E. morobensis sp. nov. The remaining five species groups include 18 species with 12 new species and one new subspecies: the E. bacchusi group: E. akameku sp. nov., E. oiwa sp. nov., E. oksibilensis sp. nov., and E. bacchusi herzogensis ssp. nov.; the E. jaseminae group: E. aseki sp. nov., E. kailaki sp. nov., and E. pseudojaseminae sp. nov.; the E. larsoni group: E. warahulenensis sp. nov.; the E. takime group: E. mianminensis sp. nov.; and the E. warasera group: E. haia sp. nov., E. kobau sp. nov., E. pulchella sp. nov., and E. warasera sp. nov. Diagnoses of five already described species of these groups are provided, as well as comparatives notes on all species. Exocelina santimontis (Balke, 1998) syn. nov. is a junior synonym of E. aipomek (Balke, 1998). Data on the distribution of the species are given, showing that most of the species of these groups occur in the Papua New Guinea.

Scolopsis lacrima, a new species of monocle bream (Teleostei, Perciformes, Nemipteridae) from New Caledonia https://zookeys.pensoft.net/article/35052/ ZooKeys 861: 119-128

DOI: 10.3897/zookeys.861.35052

Authors: Jumpei Nakamura, Philippe Béarez, Hiroyuki Motomura

Abstract: The new monocle bream Scolopsis lacrima sp. nov. is described from a single specimen (213.6 mm standard length) collected from Grande-Terre Island, New Caledonia. The new species closely resembles S. meridiana, both species having the upper part of the pectoral-fin base with reddish blotch when fresh, two bands across the top of the snout, a dorsal scaled area on the head reaching anteriorly to between the anterior margin of the eye and anterior nostril, a similar number of lateral-line scales, and absence of a small antrorse spine below the eye. However, S. lacrima sp. nov. is distinguished from S. meridiana by having diagonal lines on the body absent (vs. 18–20 diagonal lines in the latter), a dark longitudinal band below the lateral line (vs. longitudinal lines absent), the caudal fin central area not patterned (vs. with several dark horizontal lines), a narrower body and shallower caudal peduncle.

The incredible diversity of Labiobaetis Novikova & Kluge in New Guinea revealed by integrative taxonomy (Ephemeroptera, Baetidae) https://zookeys.pensoft.net/article/28988/ ZooKeys 804: 1-136

DOI: 10.3897/zookeys.804.28988

Authors: Thomas Kaltenbach, Jean-Luc Gattolliat

Abstract: Material collected between 1999 and 2011 in Papua New Guinea and the Papua Province of Indonesia unveiled the enormous diversity of Labiobaetis on this island. Twenty-six new species were identified and delimited by integrative taxonomy using genetic distance (COI, Kimura-2-parameter) and morphology. These new species are described and illustrated based on larvae, augmenting the total number of Labiobaetis species on the island of New Guinea to 32. Seven morpho-groups of species are proposed based on morphological characters and a key to all New Guinea species is provided. The generic attributes of the larvae are summarised and slightly modified based on the examinations of the new species. Results on the genetics of most species (COI) are also provided. The interspecific K2P distances are between 13% and 32%, the intraspecific distances usually between 0% and 2%. Possible reasons for the remarkable richness of this genus in New Guinea are discussed.

Abstract: Nineteen new species of Exocelina Broun, 1886 from New Guinea are described herein: E. adelbertensis sp. n., E. ambua sp. n., E. bewani sp. n., E. cyclops sp. n., E. ibalimi sp. n., E. keki sp. n., E. kumulensis sp. n., E. mendiensis sp. n., E. menyamya sp. n., E. okapa sp. n., E. piusi sp. n., E. pseudofume sp. n., E. pseudopusilla sp. n., E. pusilla sp. n., E. sima sp. n., E. simbaiensis sp. n., E. simbaijimi sp. n., E. sumokedi sp. n., and E. yoginofi sp. n. All of them, together with five already described species, have been united into the newly defined casuarina-group, a polyphyletic complex of related species with similar shape of the median lobe and paramere setation. An identification key to all known species of the group is provided, and important diagnostic characters (habitus, color, male protarsomeres 4–5, median lobes, and parameres) are illustrated. Data on the distribution of the species are given, showing that most of the species occur in the central, mountain part of Papua New Guinea.

A new species of frog-biting midge from Papua New Guinea with a key to the described Corethrellidae of the Australopapuan region (Diptera, Corethrellidae, Corethrella) https://zookeys.pensoft.net/article/28543/ ZooKeys 795: 39-48

DOI: 10.3897/zookeys.795.28543

Authors: Gunnar Mikalsen Kvifte, Ximena E. Bernal

Abstract: Corethrella oppositophila Kvifte & Bernal, sp. n. is described based on one male and six female specimens collected at 2200 m a.s.l. on Mount Wilhelm, Papua New Guinea. The species is the fourth species of frog-biting midge described from this country and appears similar to Corethrella solomonis Belkin based on pigmentation of legs and abdominal tergites. It differs from C. solomonis, however, in the shape of female flagellomeres I–III, and in the thorax which has a dark brown vertical stripe. The new species is named for its sexually dimorphic flagellomeres, which are short and squat in the female and elongate in the male. These differences in morphological characters are discussed in light of the likely sexual differences in functional uses of the antennae, as males use them for mating only whereas females use them both for mating and prey location. An emended key is presented to the described Australopapuan species of Corethrellidae.

Doubling the known endemic species diversity of New Caledonian armored scale insects (Hemiptera, Diaspididae) https://zookeys.pensoft.net/article/27938/ ZooKeys 782: 11-47

DOI: 10.3897/zookeys.782.27938

Authors: Nate B. Hardy, Douglas J. Williams

Abstract: Fourteen species of armored scale insects are known only from New Caledonia. Here, the adult female of fourteen more are described: Agrophaspis ansevatae sp. n., Aonidia montikoghis sp. n., Aonidia pauca sp. n., Fernaldanna whita sp. n., Furcaspis costulariae sp. n., Greeniella casuarinae sp. n., Greeniella dacrydiae sp. n., Lepidosaphes monticola sp. n., Leptaspis pege gen. et sp. n., Leucaspis montikoghis sp. n., Melanaspis nothofagi sp. n., Neomorgania nothofagi sp. n., Pseudaonidia dugdali sp. n., and Pseudaonidia yateensis sp. n. We note that the diversity of New Caledonian armored scale insects appears to have resulted more from trans-oceanic dispersal than in situ speciation.

