Taxonomic review of Mycetophagidae Leach (Coleoptera: Tenebrionoidea) in Korea with their host fungi

A taxonomic review of the fungivorous Korean Mycetophagidae is presented. Nine species in four genera belonging to two tribes are presented in Korea. Four species, Eulagius ussuriensis Nikitsky, Litargus japonicus Reitter, Mycetophagus irroratus (Reitter), and Mycetophagus pustulosus (Reitter), are newly recorded in Korea. Most species are associated with the fruiting bodies of higher fungi, fungus‐grown bark, and mold contaminated materials. In addition, we provide information on host‐fungi records of Korean mycetophagid species.     

A Taxonomic Note on the Little Known Family Prostomidae in Korea (Coleoptera: Tenebrionoidea)

A taxonomic study of the Korean Prostomidae is presented. Two species (Prostomis latoris Reitter, P. mordax Reitter) are recognized and P. mordax is reported for the first time in Korea. Comparison with type specimens was made. An illustration of the habitus and line drawings of diagnostic characters are provided.     

First record of the beetle family Biphyllidae (Coleoptera) in Korea

The Biphyllidae including four species, Biphyllus lewisi (Reitter), B. marmoratus (Reitter), B. rufopictus (Wollaston) and B. throscoides (Wollaston), are discovered for the first time in Korea. A key, habitus photographs and illustrations of diagnostic characters of the species are presented.     

New species of the weevil subgenus Eunihus Rtt., genus Otiorhynchus germ. (Coleoptera, Curculionidae), from the Caucasus and Turkey

Otiorhynchus khatiparicus Davidian et Arzanov, sp. n. and O. meoticus Davidian et Arzanov, sp. n. are described in the subgenus Eunihus Reitter, which was not known from the Caucasus before. Both of the new species are very similar to O. rhilensis Stierlin from Bulgaria and O. uludagicus Magnano from NW Turkey.     

Révision de la tribu des Lachnogyini Reitter, 1904 sensu nov. et description d’un nouveau genre et d’une espèce nouvelle du désert de Taklamakan,Chine (Coleoptera : Tenebrionidae,Pimeliinae)

La tribu des Lachnogyini Reitter, 1904 sensu nov. est révisée. Les caractères distinctifs et la position systématique des genres Lachnogya Ménétriés, 1849, Netuschilia Reitter, 1904, Klewaria Reitter, 1916 et Lachnodactylus Seidlitz, 1898 sont discutés. La rotation de l’édéage dans l’abdomen, face ventrale visible de dessus, permet de l’inclure dans la sous-famille des Pimeliinae. Un genre nouveau de Lachnogyini, sous-famille des Pimeliinae (sensu Doyen & Tschinkel 1982), est créé pour recevoir une nouvelle espèce du désert froid de Taklamakan (Xing Kiang, Chine) : Taklamakania lepetzi, n. gen., n. sp. Une nouvelle espèce d’Afghanistan : Lachnogya skopini n. sp., est décrite. En revanche, le genre Lachnodactylus est transféré à la tribu des Trachyscelini en raison de la position ventrale de son édéage.     

First Record of the Family Passandridae in Korea (Coleoptera: Cucujoidea)

A taxonomic study of the Korean Passandridae is presented. The family, genus and species (Ancistria apicalis Reitter) are reported for the first time in Korea. Comparison with a lectotype was made. An illustration of the habitus and line drawings of diagnostic characters are provided.     

First phylogenetic analysis of the subfamily Pachydeminae (Coleoptera,Scarabaeoidea, Melolonthidae): the Palearctic Pachydeminae*

