The taxonomy and diversity of Platerodrilus (Coleoptera,Lycidae) inferred from molecular data and morphology of adults and larvae

The Oriental neotenic net-winged beetles attracted attention of biologists due to conspicuous large-bodied females; nevertheless phylogenetic relationships remain contentious and only a few species are known in both the fully metamorphosed males and neotenic females. The phylogenetic analyses and morphology of larvae and adults provide data for investigation of relationships and species delineation. Platrilus Kazantsev, 2009, Platerodriloplesius Wittmer, 1944, and Falsocalochromus Pic, 1942 are synonymized to Platerodrilus Pic, 1921. Platrilus hirtus (Wittmer, 1938) and Pl. crassicornis (Pic, 1923) are transferred to Platerodrilus Pic, 1921. Platerodrilus hoiseni Wong, 1996 is proposed as a junior subjective synonym of Falsocalochromus ruficollis Pic, 1942. Platerodrilus is divided in three species-groups: P. paradoxus, P. major, and P. sinuatus groups defined based on the shape of genitalia and molecular phylogeny. The following species are described: Platerodrilus foliaceussp. n., P. wongisp. n. (P. paradoxus group); P. ngisp. n., P. wittmeri (P. major group), P. ijenensissp. n., P. luteussp. n., P. maninjauensissp. n., P. montanussp. n., P. palawanensissp. n., P. ranauensissp. n., P. sibayakensissp. n., P. sinabungensissp. n., P. talamauensissp. n., and P. tujuhensissp. n. (P. sinuatus group). P. korinchiana robinsoni Blair, 1928 is elevated to the species rank as P. robinsoni Blair, 1928, stat. n. The conspecific semaphoronts are identified using molecular phylogeny for P. foliaceussp. n., P. tujuhensissp. n., P. montanussp. n., P. maninjauensissp. n.; additional female larvae are assigned to the species-groups. Diagnostic characters are illustrated and keys are provided for P. paradoxus and P. major groups.     

Multiple ancient origins of neoteny in Lycidae(Coleoptera): consequences for ecology and macroevolution

Neoteny, the maintenance of larval features in sexually mature adults, is a radical way of generating evolutionary novelty through shifts in relative timing of developmental programmes. While controlled by the environment in facultative neotenics, retention of larval features is obligatory in many species of Lycidae (net-winged beetles). They are studied here as an example of how developmental shifts and ecology interact to produce macroevolutionary impacts. We conducted a phylogenetic analysis of Lycidae based on DNA sequences from nuclear (18S and 28S rRNA) and mitochondrial (rrnL, cox1, cob and nad5) genes from a representative set of lineages (73 species), including 17 neotenic taxa. Major changes of basal relationships compared with those implied in the current classification generally supported three independent origins of neotenics in Lycidae. The southeast Asian Lyropaeinae and Ateliinae were in basal positions indicating evolutionary antiquity, also confirmed by molecular clock estimates, unlike the neotropical leptolycines nested within Calopterini and presumably much younger. neotenics exhibit typical K-selected traits including slow development, large body size, high investment in offspring and low dispersal. This correlated with low species richness and restricted ranges of neotenic lineages compared with their sisters. Yet, these factors did not impede the evolutionary persistence of affected lineages, even without reversals to fully metamorphosed forms, contradicting earlier suggestions of recent evolution from dispersive non-neotenics.

Description of Hydrobius orientalis sp. n., the first species of the subtribe Hydrobiusina from the Oriental Region (Coleoptera: Hydrophilidae: Hydrophilini)

The first Oriental species of the water scavenger beetle subtribe Hydrobiusina, Hydrobius orientalis sp. n., is described and illustrated from Guandong Province, China. It is unique in the subtribe by lacking elytral serial punctures. The species appears most closely related to Hydrobius melaenus (Germar, 1824) of eastern North America.     

Taxonomic revision of the subfamily Toradjiinae (Crustacea: Oniscidea: Scleropactidae)

In the present revision four genera and 32 species are recognized. One genus, Paratoradjia , and 17 species, namely Adinda malaccensis, A. sumatrana, A. palniensis, A. carli, A. nilgiriensis, A. lobata, A. triangulifera, A. rudeli, A. lamellata, Protoradjia paeninsulae, P. insularis, P. montana, P. pilosa, Paratoradjia beroni, P. vietnamensis, P. sulcata and Toradjia hirsute , are described as new. The neotype of Toradjia cephalka and lectotypes of Adinda weberi, Protoradjia jacobsoni, Toradjia gorgona and T. celebensis are established. Adinda cahgarii is considered to be a junior synonym of Adinda weberi , and A. conglobator , a species inquirenda. Toradjia dollfusi is transferred to the genus Adinda , and T. indosinensis to Paratoradjia. The characters of the group and its taxonomic position within the Oniscidea are discussed: it is transferred from the Eubelidae to the Scleropactidae, of which it constitutes a separate subfamily, the Toradjiinae. A map and comments on the distribution of genera and species are included.     