Insights on the genus Acronymolpus Samuelson with new synonymies and exclusion of Stethotes Baly from the fauna of New Caledonia (Coleoptera, Chrysomelidae, Eumolpinae) https://zookeys.pensoft.net/article/13582/ ZooKeys 720: 65-75

DOI: 10.3897/zookeys.720.13582

Authors: Jesús Gómez-Zurita

Abstract: In this work, several taxonomic problems affecting the recently erected genus Acronymolpus Samuelson, 2015, endemic to New Caledonia, are addressed. Two of the three New Caledonian species described in Stethotes Baly are transferred to Acronymolpus and their priority is recognized over the names proposed in the revision of this genus. Moreover, different forms of Acronymolpus always found in sympatry, one reddish and larger, and the other black and smaller, were each given species status in that revision, but they are recognized here as the females and males, respectively, of the same species. The taxonomic summary of these discoveries is: (i) A. bertiae (Jolivet, Verma & Mille, 2007), comb. n. = A. meteorus Samuelson, 2015, syn. n., and A. turbo Samuelson, 2015, syn. n.; and (ii) A. jourdani (Jolivet, Verma & Mille, 2013), comb. n. = A. gressitti Samuelson, 2015, syn. n., and A. joliveti Samuelson, 2015, syn. n. New distribution data and the male genitalia and the spermatheca of the two valid species of Acronymolpus are described for the first time with reference to taxonomically important characters. Finally, the last New Caledonian species described in Stethotes is recognized here as a member of the endemic genus Taophila Heller: T. mandjeliae (Jolivet, Verma & Mille, 2010), comb. n.

DOI: 10.3897/zookeys.623.10272

Authors: Peter K. L. Ng, Chistopher Meyer

Abstract: The pea crab genus Serenotheres Ahyong & Ng, 2005 (Pinnotheridae) is currently only represented by one species, S. besutensis (Serène, 1967). A new species is now assigned to this genus, described from a date mussel Leiosolenus obesus Carpenter, 1857 (Mollusca: Bivalvia: Mytilidae: Lithophaginae) collected in the Solomon Islands. Serenotheres janus sp. n. differs from S. besutensis in possessing a conspicuously broader carapace, with the lateral margins of the dorsal lamellum distinctly produced and the posterolateral part deeply concave, the dorsal lamellum being highest at the median cleft, the rostrum is relatively more prominent, the surfaces of the anterolateral margin and hepatic region are less prominently pitted and eroded, the ischiomerus of the third maxilliped is relatively more rectangular, and the P2 merus is proportionately longer.

Abstract: Ten new species of Exocelina Broun, 1886 from New Guinea are described: E. andakombensis sp. n., E. garaina sp. n., E. injiensis sp. n., E. kabwumensis sp. n., E. marawaga sp. n., E. posmani sp. n., E. tekadu sp. n., E. varirata sp. n., E. wareaga sp. n., and E. woitapensis sp. n. All of them together with five already described species are united into the newly defined E. danae-group (with E. miriae-subgroup), a polyphyletic complex of related species with lateral setation on the median lobe. In the light of newly available material, all previously described species of the E. rivulus-group are considered to belong to a single species, E. damantiensis (Balke, 1998), which is now placed into the E. danae-group, and three new synonyms are therefore proposed: E. madangensis (Balke, 2001) syn. n., E. patepensis (Balke, 1998) syn. n., and E. rivulus (Balke, 1998) syn. n. Exocelina tarmluensis (Balke, 1998) syn. n. is a junior synonym of E. danae (Balke, 1998). Redescription of E. atratus (Balfour-Browne, 1939) is provided based on its type material. An identification key to all known species of the group is provided, and important diagnostic characters are illustrated. Data on the species distribution are given, showing that whilst most species are local endemics, E. damantiensis is extremely widely distributed.

Conflict of mitochondrial phylogeny and morphology-based classification in a pair of freshwater gastropods (Caenogastropoda, Truncatelloidea, Tateidae) from New Caledonia https://zookeys.pensoft.net/article/9144/ ZooKeys 603: 17-32

DOI: 10.3897/zookeys.603.9144

Authors: Marlen Becker, Susan Zielske, Martin Haase

Abstract: Morphological classification and mitochondrial phylogeny of a pair of morphologically defined species of New Caledonian freshwater gastropods, Hemistomia cockerelli and H. fabrorum, were incongruent. We asked whether these two nominal species can be unambiguously distinguished based on shell morphology or whether the taxonomic discrepancy inferred from these character types was reflected in the variation of shell morphology. Our investigations were based on phylogenetic analyses of a fragment of the mitochondrial cytochrome c oxidase subunit I, geometric morphometric analyses as well as micro computer tomography. The species presorted to morphospecies by eye overlapped in shell shape. However, statistically, all shells were correctly assigned, but not all of them significantly. Qualitatively, both nominal species can be unambiguously distinguished by the presence/absence of a prominent denticle within the shell. In the phylogenetic analyses, individuals from three populations clustered with the “wrong” morphospecies. In the absence of data from multiple loci, it was assumed for the single specimen from one of these populations that its misplacement was due to a recent hybridization event, based on its very shallow position in the tree. For the other two cases of misplacement neither introgression nor incomplete lineage sorting could be ruled out. Further investigations have to show whether the morphological overlap has a genetic basis or is due to phenotypic plasticity. In conclusion, despite their partly unresolved relationships H. cockerelli and H. fabrorum may be considered sister species, which are reliably diagnosable by the presence or absence of the denticle, but have not yet fully differentiated in all character complexes investigated.

DOI: 10.3897/zookeys.568.6872

Authors: Valter Weijola, Stephen Donnellan, Christer Lindqvist

Abstract: We describe a new species of Varanus from Mussau Island, north-east of New Guinea. The new species is a member of the Varanus indicus species group and is distinguished from all other members by both morphological and molecular genetic characters. It is the third species of Varanus reported from the Bismarck Archipelago and the first record of a yellow tongued member of the Varanus indicus species group from a remote oceanic island. The herpetofauna of Mussau Island has not been well studied but the discovery of this new species is in accordance with recent findings indicating that the island may harbor several unknown endemic vertebrates. The distribution of the closely related Varanus finschi is also discussed in the light of recent fieldwork and a review of old records.

DOI: 10.3897/zookeys.562.6052

Authors: Paul Oliver, Stephen Richards, Mumpuni Mumpuni, Herbert Rösler

Abstract: The diverse biota of New Guinea includes many nominally widespread species that actually comprise multiple deeply divergent lineages with more localised histories of evolution. Here we investigate the systematics of the very large geckos of the Cyrtodactylus novaeguineae complex using molecular and morphological data. These data reveal two widespread and divergent lineages that can be distinguished from each other, and from type material of Cyrtodactylus novaeguineae, by aspects of size, build, coloration and male scalation. On the basis of these differences we describe two new species. Both have wide distributions that overlap extensively in the foothill forests of the North Papuan Mountains, however one is seemingly restricted to hill and lower montane forests on the ranges themselves, while the other is more widespread throughout the surrounding lowlands. The taxon endemic to the North Papuan Mountains is related to an apparently lowland form currently known only from Waigeo and Batanta Island far to the west – hinting at a history on island arcs that accreted to form the North Papuan Mountains.

Abstract: Paranastatus Masi, 1917 (Eupelmidae, Eupelminae) was originally described based on two species from Seychelles: P. egregius and P. violaceus. Eady (1956) subsequently described P. nigriscutellatus and P. verticalis from Fiji. Here, four new species of Paranastatus are described: P. bellus Scallion, sp. n. and P. pilosus Scallion, sp. n. from Indonesia, and P. halko Scallion, sp. n. and P. parkeri Scallion, sp. n. from Fiji. A key to all Paranastatus species based on females is included and lectotypes are designated for P. egregius and P. violaceus. Finally, previously unobserved colour variation from newly collected material of P. verticalis, distribution patterns of species, and possibilities for future research are discussed.