This paper presents the first phylogenetic analysis of Pachydeminae Reitter, 1902 ; one of the least known subfamilies of Melolonthidae, `leaf‐chafers' (Scarabaeoidea, Coleoptera). Some species of Pachydeminae have recently become agricultural pests in southern Spain. We analysed the phylogenetic relationships among 49 species belonging to 16 genera in the Palearctic region, based on a set of 63 morphological characters from the adult external morphology, wing anatomy, mouthparts and male and female genitalia. The last three sets of characters are described here for the first time. The phylogeny shows that the Palearctic Pachydeminae are monophyletic within the subfamily. Mouthparts and male and female genitalia provide the best synapomorphies for intergeneric relationships. In contrast, most of the external morphological characters used in the taxonomy of Pachydeminae are highly homoplastic. The phylogeny shows a basal split between the genera Hemictenius Reitter, 1897; Pachydema Castelnau, 1832, and the monospecific Peritryssus Reitter, 1918; and a second clade including the rest of genera. The remarkable Peritryssus is confirmed as a Pachydeminae, being the sister group to the monophyletic Hemictenius . Except for the position of P. rubripennis (Lucas, 1848) and P. zhora Normand, 1951, the phylogeny supports the monophyly of Pachydema but rejects the traditional division into species groups and the monophyly of the endemic Canarian species. In contrast, Tanyproctus Faldermann, 1835, must be rejected as polyphyletic. Otoclinius Brenske, 1896, is also probably polyphyletic (two new species synonymies), whereas Leptochristina Baraud and Branco, 1991 , is either mono‐ or paraphyletic. The two Mediterranean genera Ceramida Baraud, 1897, and Elaphocera Gené, 1836, form a monophyletic group, this clade being the best supported by the data set. Ceramida is clearly monophyletic, whereas Elaphocera is probably monophyletic except for E. barbara Rambur, 1843, which shares with Ceramida the character state for numerous mouthpart and genitalic characters. The phylogeny questions the generic status of the small and monospecific genera of Pachydeminae. The monotypic Alaia Petrovitz, 1980 , and Brenskiella Berg, 1898, are merged with Europtron Marseul, 1867, into one clade, whereas Atanyproctus Petrovitz, 1954, is grouped with some species of Tanyproctus , and the monotypic Pachydemocera Reitter, 1902 , is proposed as a junior synonym of Elaphocera .     

Phylogenetics,historical biogeography and molecular species delimitation of Gnaptorina Reitter (Coleoptera: Tenebrionidae: Blaptini)

With 38 described species or subspecies, Gnaptorina Reitter is the second‐most species‐rich genus in the darkling beetle subtribe Gnaptorinina (Tenebrionidae: Tenebrioninae). In this study, we reconstructed a phylogeny of the genus based on one nuclear and three mitochondrial genes and used this phylogeny to explore the historical biography and diversification of Gnaptorina species. We implemented multiple molecular species delimitation approaches to reassess the status of Gnaptorina species and taxonomic subdivisions of the genus. Dating and historical biogeography analyses suggest an early Eocene origin of the genus, with the southeastern regions of the Tibetan Plateau most likely as areas of origin. Based on these results, we propose a new classification for Gnaptorina with three major clades identified. Consequently, the monotypic subgenus Boreoptorina is newly synonymized with the more species‐rich subgenus Hesperoptorina, and G. dongdashanensis Shi is transferred from Hesperoptorina to the subgenus Gnaptorina. In addition, G. minxiana Medvedev, formerly treated as a subspecies of G. potanini Reitter, is elevated to species. Results of molecular species delimitation analyses are largely congruent and confirm the status of most morphological species.

Gondwanan Gymnochilini (Coleoptera: Trogossitidae): generic concepts,review of New Zealand species and long‐range Pacific dispersal

Members of Leperina Erichson (Trogossitidae: Gymnochilini) from New Zealand, New Caledonia and Lord Howe Island are morphologically similar to members of the endemic Juan Fernandez Island genus Phanodesta Reitter, sharing at least one obvious character, elytral carinae that are beaded and contain well‐defined punctures. To test the monophyly of Leperina and Phanodesta, we reconstructed phylogenetic relationships of the genera of the tribe Gymnochilini by a cladistic analysis of 22 terminals and 47 adult characters rooted with one genus of trogossitine. Leperina is rendered paraphyletic by the placements of Seidlitzella Jakobson and Phanodesta. Kolibacia n.gen. (type species Leperina tibialis Reitter) is described for east Palaearctic species included formerly in Leperina (two new combinations); New Zealand Leperina and other species from New Caledonia and Lord Howe Island (Ostoma pudicum Olliff) are transferred to Phanodesta (six new combinations); and the remaining species are retained in Leperina. The following species are described as new: Phanodesta carinata n.sp., P. manawatawhi n.sp., P. oculata n.sp. and P. tepaki n.sp. Leperina ambiguum Broun is transferred to Grynoma Sharp resulting in a new combination and three new synonymies for New Zealand trogossitines: Leperina interrupta Brookes n.syn. and Leperina sobrina (White) n.syn. [= Phanodesta farinosa (Sharp)], and Trogosita affinis White n.syn. (= Tenebroides mauritanicus Linnaeus). A key to the New Zealand species and a checklist for the species of the Kolibacia, Leperina and Phanodesta are provided. The derived placement of Juan Fernandez Phanodesta in the phylogeny is evidence for long‐distance dispersal from Australasia. A tally of all Juan Fernandez Islands Coleoptera shows derivation mostly from Chile and South America, with few from the southern Pacific region, rarely from Australasia.     

A taxonomic revision of Limnobaris Bedel in the strict sense (Coleoptera,Curculionidae, Baridinae), with particular emphasis on the species found in China

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