A revision of the Cautires obsoletus species group from Java (Coleoptera,Lycidae)

The Javanese fauna of the species group Cautires obsoletus is revised. Altogether, eight Javanese species were classified in the group; five of them are proposed to be junior subjective synonyms: Cautires fruhstorferi Dudkova & Bocak, 2010, a replacement name of Bulenides lineatus Pic, 1921, Cautires javanicus Bourgeois, 1883, Cautires inhumeralis (Pic, 1921), Cautires nigromaculatus (Pic, 1925), and Cautires pudicus (Kleine, 1931) (all synonymized to Cautires obsoletus Waterhouse, 1879). Three Javanese species are redescribed: Cautires apicalis (Pic, 1925), Cautires obsoletus (Waterhouse, 1878), and Cautires singularithorax (Pic, 1925). Cautires apicalis (Pic, 1925) is removed from the synonymy of Cautires corporaali (Pic, 1921) and reinstated as a valid name. Three new species are proposed: Cautires walteri sp. n., Cautires taoi sp. n., and Cautires sukosarensis sp. n. All species are keyed and principal diagnostic characters are illustrated. The distribution and relationships to Cautires fauna of other Great Sundas islands are briefly discussed.     

A revision of the genus Paronthobium from New Caledonia (Coleoptera: Scarabaeidae: Scarabaeinae: Epilissini)

A revision of the New Caledonian genus Paronthobium Paulian 1984 is presented. Anonthobium Paulian 1984 is synonymized with Paronthobium Paulian 1984 after evaluating the diagnostic characters originally introduced by Paulian to separate them. Upon examination of the type specimens, Onthobium caledonicum Paulian 1935 is separated from O. simplex Fauvel 1903 and restored as valid. Anonthobium moui Paulian 1984 is synonymized with Anonthobium micros Paulian 1984. Fifteen new species are described: P. adio n. sp., P. daghfousi n. sp., P. dierkensi n. sp., P. farino n. sp., P. iac n. sp., P. julieni n. sp., P. memaoya n. sp., P. minutum n. sp., P. nasutum n. sp., P. orientale n. sp., P. peckorum n. sp., P. petchecara n. sp., P. subdentatum n. sp., P. taom n. sp. and P. tchingou n. sp. The genus Paronthobium is now composed of 22 species. Illustrations of parameres and of male protibiae are provided for each species. Distribution maps and a key to species are given.     

Taxonomic review of Agraphydrus from Japan (Coleoptera: Hydrophilidae: Acidocerinae)

The Japanese species of the genus Agraphydrus are revised. Five species are recognized, including Agraphydrus ogatai sp. nov. from Honshu, Shikoku and Kyushu. The new species can be distinguished by the coarse ground punctures on the pronotum and elytra, and by the shape of parameres. All species except A. luteilateralis are redescribed. All species are diagnosed, relevant morphological characters are illustrated, distributional records are summarized and an updated key is provided.     

Molecular phylogeny of the tribe Erotini with description of a new genus from China (Coleoptera: Lycidae)

Erotini is a small tribe of net‐winged beetles known from the northern temperate zone. We investigated relationships and limits of tribes and genera using a molecular phylogeny inferred from rrnL, cox1 and nad5 mtDNA fragments. Lopheros Leconte, 1881 and Pseudaplatopterus Kleine, 1940 were inferred in current molecular analyses as terminal lineages within Erotini. Therefore, we consider Lopherotini Kazantsev, 2012 and Pseudaplatopterina Kazantsev, 2012 as junior synonyms of Erotini Leconte, 1881. The Platycis genus group comprises 19 species representing several genus‐group taxa previously placed in Platycis s. l. Konoplatycis Nakane, 1969 was recovered as a deeply rooted lineage of Erotini and we inferred another independent lineage for which we propose a new genus Sinoplatycis gen. nov. Additionally, we studied the diversity of Platycis s. l. in Asia, found their highest diversity in the temperate forest habitats of Eastern Asia and inferred the paraphyletic character of the subgenus Erotides s. str. Five new species are described from China: Sinoplatycis cardinalis sp. nov. , S. zhani sp. nov. (type species of Sinoplatycis gen. nov. ), Erotides brunnescens sp. nov. , E. pusillus sp. nov. and E. slipinskii sp. nov. The molecular phylogeny shows deep splits of Japanese species with respect to the continental Eurasian fauna and the role of shallow seas and mountain systems in the diversification of the Platycis genus group.     

Revision of the Chinese species of the genus Coenochilus Schaum (Coleoptera,Scarabaeidae, Cetoniinae)

Summary

The Chinese species of the genus Coenochilus Schaum, 1841 are revised, including a new species, C. pilosus n. sp. described from southern China (also from Vietnam and Laos). The lectotype for Coenochilus uncinatipes Moser, 1915 is designated, and this name is recognized as a junior synonym of C. bifoveolatus Fairmaire, 1888. Previously published synonymy of Coenochilus apicalis Westwood, 1873 and C. armiger Westwood, 1873 is confirmed based on the examination of type specimens. The neotype of C. tonkinensis Moser, 1910 is designated, and C. clinteroceroides Jákl, 2015 is synonymized with this species. Coenochilus tonkinensis is newly recorded from China, while Chinese records of C. nitidus Arrow, 1910 are verified as misidentification of C. striatus Westwood, 1873, thus C. nitidus is removed from the Chinese fauna. Diagnoses and illustrations are provided for all five Chinese species. A key to Chinese species and new distribution records are also presented.??     