Review of New Caledonian species of Oxyethira Eaton, with description of 17 new species, and new records for Hydroptila Dalman and Hellyethira Neboiss (Trichoptera, Hydroptilidae) https://zookeys.pensoft.net/article/6047/ ZooKeys 530: 37-90

DOI: 10.3897/zookeys.530.6047

Authors: Alice Wells, Kjell Arne Johanson

Abstract: New Caledonian representation of the cosmopolitan genus Oxyethira Eaton is reviewed, with the description of new species bringing to 26 the total for the genus on the island. The species are referred to three subgenera: Trichoglene Neboiss (11 species), Pacificotrichia Kelley (13 species) and Dampfitrichia Ulmer (one species) and one species is unplaced to subgenus. A key is provided to Oxyethira species of New Caledonia. In addition, new records are given for two otherwise Australian species, Hydroptila losida Mosely and Hellyethira malleoforma Wells. Points marked on a series of small maps of New Caledonia indicate the site or sites at which the species were collected. This final paper in a series of generic revisions brings the hydroptilid fauna of the island of New Caledonia to 60 species, distributed in six genera.

Five new cryptic freshwater gastropod species from New Caledonia (Caenogastropoda, Truncatelloidea, Tateidae) https://zookeys.pensoft.net/article/6066/ ZooKeys 523: 63-87

DOI: 10.3897/zookeys.523.6066

Authors: Martin Haase, Susan Zielske

Abstract: During the course of a project aiming at the reconstruction of the colonization of the South Pacific islands by tateid gastropods based on molecular data we discovered five new species on New Caledonia belonging to the genera Hemistomia and Leiorhagium, respectively. We describe these species based on morphological, anatomical and genetic data. All five species are morphologically cryptic as they closely resemble or are even indistinguishable from known species stressing the importance of a comprehensive taxonomic approach integrating several methods. As a consequence of their small and fragmented geographic ranges and the rapidly progressing anthropogenic land cover changes on New Caledonia, all five species qualify as critically endangered according to the criteria of the IUCN.

The Diplommatinidae of Fiji – a hotspot of Pacific land snail biodiversity (Caenogastropoda, Cyclophoroidea) https://zookeys.pensoft.net/article/4881/ ZooKeys 487: 1-85

DOI: 10.3897/zookeys.487.8463

Authors: Eike Neubert, Philippe Bouchet

Abstract: The minute (adult size 1.3–4.8 mm) land snail species of the family Diplommatinidae in the Fiji archipelago are revised based on historical material and modern (1998–99) collections targeting limestone outcrops on the largest island, Viti Levu, and several smaller islands in the Lau group. The forty-two species (including 30 new species) belong to the genera Moussonia Semper, 1865, Palaina Semper, 1865 and Diancta Martens, 1867, which are briefly characterized and keyed. The diagnostic structure of the inner lamellar system of each species is illustrated. All species except one are endemic to Fiji. In Viti Levu, the 12 localities surveyed each had 1–13 (average 5) species of Diplommatinidae; ten species were each found at a single site only. In the Lau islands, five islands were visited, with 1–4 species per island; four species are known from single islands. The number of historically known species not recollected in 1998–99 (7 species), the number of single-site occurrences (14 species), and the numerous islands — including limestone islands — that have not been surveyed at all, indicate that the 42 species of Diplommatinidae currently known from Fiji represent perhaps only half of the Fiji diplommatinid fauna. Such numbers approach the diplommatinid diversity of Palau (39 described and more than 60 undescribed species), and surpasses by far the diversity of other South Pacific archipelagos of comparable land area (New Caledonia, Vanuatu, Samoa). Nomenclatural acts: Lectotypes designated: Diplommatina fuscula, D. fuscula var. vitiana, D. godeffroyana, D. godeffroyana var. latecostata, D. tuberosa, D. martensi var. macrostoma, all Mousson, 1870. Neotypes designated: Diplommatina subregularis, D. ascendens, D. quadrata, all Mousson, 1870. New species: Diancta aurea sp. n., Diancta aurita sp. n., Diancta basiplana sp. n., Diancta controversa sp. n., Diancta densecostulata sp. n., Diancta dextra sp. n., Diancta dilatata sp. n., Diancta distorta sp. n., Diancta pulchella sp. n., Diancta rotunda sp. n., Diancta subquadrata sp. n., Diancta trilamellata sp. n., Moussonia acuta sp. n., Moussonia barkeri sp. n., Moussonia brodieae sp. n., Moussonia longipalatalis sp. n., Moussonia minutissima sp. n., Moussonia obesa sp. n., Moussonia polita sp. n., Moussonia uncinata sp. n., Moussonia vitianoides sp. n., Palaina alberti sp. n., Palaina flammulata sp. n., Palaina glabella sp. n., Palaina kitteli sp. n., Palaina labeosa sp. n., Palaina parietalis sp. n., Palaina sulcata sp. n., Palaina truncata sp. n., Palaina tuberosissima sp. n.

Revision of the ant genus Proceratium Roger (Hymenoptera, Proceratiinae) in Fiji https://zookeys.pensoft.net/article/4573/ ZooKeys 475: 97-112

DOI: 10.3897/zookeys.475.8761

Authors: Francisco Hita Garcia, Eli M. Sarnat, Evan P. Economo

Abstract: The Fiji archipelago harbours a surprisingly diverse and endemic ant fauna, despite its isolated and remote location in the South Pacific. The ant genus Proceratium is present on Fiji with three endemic species, of which P. oceanicum De Andrade, 2003 and P. relictum Mann, 1921 were previously known. In this study we describe the third species: P. vinaka sp. n. All three species are members of the widespread and species-rich P. silaceum clade. In order to integrate the new species into the current taxonomic system, we present an illustrated identification key to the worker caste of the three Fijian species. In addition, we provide a detailed description of P. vinaka, as well as species accounts for the other two species, which include diagnoses, taxonomic discussions, specimen photographs, and a distribution map.

Southern hemisphere deep-water stylasterid corals including a new species, Errina labrosa sp. n. (Cnidaria, Hydrozoa, Stylasteridae), with notes on some symbiotic scalpellids (Cirripedia, Thoracica, Scalpellidae) https://zookeys.pensoft.net/article/4510/ ZooKeys 472: 1-25

DOI: 10.3897/zookeys.472.8547

Authors: Daniela Pica, Stephen D. Cairns, Stefania Puce, William A. Newman

Abstract: A number of stylasterid corals are known to act as host species and create refuges for a variety of mobile and sessile organisms, which enhances their habitat complexity. These include annelids, anthozoans, cirripeds, copepods, cyanobacteria, echinoderms, gastropods, hydroids and sponges. Here we report the first evidence of a diverse association between stylasterids and scalpellid pedunculate barnacles and describe a new stylasterid species, Errina labrosa, from the Tristan da Cunha Archipelago. Overall, five stylasterid species are found to host eight scalpellid barnacles from several biogeographic regions in the southern hemisphere (Southern Ocean, temperate South America and the southern Indo-Pacific realms). There is an apparent lack of specificity in this kind of association and different grades of reaction to the symbiosis have been observed in the coral. These records suggest that the association between pedunculate barnacles and hard stylasterid corals has a wide distribution among different biogeographic realms and that it is relatively rare and confined largely to deep water.

