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.     

Revision of the Neotropical Genus Hemibidessus Zimmermann (Coleoptera: Dytiscidae: Hydroporinae: Bidessini)

The genus Hemibidessus Zimmermann, 1921 is revised. Six species are recognized in the genus. Two new species are described, H. spirodiscus sp. n. from Bolivia and H. spangleri sp. n. from Argentina. A key for identifying the species is presented. The female genitalia are thoroughly illustrated and described for the first time for any species of Bidessini. Other important diagnostic structures are also illustrated including the male genitalia. A cladistic analysis is presented for 8 species (6 ingroup and 2 outgroup species) and 13 characters. A single most parsimonious cladogram was found.     

Jaw musculature of the Meiglyptini (Aves: Piciformes: Picidae)

The Meiglyptini comprise eight species of woodpeckers grouped into three genera, two of which contain three species ( Meiglyptes and Mulleripicus), while one genus includes two species ( Hemicircus). The purpose of this study is to describe the mandibular apparatus found in six species of Meiglyptini and to compare them with each other and with other woodpecker species. The results reveal a number of structures that are worth mentioning: (i) the components of the external mandibular adductor system of Hemicircus concretus, particularly the M. adductor mandibulae externus caudalis medialis, are underdeveloped compared with the other investigated species; (ii) the muscles of the internal mandibular system are structurally different among Meiglyptes species and are less developed, both in size and in structure, in H. concretus; (iii) the M . protractor quadrati is vestigial in Meiglyptes species; (iv) the muscles of the protractor system of the quadrate are relatively undeveloped in H. concretus; (v) most of the muscles of the pterygoideus system are structurally differentiated in Meiglyptes species. It appears that the complexity of the mandibular apparatus is associated with the type of food consumed, as the apparatus of the frugivorous species H. concretus is markedly different from that of the insectivorous species.     

Taxonomic study of the genus Dichrogaster Doumerc (Hymenoptera: Ichneumonidae: Cryptinae) in Japan

Japanese species of the genus Dichrogaster are revised. Four species are recognized. Two species, D. imperialis n. sp. and D. parva n. sp., are described. Dichrogaster liostylus (Thomson) and D. kichijoi (Uchida) are redescribed. A key to the Japanese species is provided.     

Revision of New Zealand Orthotylinae (Insecta: Hemiptera: Miridae)

Abstract

Six genera and 11 species of Orthotylinae are now known from New Zealand. Zanchius Distant is newly recorded. One new genus, Tridiplous, and seven new species of endemic New Zealand Orthotylini are described and illustrated. Four new species are described in Tridiplous: T. burrus, T. parvapiatus, T. penmani, and T. virens, and three new species are described in Zanchius: Z. ater, Z. rubicrux, and Z. totus. Keys are provided to identify New Zealand taxa of the tribes of Orthotylinae, genera and species of Halticini, genera of Orthotylini, and species of Tridiplous and Zanchius. The bugs are illustrated with colour habitus photos, and drawings including male and female genitalia. Economic importance is discussed.     

A Taxonomic Revision of Illiberis Walker (Lepidoptera: Zygaenidae: Procridinae) in Korea

The Korean species of Illiberis Walker are revised. A total of 10 species are recognized, including four species new to Korea: I. rotundata Jordan, I. psychina (OberthÜr), I. consimilis Leech, and I. hyalina (Staudinger). The identities of I. cybele Leech and I. assimilis Jordan, the two ambiguously defined Korean species, are reconfirmed with the examination of type specimens and additional materials. Photos of the adults and type materials are provided, and male and female genitalia of each species are illustrated. Biology and distribution for each species are briefly discussed with the larval host records from Korea.     

Praon Haliday (Hymenoptera: Braconidae: Aphidiinae) of Southeastern Europe: key, host range and phylogenetic relationships

A review of species in the genus Praon Haliday, 1833 is presented. Twenty described species are keyed and illustrated with scanning electron micrographs and line drawings. The Praon species presented in this work have been identified from 67 aphid taxa occurring on 120 plant taxa. Furthermore, 87 original parasitoid–aphid–plant associations of the species mentioned in the key are presented. Phylogenetic relationships among Praon species are reconstructed using parsimony and cladistic distance methods. Praon abjectum is the sister taxon to the remaining Praon species. We recognized three species group: “Parapraon”, “dorsale-yomenae” and “rosaecola”. Monophyly is suggested for “Parapraon” species group and paraphyly for “dorsale-yomenae” group. Finally, by phylogenetic reconstruction, a close phylogenetic relationship between “Parapraon” and “dorsale-yomenae” species group was found.     