Taxonomic revision of genus Ablattaria Reitter (Coleoptera,Silphidae) using geometric morphometrics

The genus Ablattaria Reitter, 1884 (Coleoptera: Silphidae: Silphinae) is revised. Four taxa are recognized as valid species: Ablattariaarenaria (Kraatz, 1876), Ablattariacribrata (Ménétries, 1832), Ablattarialaevigata (Fabricius, 1775) and Ablattariasubtriangula Reitter, 1905. Ablattarialaevigatavar.meridionalis Ganglbauer, 1899 is newly treated as a junior subjective synonym of Ablattarialaevigata. Lectotypes are designated for Phosphugaarenaria Kraatz, 1876, Ablattariaarenariavar.punctigera Reitter, 1884, Ablattariaarenariavar.alleoni Portevin, 1926, Silphacribrata Ménétries, 1832, Silphalaevigata Fabricius, 1775, Silphagibba Brullé, 1832, Ablattariagibbavar.costulata Portevin, 1926, Ablattariagibbavar.distinguenda Portevin, 1926, Ablattariagibbavar.punctata Portevin, 1926 and Ablattariasubtriangula Reitter, 1905. The distribution of all taxa is mapped, based on material examined. Geometric morphometric methods were used to evaluate shape variability in Ablattaria. Results indicated sexual dimorphism in all species. Shape inconsistency was found between the sexes of all taxa when tested independently. The first two relative warp axes indicated 65.17% shape variation in males and 65.72% in females. Canonical variate analysis separated the taxa studied. There was minimal overlap between some groups in both sexes. Differences in body shape between populations of Ablattarialaevigata from Central Europe, Italy and Greece + Turkey were also examined. Relative warps implied 58.01% shape variability on both axes in males and 64.78% in females. CVA revealed noticeable overlaps between the groups, although the Italian population demonstrated a higher separation in both sexes.     

A revision of Japanese species of the genus Psammoecus Latreille (Coleoptera,Silvanidae)

Japanese species of the genus Psammoecus Latreille, 1829 are taxonomically revised. Four new species, P. scitus sp. n. (misidentified with P. quadrimaculatus), P. labyrinthicus sp. n., P. boreas sp. n. and P. omotoensis sp. n. are described. Psammoecus bipunctatus (Fabricius, 1792), P. trimaculatus Motschulsky, 1858 (misidentified with P. triguttatus), P. simoni Grouvelle, 1892, P. fasciatus Reitter, 1874 and P. triguttatus are redescribed. Another described species whose distribution in Japan is questionable. P. quadrimaculatus is also redescribed. Lectotype and paralectotype of P. fasciatus and P. triguttatus are designated.     

First records of Microptila Ris (Trichoptera: Hydroptilidae) from Japan, with description of a new species

Microptila orienthula , sp. n. from Japan is described and illustrated based on adults of both sexes. The new species represents the first finding of Microptila in the Eastern Palaearctic Region, and it appears to be more closely related to Oriental species of Microptila than to the two Western Palaearctic species. The finding of a new species with affinities to the Oriental species as far northeast as Japan is noteworthy but fits well with general zoogeographical affinities of the Japanese fauna to the Oriental Region. The type locality indicates a hygropetric habitat for the larva, in agreement with the known larval habitat of the European type species Microptila minutissima Ris, 1897.     

A revision of the South African Chaetocnema gahani speciesgroup,with descriptions of four new flea beetle species (Coleoptera: Chrysomelidae)

The Chaetocnema gahani species-group from Southern Africa is herein analyzed and revised. It includes C. gahani Jacoby 1897, C. brincki (Bechyné 1959), C. capeneri n. sp., C. danielssoni n. sp., C. sudafricana n. sp., and C. tuckeri n. sp. A key to all the species is presented. Line drawings of male and female genitalia and scanning electron micrographs of six diagnostic morphological characters are also included, along with ecological and zoogeographical data. Finally, discriminant analyses using the six morphological characters supports the close affinity of the six species within the C. gahani group.     

A revision of the genus Trixa Meigen （Diptera： Tachinidae）

The genus Trixa Meigen, 1824 is revised. Dexiotrix Villeneuve, 1936 and Trixella Mesnil, 1980, each of which was sometimes treated as a distinct genus, are treated as junior synonyms of Trixa Meigen. Two species from Sichuan and Yunnan, China, are described as new to science, viz. Trixa chinensis sp. nov. and T. chaoi sp. nov. T. alpina Meigen is treated as a junior synonym of T. caerulescens Meigen. T. nox (Shima) and T.pubiseta (Mesnil) are newly recorded from China. Males of T. pubiseta (Mesnil) and T.longipensis (Villeneuve) are described for the first time. Diagnoses, figures and a key to twelve species in Trixa are given.