First record of the genus Wilkinsonellus (Hymenoptera, Braconidae, Microgastrinae) from Fiji with description of three new species https://zookeys.pensoft.net/article/3688/ ZooKeys 397: 25-47

DOI: 10.3897/zookeys.397.7195

Authors: Diana Arias, Yali Zhang, James Whitfield

Abstract: Wilkinsonellus Mason is a relatively small Pantropical genus of braconid parasitoid wasps within the subfamily Microgastrinae. Most of the currently described species are from the Palaeotropics; however, previous records were absent from Fiji. Here, the first three Wilkinsonellus species from Fiji are described: Wilkinsonellus corpustriacolor sp. n., Wilkinsonellus fijienis sp. n. and Wilkinsonellus nescalpura sp. n. The material was collected by Malaise traps set up in a quite variety of ecosystems (wet zone, dry zone and coastal forests) throughout the archipelago. With these records, Fiji represents the easternmost known distribution of the genus in the Indo-Pacific Region. A key to all of the currently known Wilkinsonellus species is included to facilitate species identification.

A new genus of metalmark moths (Lepidoptera, Choreutidae) with Afrotropical and Australasian distribution https://zookeys.pensoft.net/article/3577/ ZooKeys 355: 29-47

DOI: 10.3897/zookeys.355.6158

Authors: Jadranka Rota, Scott Miller

Abstract: Niveas Rota, new genus, and its two new species, N. agassizi Rota, new species, and N. kone Rota, new species, are described and illustrated. Niveas is assigned to the subfamily Choreutinae based on morphological and molecular data. Niveas agassizi is currently known only from Kenya and only from female specimens. Niveas kone has been found on the Solomon Islands and in Papua New Guinea (PNG). In PNG, larvae of this species have been reared from several species of Ficus (Moraceae). The two species are superficially quite dissimilar from each other. However, they share features in wing pattern and venation, as well as female genitalia, and the molecular data strongly support the monophyly of Niveas.

Pristomyrmex tsujii sp. n. and P. mandibularis Mann (Hymenoptera, Formicidae) from Fiji https://zookeys.pensoft.net/article/3306/ ZooKeys 340: 43-61

DOI: 10.3897/zookeys.340.5479

Authors: Eli Sarnat, Evan Economo

Abstract: Pristomyrmex tsujii sp. n., an endemic species of the Fiji islands, is described from the worker, ergatoid queen, alate queen and male castes. The alate queen and male castes of Pristomyrmex mandibularis Mann are also described for the first time. The ergatoid queens for both species appear to be morphologically intermediate between the worker and alate queen castes. Pristomyrmex tsujii is readily distinguished from P. mandibularis by the lack of well-developed propodeal spines. Although both species occur across the Fijian archipelago, they are rarely encountered and workers are most often collected from sifted litter. The descriptions are illustrated with specimen photographs, line drawings and a distribution map.

Three new species of Oreophryne (Anura, Microhylidae) from Papua New Guinea https://zookeys.pensoft.net/article/3122/ ZooKeys 333: 93-121

DOI: 10.3897/zookeys.333.5795

Authors: Fred Kraus

Abstract: I describe three new species of the diverse microhylid frog genus Oreophryne from Papua New Guinea. Two of these occur in two isolated mountain ranges along the northern coast of Papua New Guinea; the third is from Rossel Island in the very southeasternmost part of the country. All three are the first Oreophryne known from these areas to have a cartilaginous connection between the procoracoid and scapula, a feature usually seen in species far to the west or from the central cordillera of New Guinea. Each of the new species also differs from the many other Papuan Oreophryne in a variety of other morphological, color-pattern, and call features. Advertisement-call data for Oreophryne species from the north-coast region suggest that they represent only two of the several call types seen in regions further south, consistent with the relatively recent derivation of these northern regions as accreted island-arc systems. The distinctively different, whinnying, call type of the new species from Rossel Island occurs among other Oreophryne from southeastern Papua New Guinea but has been unreported elsewhere, raising the possibility that it may characterize a clade endemic to that region.

Abstract: Exocelina baliem sp. n. is described from the Baliem Valley in the Central Mountain Range of New Guinea (Papua Province, Indonesia).striolate elytra, different structure and setation of the male and female genitalia and tarsomeres, and inhabiting swampy ponds, the new species differs from all known New Guinea species, which have smooth elytra and are stream associated. It forms a monophyletic group with the Australian E. ferruginea (Sharp, 1882) and New Caledonian E. inexspectata Wewalka, Balke & Hendrich, 2010, based on shape of the paramere and structure of the male tarsi. Habitus, protarsomeres, and male and female genitalia are illustrated, comparing some structures with E. ferruginea and two New Guinea stream species. We briefly discuss the biogeographic relevance of this discovery.

Checklist of the ants (Hymenoptera, Formicidae) of the Solomon Islands and a new survey of Makira Island https://zookeys.pensoft.net/article/3605/ ZooKeys 257: 47-88

DOI: 10.3897/zookeys.257.4156

Authors: Eli Sarnat, Benjamin Blanchard, Benoit Guénard, John Fasi, Evan Economo

Abstract: The intent of this paper is to facilitate future research of the Solomon Islands ant fauna by providing the first comprehensively researched species inventory in over 75 years. The species list presented here includes the names of all ant species recorded from the islands that are available in the literature together with specimen records from several museum collections and new records from our 2008 Makira field expedition. All the names of described species presented are valid in accordance with the most recent Formicidae classification. In total, the checklist is composed of 237 species and subspecies (including 30 morphospecies) in 59 genera representing nine subfamilies. We report that the recent field expedition added 67 new species records to Makira and 28 new species records to the Solomon Islands. Our research recovered species occurrence records for 32 individual islands and five island groups. The five islands with the highest number of recorded species are: Makira (142 spp.), Guadalcanal (107 spp.), Malaita (70 spp.), Santa Isabel (68 spp.), and Rennell (66 spp.). Based on our results, we discuss the taxonomic composition of the archipelago’s ant fauna, which islands are most in need of additional sampling, and the importance of establishing biodiversity baselines before environmental threats such as the invasive ant Wasmannia auropunctata cause irrevocable harm to the native biodiversity.

Taxonomy of new relatives of Onthophagus catenatus Lansberge, 1883 from New Guinea (Coleoptera, Scarabaeidae, Scarabaeinae) https://zookeys.pensoft.net/article/3445/ ZooKeys 251: 49-67

DOI: 10.3897/zookeys.251.3994

Authors: Jan Krikken, Johannes Huijbregts

Abstract: Four new taxa from New Guinea are proposed in the dung beetle genus Onthophagus Latreille, 1802, all in the operational group of O. catenatus Lansberge, 1883. The group is discussed, defined, and the five taxa included are listed, keyed, and diagnosed. Three new species are described: Onthophagus abmisibilus (from West New Guinea, Indonesia), O. kokodanus, O. kokosquamatus (both from Papua New Guinea). One new species comprises a lowland and an upland subspecies: O. kokodanus kokodanus and kokodanus hagenaltus (both in Papua New Guinea).