Updated checklist of the mosquitoes (Diptera: Culicidae) of Croatia

Improvement of morphological and molecular identification methods allows the detection of new species of mosquitoes. The mosquito fauna of Croatia currently includes 52 species, belonging to eight genera, including Anopheles (12 species), Aedes (24 species), Coquillettidia (one species), Culex (seven species), Culiseta (six species), Orthopodomyia (one species), and Uranotaenia (one species). This is an updated checklist, which includes five new species found in Croatian mosquito fauna. Two of these are invasive mosquito species, Aedes albopictus (Skuse, 1895) and Aedes japonicus (Theobald 1901), which are spreading across Europe and Croatia. The other three species, Culex laticinctus (Edwards 1913), Culex torrentium (Martini 1925), and Anopheles daciae (Linton, Nicolescu & Harbach 2004) are autochthonous species which haven't been recorded so far. Since there are several more invasive species spreading across Europe, we assume that this is not the final list.     

Three New Species of Thraulodes (Ephemeroptera: Leptophlebiidae: Atalophlebiinae) from Venezuela

Three new species of Thraulodes from Venezuela are described. One species is known from male and female imagines, and the other two only from male imagines. With this, the known Thraulodes species for Venezuela are four. A key for the male imagines of the known species of Thraulodes from Venezuela is provided.     

Rotifera from Burundi: the Lepadellidae (Rotifera: Monogononta)

We studied the distribution of Lepadellidae (Rotifera) in freshwater habitats in the floodplain of the River Rusizi in northwest Burundi. Twenty-three species belonging to ColurellaBory de St. Vincent, 1824 (3 species), Lepadella Bory de St. Vincent, 1826 (18 species) and Squatinella Bory de St. Vincent, 1826 (2 species) are recorded, 22 of them are new to Burundi. One of the taxa encountered probably represents an unnamed species. Lepadella arabicaSegers & Dumont, 1993 is recognised as junior subjective synonym of Lepadella eurysterna Myers, 1942 (syn. nov.). Most of the taxa recorded are cosmopolitan or tropicopolitan, two are restricted to the tropical regions of the Old World and Australia, and one, Squatinella lunata Segers, 1993 is an Ethiopian endemic.     

Rhagodiinae: A new subtribe in the Chenopodiaceae

A new subtribe, Rhagodiinae, is described in the tribe Chenopodieae of the Chenopodiaceae. Three genera are included in this new subtribe: Rhagodia with 8 species, Einadia with 3 species, and Holmbergia with a single species. All the species are fully described and keys to the genera and species are given. Four new combinations are proposed: Rhagodia deltophylla, Einadia nutans, Einadia hastata and Einadia triandra.     

Revision of the genus Trogulus Latreille: the morphologically divergent Trogulus torosus species‐group of the Balkan Peninsula (Opiliones: Dyspnoi: Trogulidae)

Within the species‐rich European harvestman genus Trogulus Latreille, 1802, the Balkan Trogulus torosus species‐group as defined by Schönhofer and Martens is revised. The group is remarkable because it includes the world's largest Opiliones species, Trogulus torosus Simon, 1885, and Trogulus ozimeci sp. nov. is the first member of the family showing obvious adaption to subterranean life. According to nuclear 28S and mitochondrial cytochrome b gene data, the T. torosus species‐group and the Trogulus hirtus species‐group form a monophyletic unit. Only the former is treated here as a paraphyletic group. Despite this paraphyly, the T. torosus species‐group members share a number of morphological, morphometric, geographical, and ecological traits and are treated here as a unit for revisional work. Morphometric data are shown to be not only useful for species discrimination but also for species‐group delineation. Within the T. torosus species‐group six species are recognized: Trogulus banaticus Avram, 1971, Trogulus setosissimus Roewer, 1940, and T. torosus are re‐described; Trogulus megaligrava sp. nov. , T. ozimeci sp. nov. , and Trogulus tenuitarsus sp. nov. are described as new. Unusually within Trogulus, strong affiliations with subterranean habitats exist and are discussed. © 2013 The Linnean Society of London

Revision for the swordtail cricket genus Homoeoxipha (Grylloidea: Trigonidiidae: Trigonidiinae) from China

Species of Homoeoxipha are very small and always live on leaves of shrubs and grasses. This genus contains ten species worldwide and is distributed across five zoological regions, from Africa to New Guinea. Homoeoxipha lycoides is the type species of this genus and possesses the characteristic coloration for the genus. These coloration features resulted in some synonyms and disputes over species, because most Homoeoxipha species are ornamented with a similar coloration pattern. We compared and documented the differences between H. lycoides and its relatives in China. A new important character, the epiphallic transversal suture, is used to distinguish them. Based on this work, all of the Chinese species, H. lycoides, H. obliterata and H. nigripes, and one new species, H. eurylobus, with similar coloration to H. lycoides, are described and illustrated.