Introduction of the Exocelina ekari-group with descriptions of 22 new species from New Guinea (Coleoptera, Dytiscidae, Copelatinae) https://zookeys.pensoft.net/article/3440/ ZooKeys 250: 1-76

DOI: 10.3897/zookeys.250.3715

Authors: Helena Shaverdo, Suriani Surbakti, Lars Hendrich, Michael Balke

Abstract: The Exocelina ekari-group is here introduced and defined mainly on the basis of a discontinuous outline of the median lobe of the aedeagus. The group is known only from New Guinea (Indonesia and Papua New Guinea). It contained four species to date: E. astrophallus (Balke, 1998), E. atowaso (Shaverdo, Sagata & Balke, 2005), E. munaso (Shaverdo, Sagata & Balke, 2005), and E. polita (Sharp, 1882). Twenty two new species are described herein: E. alexanderi sp. n., E. anggiensis sp. n., E. arfakensis sp. n., E. bifida sp. n., E. brahminensis sp. n., E. bundiensis sp. n., E. edeltraudae sp. n., E. ekari sp. n., E. eme sp. n., E. evelyncheesmanae sp. n., E. hansferyi sp. n., E. irianensis sp. n., E. kakapupu sp. n., E. knoepfchen sp. n., E. oceai sp. n., E. pseudosoppi sp. n., E. soppi sp. n., E. unipo sp. n., E. utowaensis sp. n., E. waigeoensis sp. n., E. weylandensis sp. n., and E. wondiwoiensis sp. n. The lectotype of Copelatus politus Sharp, 1882 is designated. A checklist and identification key to all species of the group are provided and important diagnostic characters (habitus, color, male antennae and protarsomeres 4–5, median lobes and parameres) are illustrated. Data on the distribution and habitat requirements are given. Representatives of the E. ekari-group are so far mostly known from lowland to lower montane habitats of the northern and central parts of New Guinea, the group is less diverse in higher altitudes.

High mitochondrial DNA sequence divergence in New Guinea Carabdytes stream beetles and the taxonomist’s dilemma when other evidence is kind of subtle… (and collecting localities are far far away) https://zookeys.pensoft.net/article/3416/ ZooKeys 247: 31-43

DOI: 10.3897/zookeys.247.3812

Authors: Andre Skale, Rene Tänzler, Lars Hendrich, Michael Balke

Abstract: Carabdytes upin tindige ssp. n. is described from the Arfak Mountains, Bird’s Head, Indonesian Papua. It is morphologically very similar to Carabdytes upin upin Balke et al., 1992, known from eastern Indonesian Papua eastward to the western limits of the Papuan Peninsula of Papua New Guinea. For 726 bp at the 3’ end of the mitochondrial cox1 gene, the subspecies differ by 8.1–9.2% uncorrected p-distance. However, we also document considerable cox1 divergence within Carabdytes upin upin. We find few diagnostic positions in the nuclear genes argenine kinase as well as elongation factor 1 alpha that suggest there are indeed two isolated groups of Carabdytes, but evidence in elongation factor 1 alpha is not unambiguous. We decided to highlight this phenomenon of ambiguous evidence for ongoing/just attained speciation by describing a subspecies. We argue that such cases are actually common once mitochondrial sequence data are routinely added to the taxonomist’s toolkit, and sometimes simply adding data from few nuclear genes will not suffice the solve taxonomic riddles. Here, detailed population genetic investigations would be required – for which sufficient numbers of specimens from a sufficiently wide geographical sampling might be nearly impossible to acquire.

Forever in the dark: the cave-dwelling azooxanthellate reef coral Leptoseris troglodyta sp. n. (Scleractinia, Agariciidae) https://zookeys.pensoft.net/article/3193/ ZooKeys 228: 21-37

DOI: 10.3897/zookeys.228.3798

Authors: Bert Hoeksema

Abstract: The coral species Leptoseris troglodyta sp. n. (Scleractinia, Agariciidae) is described as new to science. It is the first known azooxanthellate shallow-water agariciid and is recorded from the ceilings of caves at 5-35 m depth in West Pacific coral reefs. The corals have monocentric cup-shaped calices. They may become colonial through extramural budding from the basal coenosteum, which may cause adjacent calices to fuse. The size, shape and habitat of L. troglodyta are unique compared to other Leptoseris species, many of which have been recorded from mesophotic depths. The absence of zooxanthellae indicates that it may survive well in darkness, but endolithic algae in some corals indicate that they may be able to get some light. The presence of menianes on the septal sides, which may help to absorb light at greater depths in zooxanthellate corals, have no obvious adaptive relevance in the new species and could have been inherited from ancestral species that perhaps were zooxanthellate. The new species may be azooxanthellate as derived through the loss of zooxanthellae, which would be a reversal in Leptoseris phylogeny.

Revised concept of the genus Euryporus Erichson (Coleoptera, Staphylinidae, Staphylininae) and phylogenetic significance of Staphylinini from New Guinea https://zookeys.pensoft.net/article/2969/ ZooKeys 213: 51-62

DOI: 10.3897/zookeys.213.3210

Authors: Alexey Solodovnikov

Abstract: The Staphylinini rove beetle genus Euryporus Erichson from the subtribe Quediina is restricted to include only three species from the Western Palearctic region: E. picipes (Paykull, 1800), E. aeneiventris (Lucas, 1846), and E. princeps Wollaston, 1864. Euryporus argentatus Fauvel, 1881, E. warisensis Last, 1987 and E. multicavus Last, 1980, which do not even belong to the subtribe Quediina, are excluded from the genus. Of these, two were transferred to different genera: Tympanophorus argentatus (Fauvel, 1881), comb. nov., from Sumatra; and Hesperus warisensis (Last, 1987), comb. nov., from New Guinea. “Euryporus” multicavus could not be placed to any of the described genera of Staphylinini and is left as incertae sedis pending a broader study of the relevant fauna of this tribe in New Guinea and adjacent regions. The taxonomic history of Euryporus is reviewed, and an updated diagnosis of this genus is provided.

Rhyparida foaensis (Jolivet, Verma & Mille, 2007), comb. n. (Coleoptera, Chrysomelidae) and implications for the colonization of New Caledonia https://zookeys.pensoft.net/article/2311/ ZooKeys 157: 33-44

DOI: 10.3897/zookeys.157.1320

Authors: Jesus Gomez-Zurita

Abstract: The study of external morphology of the New Caledonian leaf beetle Dematochroma foaensis Jolivet, Verma & Mille (Chrysomelidae, Eumolpinae, Colaspoidini) substantiates its new combination into the genus Rhyparida Baly (Chrysomelidae, Eumolpinae, Nodinini). The species is redescribed here to highlight characters important for suprageneric diagnosis. This is the second species of Nodinini found in New Caledonia, otherwise rich in species of Colaspoidini, raising questions about the paucity of Rhyparida and this tribe in New Caledonian fauna, when they are dominant in surrounding archipelagoes, and very rich in potential source areas such as Australia and New Guinea. Some alternative explanations for this pattern are advanced, serving as alternative hypotheses until our knowledge on the ecology of these species improves or supported phylogenetic scenarios become available for this group.

At the lower size limit for tetrapods, two new species of the miniaturized frog genus Paedophryne (Anura, Microhylidae) https://zookeys.pensoft.net/article/2143/ ZooKeys 154: 71-88

DOI: 10.3897/zookeys.154.1963

Authors: Fred Kraus

Abstract: I describe two new species in the miniaturized microhylid frog genus Paedophryne from forests in southeastern Papua New Guinea. The first species is described on the basis of two specimens and exhibits female snout-vent length of 8.5–9.0 mm (no males known), whereas that of the second species, described on the basis of 12 specimens, is 8.8–9.3 mm, with males 8.1–8.9 mm. These frogs are smaller than the other two diminutive species described when the genus was recently erected, and they represent what are currently the smallest known species of tetrapods. The two species replace each other elevationally on the same mountain massif and occur in relative geographic proximity to the other named species of the genus. Females of both species contain only two enlarged ova, suggesting that they also possess clutch sizes at the extreme lower end of variation in frogs. All species of Paedophryne inhabit leaf litter, as seen for most other miniaturized anurans.

Revision of the termite family Rhinotermitidae (Isoptera) in New Guinea https://zookeys.pensoft.net/article/3005/ ZooKeys 148: 55-103

DOI: 10.3897/zookeys.148.1826

Authors: Thomas Bourguignon, Yves Roisin

Abstract: Recently, we completed a revision of the Termitidae from New Guinea and neighboring islands, recording a total of 45 species. Here, we revise a second family, the Rhinotermitidae, to progress towards a full picture of the termite diversity in New Guinea. Altogether, 6 genera and 15 species are recorded, among which two species, Coptotermes gambrinus and Parrhinotermes barbatus, are new to science. The genus Heterotermes is reported from New Guinea for the first time, with two species restricted to the southern part of the island. We also provide the first New Guinea records for six species of the genera Coptotermes and Schedorhinotermes. We briefly describe soldiers and imagoes of each species and provide a key based on soldier characters. Finally, we discuss the taxonomic and biogeographical implication of our results. A replacement name, Schedolimulus minutides Bourguignon, is proposed for the termitophilous staphylinid Schedolimulus minutus Bourguignon, to solve a question of secondary homonymy.

Abstract: Complete series of two species of the phragmotic drywood termite genus, Cryptotermes (Isoptera: Kalotermitidae), were found on Espiritu Santo, Vanuatu. Here, I describe for the first time the soldier of Cryptotermes albipes (Holmgren & Holmgren), which resembles C. domesticus but presents deep depressions on the head sides and vertex. The other species, here described as Cryptotermes penaoru sp. n., comes close to C. tropicalis, a species known from the tropical rainforest of northern Queensland, from which its soldier is distinguished by its more elongated head capsule.

The spider family Selenopidae (Arachnida, Araneae) in Australia and Asia https://zookeys.pensoft.net/article/2353/ ZooKeys 99: 1-103

DOI: 10.3897/zookeys.99.723

Authors: Sarah Crews, Mark Harvey

Abstract: The spider family Selenopidae Simon occurs worldwide in tropical and subtropical regions, currently containing nearly 200 species in five genera. We relimit and revise the family to include four new genera and 27 new species from Australia and Asia. The family Selenopidae is redefined, as are the genera Anyphops Benoit, Garcorops Corronca, Hovops Benoit, Selenops Latreille, and Siamspinops Dankittipakul and Corronca, to accommodate the new genera and to correct previous errors in the definition. The species of Selenops that occur throughout India and China are also reviewed. Three species occur in China: S. bursarius Karsch, also known from Japan, Korea and Taiwan, S. ollarius Zhu, Sha, and Chen, and S. radiatus Latreille, the type of the genus and most widespread selenopid. Selenops cordatus Zhu, Sha, and Chen is recognized as a junior synonym of S. radiatus, syn. n. Amamanganops gen. n. is monotypic, with A. baginawa sp. n., and is known only from the Philippine island of Mindoro. Godumops gen. n. is monotypic, with G. careus sp. n., and is known only from Papua New Guinea. Karaops gen. n. occurs throughout Australia and has 24 species: K. australiensis (L. Koch) comb. n., K. gangarie sp. n., K. monteithi sp. n., K. alanlongbottomi sp. n., K. keithlongbottomi sp. n., K. larryoo sp. n., K. jarrit sp. n., K. marrayagong sp. n., K. raveni sp. n., K. badgeradda sp. n., K. burbidgei sp. n., K. karrawarla sp. n., K. julianneae sp. n., K. martamarta sp. n., K. manaayn sp. n., K. vadlaadambara sp. n., K. pilkingtoni sp. n., K. deserticola sp. n., K. ngarutjaranya sp. n., K. francesae sp. n., K. toolbrunup sp. n., the type species K. ellenae sp. n., K. jenniferae sp. n., and K. dawara sp. n. The genus Makdiops gen. n. contains five species from India and Nepal: M. agumbensis (Tikader), comb. n., the type of the genus M. mahishasura sp. n., M. montigenus (Simon), comb. n., M. nilgirensis (Reimoser) comb. n., and M. shiva sp. n. The genus Pakawops gen. n. is monotypic and contains P. formosanus (Kayashima) comb. n. known only from Taiwan. Finally, Selenops aculeatus Simon is transferred to the genus Siamspinops, forming the new combination S. aculeatus (Simon) comb. n. The distribution and diversity of the Australasian selenopid fauna is discussed. Keys are provided to all of the selenopid genera and to the species of Karaops and Makdiops.

Australian gall-inducing scale insects on Eucalyptus: revision of Opisthoscelis Schrader (Coccoidea, Eriococcidae) and descriptions of a new genus and nine new species https://zookeys.pensoft.net/article/2338/ ZooKeys 58: 1-74

DOI: 10.3897/zookeys.58.507

Authors: Nate Hardy, Penny Gullan

Abstract: We revise the genus Opisthoscelis Schrader, and erect the genus Tanyscelis gen. n. with Opisthoscelis pisiformis Froggatt as its type species. Species of both genera induce sexually dimorphic galls on Eucalyptus (Myrtaceae) in Australia, with Opisthoscelis subrotunda Schrader also in Papua New Guinea. We synonymise the following taxa (junior synonym with senior synonym): Opisthoscelis fibularis Froggatt, syn. n. with Opisthoscelis spinosa Froggatt; Opisthoscelis recurva Froggatt, syn. n. with Opisthoscelis maculata Froggatt; Opisthoscelis globosa Froggatt, syn. n. (= Opisthoscelis ruebsaameni Lindinger) with Opisthoscelis convexa Froggatt; and Opisthoscelis mammularis Froggatt, syn. n. with Opisthoscelis verrucula Froggatt. We transfer seven Opisthoscelis species to Tanyscelis as Tanyscelis conica (Fuller), comb. n., Tanyscelis convexa (Froggatt), comb. n., Tanyscelis maculata (Froggatt), comb. n., Tanyscelis maskelli (Froggatt), comb. n., Tanyscelis pisiformis (Froggatt), comb. n., Tanyscelis spinosa (Froggatt), comb. n., and Tanyscelis verrucula (Froggatt), comb. n. We redescribe and illustrate the adult female of each named species of Opisthoscelis for which the type material is known, as well as the first-instar nymph of the type species of Opisthoscelis (Opisthoscelis subrotunda) and Tanyscelis (Opisthoscelis pisiformis). We describe four new species of Opisthoscelis: Opisthoscelis beardsleyi Hardy & Gullan, sp. n., Opisthoscelis thurgoona Hardy & Gullan, sp. n., Opisthoscelis tuberculata Hardy & Gullan, sp. n., and Opisthoscelis ungulifinis Hardy & Gullan, sp. n., and five new species of Tanyscelis: Tanyscelis grallator Hardy & Gullan, sp. n., Tanuscelis megagibba Hardy & Gullan, sp. n., Tanyscelis mollicornuta Hardy & Gullan, sp. n., Tanyscelis tripocula Hardy & Gullan, sp. n., and Tanyscelis villosigibba Hardy & Gullan, sp. n. We designate lectotypes for Opisthoscelis convexa, Opisthoscelis fibularis, Opisthoscelis globosa Froggatt, Opisthoscelis maculata, Opisthoscelis mammularis, Opisthoscelis maskelli, Opisthoscelis pisiformis, Opisthoscelis recurva, Opisthoscelis serrata, Opisthoscelis spinosa, and Opisthoscelis verrucula. As a result of our taxonomic revision, Opisthoscelis has six species and Tanyscelis has 12 species. We describe the galls of females for all 18 species and galls of males for 10 species of Opisthoscelis and Tanyscelis, and provide photographs of the galls for most species. A key to the adult females of the species of both genera is included.

New genus of diminutive microhylid frogs from Papua New Guinea https://zookeys.pensoft.net/article/2207/ ZooKeys 48: 39-59

DOI: 10.3897/zookeys.48.446

Authors: Fred Kraus

Abstract: A new genus of diminutive (10.1-11.3 mm) microhylid frogs is described from New Guinea that is unique in its combination ofonly seven presacral vertebrae, a reduced phalangeal formula that leaves the first fingers and first toes as vestigial nubs, and reduction of the prepollex and prehallux to single elements. Relationships to other genera are unknown, but overall similarity suggests some relationship to Cophixalus, although that genus also differs in some muscle characters and likely remains paraphyletic. The new genus contains two species, which are among the smallest known frogs in the world. Their miniaturization may be related to their inhabiting leaf litter, exploitation of which may for small size. The new genus is currently known only from one mountaintop in the southeasternmost portion of New Guinea and another on a nearby island. This region is part of the East Papuan Composite Terrane and, should this lineage prove endemic to that region, it may suggest that it originated prior to that geological unit’s docking with mainland New Guinea at 23–29 MY.

The spider family Micropholcommatidae (Arachnida: Araneae: Araneoidea): a relimitation and revision at the generic level https://zookeys.pensoft.net/article/2154/ ZooKeys 36: 1-321

DOI: 10.3897/zookeys.36.306

Authors: Michael Rix, Mark Harvey

Abstract: The araneoid spider family Micropholcommatidae Hickman, previously containing 34 southern-temperate species in eight genera, is relimited and revised at the generic level to include 18 genera from Australia, Lord Howe Island, New Caledonia, New Zealand, Papua New Guinea and Chile. Three subfamilies are proposed, and a new phylogenetic hypothesis for the family is presented as a result of two morphological cladistic analyses, used to test the phylogenetic position and phylogeny of the known micropholcommatid taxa. These cladistic analyses inferred a monophyletic Micropholcommatidae, belonging to the diverse araneoid symphytognathidan lineage, with the families Anapidae, Symphytognathidae and Micropholcommatidae further united by the newly proposed 'EbCY' clade. The genus Teutoniella Brignoli, previously included in the Micropholcommatidae, was found to be most closely related to an undescribed genus from South Africa, together forming a distinctive ‘teutoniellid’ lineage within the EbCY clade. The subfamily Micropholcommatinae Hickman, new rank contains the bulk of micropholcommatid diversity, with three tribes, 15 genera and 45 described species. The micropholcommatine tribe Micropholcommatini Hickman, new rank includes the nominate genus Micropholcomma Crosby & Bishop, along with three additional genera from Australasia and Chile: Micropholcomma has eight species, including the type, M. caeligenum Crosby & Bishop, and M. junee sp. n.; Pua Forster is monotypic, with P. novaezealandiae Forster; Tricellina Forster & Platnick is also monotypic, with T. gertschi (Forster & Platnick); and Austropholcomma gen. n. has two species, including the type A. florentine sp. n., and A. walpole sp. n. The micropholcommatine tribe Textricellini Hickman, new rank is a diverse and distinctive lineage, including all species previously described in the genus Textricella Hickman, which is hereby recognised as a junior generic synonym of Eterosonycha Butler syn. n.; the 20 previously described species of Textricella are thus transferred into Eterosonycha or other newly described genera. The Textricellini includes 10 genera from Australasia and Chile: Eterosonycha has four species, including the type E. alpina Butler (=Textricella parva Hickman syn. n.), E. complexa (Forster), E. aquilina sp. n. and E. ocellata sp. n.; Epigastrina gen. n. has three species, including the type E. fulva (Hickman), E. loongana sp. n. and E. typhlops sp. n.; Guiniella gen. n. is monotypic, with G. tropica (Forster); Raveniella gen. n. has three species, including the type R. luteola (Hickman), R. hickmani (Forster) and R. peckorum sp. n.; Rayforstia gen. n. has 12 species, including the type R. vulgaris (Forster), the two new species R. lordhowensis sp. n. and R. raveni sp. n., and the nine additional species R. antipoda (Forster), R. insula (Forster), R. mcfarlanei (Forster), R. plebeia (Forster), R. propinqua (Forster), R. salmoni (Forster), R. scuta (Forster), R. signata (Forster) and R. wisei (Forster); Normplatnicka gen. n. has three species, including the type N. lamingtonensis (Forster), N. chilensis sp. n. and N. barrettae sp. n.; Eperiella gen. n. has two species, including the type E. alsophila sp. n., and E. hastings sp. n.; Algidiella gen. n. is monotypic, with A. aucklandica (Forster); Taliniella gen. n. has two species, including the type T. nigra (Forster), and T. vinki sp. n.; and Tinytrella gen. n. is monotypic, with T. pusilla (Forster). The micropholcommatine tribe Patelliellini trib. n. includes only one monotypic genus, Patelliella gen. n., represented by the enigmatic species Patelliella adusta sp. n. from Lord Howe Island. The subfamily Taphiassinae subfam. n. includes two genera of distinctive, heavily punctate Micropholcommatidae from Australasia: Taphiassa Simon has six species, including the type T. impressa Simon, T. punctata (Forster), T. castanea sp. n., T. globosa sp. n., T. magna sp. n. and T. robertsi sp. n.; the genus Parapua Forster, erected by Forster (1959) for P. punctata, is hereby recognised as a junior generic synonym of Taphiassa (syn. n.). The endemic Tasmanian genus Olgania Hickman has five species, including the type O. excavata Hickman, O. cracroft sp. n., O. eberhardi sp. n., O. troglodytes sp. n. and O. weld sp. n. The subfamily Gigiellinae subfam. n. includes only one genus from south-eastern Australia and Chile, Gigiella gen. n., described for the two species G. milledgei sp. n. and G. platnicki sp. n. The distribution, diversity and Gondwanan biogeography of the Micropholcommatidae are discussed, and natural history information is provided where known; webs and egg sacs of Taphiassinae are described for the first time. Species level monographic coverage is provided for those faunas of conservation or biogeographic significance, including the largely undescribed Western Australian fauna, the Lord Howe Island fauna, the Tasmanian cave fauna and the southern Chilean fauna, with other species of conservation or biogeographic importance also described. In total, 26 new species, 12 new genera, one new tribe and two new subfamilies are described, taking the total documented micropholcommatid fauna to 58 species.

New microhylid Frogs from the Muller Range, Papua New Guinea https://zookeys.pensoft.net/article/2096/ ZooKeys 26: 53-76

DOI: 10.3897/zookeys.26.258

Authors: Fred Kraus, Allen Allison

Abstract: We describe from the Muller Range of New Guinea three new species of microhylid frogs, one each in the genera Albericus, Cophixalus, and Oreophryne. The new Albericus is unique in its combination ofan infrequent peeping call, oblique lores, wide snout and finger discs, and distinct tympanum. The new Cophixalus is distinguished by its combination of finger discs larger than toe discs, third toe longer than fifth, distinct tympanum, curved scapular ridges, dark postocular stripe, dark W-shaped mark above the shoulders, anda call consisting of a rapid series of 6–9 musical peeps. The Oreophryne is unique in its combination ofa cartilaginous connection of the procoracoid to the scapula, no webbing between the toes, fifth toe longer than third, short snout, dark face, and call consisting of an extended multi-note chuckle or cackle. Each species was either common or abundant. The new Cophixalus shows a predilection for caves, although it is not restricted to them. Many frogs occurring in the central highlands of New Guinea are wide-ranging across much of this high-elevational region, but others are of restricted distribution. The species described herein are likely members of the latter group, although it remains to be determined whether each will prove endemic to the Muller Range.

Masner, a new genus of Ceraphronidae (Hymenoptera, Ceraphronoidea) described using controlled vocabularies https://zookeys.pensoft.net/article/2043/ ZooKeys 20: 127-153

DOI: 10.3897/zookeys.20.119

Authors: Istvan Miko, Andrew Deans

Abstract: A ceraphronid wasp genus, Masner Mikó & Deans, gen. n., with one species, M. lubomirus Deans & Mikó, sp. n. is described from Australia and Fiji based on male specimens. This new genus challenges previous definitions of the two extant ceraphronoid families by sharing some character states with Megaspilidae (the presence of an expanded pterostigma and an occipital depression) and other character states with Ceraphronidae (the presence of uniramous anterior protibial spur, presence of a comb of the spur on the pro- and mesotibial spurs, a single mesotibial spur, an undivided synsternite, the presence of axillular setae, presence of Waterston’s evaporatorium and the fusion of the parossiculus with the gonostipes). Masner is distinguishable from all other Ceraphronoidea by the sensillar patch present on flagellomere 5 but absent from flagellomeres 6–9 and the presence of a dorsally visible depression surrounding anterior part of the petiole. The limits of Ceraphronidae and Megaspilidae are reviewed, and we provide new characters for family level diagnosis and classification. We also hypothesize that Masner is sister to the remaining Ceraphronidae.

New genera and species of the marine isopod family Serolidae (Crustacea, Sphaeromatidea) from the southwestern Pacific https://zookeys.pensoft.net/article/2029/ ZooKeys 18: 17-76

DOI: 10.3897/zookeys.18.96

Authors: Niel Bruce

Abstract: The marine isopod family Serolidae is reviewed for the oceanic regions of the tropical and subtropical southwestern Pacific, namely from off Lord Howe Island, Norfolk Island, northern Coral Sea, New Caledonia and Fiji. Two new genera are established: Sedorolis gen. n., monotypic, from New Caledonia and Myopiarolis gen. n., a widespread Southern Hemisphere genus with 11 (eight described) species. The following new species are described: Heteroserolis pellucida (New Caledonia), Sedorolis simplex (New Caledonia), Myopiarolis koro (Fiji), M. systir (New Caledonia), M. norfanz (Lord Howe Plateau and off Norfolk Island), M. lippa (northern Coral Sea), and Thysanoserolis orbicula (New Caledonia). Keys are provided to the serolid genera and the species of Myopiarolis from the southwestern Pacific. The genus Caecoserolis Wägele, 1994 is redefined and restricted to the type species.

Revision of Agathodesmus Silvestri, 1910 (Diplopoda, Polydesmida, Haplodesmidae) https://zookeys.pensoft.net/article/1996/ ZooKeys 12: 87-110

DOI: 10.3897/zookeys.12.206

Authors: Robert Mesibov

Abstract: Agathodesmus Silvestri, 1910 includes A. baccatus (Carl, 1926) comb. n. from New Caledonia, A. bucculentus (Jeekel, 1986) comb. n. from Queensland, Australia, and A. johnsi sp. n. and A. steeli Silvestri, 1910 (type species) from New South Wales, Australia. A. baccatus and A. bucculentus were formerly placed in Atopogonus Carl, 1926 syn. nov. The identity of the apparently congeneric Inodesmus jamaicensis Cook, 1896 sensu Loomis, 1969 from Jamaica is still uncertain, and Inodesmus Cook, 1896 remains a nomen inquirendum.

A description of four new species of fleas (Insecta, Siphonaptera) from Angola, Ethiopia, Papua New Guinea, and Peru https://zookeys.pensoft.net/article/1977/ ZooKeys 8: 39-61

DOI: 10.3897/zookeys.8.82

Authors: Michael Hastriter

Abstract: Four new species of fleas are described: Aphropsylla truncata sp. n. (Ethiopia), Ectinorus hirsutus sp. n. (Peru), Rhinolophopsylla traubi sp. n. (Angola), and Thaumapsylla wilsoni sp. n. (Papua New Guinea). Our understanding of the genus Aphropsylla is deficient, therefore a discussion of host/parasite relationships and new records from Uganda are provided. A key is provided for the genus Aphropsylla, while representatives of the other three genera are associated with existing keys to facilitate their identification. The presence of lucodiscs on Apropsylla and other genera is briefly discussed. The occurrence of lucodiscs among representatives of the order Siphonaptera deserves further investigation.
