Review of the Eospilarctia yuennanica group (Lepidoptera, Erebidae, Arctiinae) from the Indo - Himalayan region, with description of two new species and one subspecies

Twonew Eospilarctia species and one new subspecies from China, Myanmar and Vietnam, respectively, are described. Superficially the new species Eospilarctia maciaisp. n., Eospilarctia naumannisp. n. and Eospilarctia yuennanica fansipanassp. n. resemble related congeners but they can be distinguished by the differences in wing pattern, genitalia and distribution provided. Eospilarctia yuennanica guangdonga Dubatolov, Kishida & Wang, 2008 is upgraded to species level. A checklist of the genus Eospilarctia and a key to the Eospilarctia yuennanica (Daniel, 1943) species-group, based on external characters and male genitalia, is presented.     

Taxonomic and morphological survey of the Lygephila lusoria (Linnaeus, 1758) species-group with description of a new species (Lepidoptera,Erebidae, Toxocampinae)

The taxa of the Lygephila lusoria (Linnaeus, 1758) species-group are revised. The genital features of all known taxa are described and illustrated with special reference to the structure of vesica. The male genitalia of L. pallida pallida (Bang-Haas, 1907) are described and illustrated for the first time. L. pallida subpicata (Wiltshire, 1971) is treated here as a species, L. pallida subpicata (Wiltshire, 1971), stat. n., distinct from L. pallida. A new species, L. minima, sp. n.,from South Russia is described. Illustrations of the holotype and its genitalia are provided; a diagnostic comparison with L. pallida is given. L. alaica Remm, 1983 is included in the L. lusoria species-group for the first time.     

Revision of the Chaetocnema picipes species-group (Coleoptera,Chrysomelidae, Galerucinae,Alticini) in China,with descriptions of three new species

The lectotype of C. fortecostata is designated. A key to all known species of this group from China and the illustrations of habitus and genitalia are provided. A distribution map of species is given.     

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.??     

Description of nine new species of Heliura Butler from South America (Lepidoptera,Erebidae, Arctiinae,Arctiini, Ctenuchina)

They are illustrated in habitus and genitalia, and their phylogenetic affinities are discussed based on morphological evidence.     

Revision of the genus Xylomoia Staudinger (Lepidoptera: Noctuidae), with descriptions of two new species

Seven species are included in the genus Xylomoia Staudinger, two of which are new: X. retinax sp.n. from the Novosibirsk area, Western Siberia, and from the Chelyabinsk area, southern Ural Mountains, and X. stangelmaieri sp.n. from Caorle, Venezia Giulia, on the Adriatic coast. A North American species, Chortodes didonea (Smith) comb.n., is removed from the genus. According to a cladistic analysis, the genus Xylomoia comprises one plesiomorphic species group, the chagnoni group, and two apomorphic groups: the graminea and strix groups. The latter are exclusively temperate Palaearctic. Xylomoia chagnoni (Barnes & McDunnough) is the only Nearctic species of the genus, and the loosely related X. apameaoides (Hacker) was recently described from Turkey. In geographical isolation, these two species have retained many ancestral features. In the more central area, the common ancestor of the graminea and strix groups has evolved into at least five species. The locality and rarity of the species of Xylomoia seemingly result from adaptation of the species to moist habitats, the larvae probably bore inside grass stems (the case of X. chagnoni ). What are called lock-and-key mechanisms may lead to the use of non-independent character states in a cladistic analysis; particularly in the case of homoplasy this kind of double-weighting may result in erroneous cladograms. In Xylomoia , deleting female lock-and-keys affected only the number of cladograms produced, whereas omitting the corresponding male characters had profound effects on the cladogram.     

Taxonomic and faunistic studies of the Sepsidae (Diptera) from Vietnam,with descriptions of six new species

Revision of the fishes of the New Zealand genus Hemerocoetes (Perciformes: Percophididae), with descriptions of two new species

Abstract

Five species of the marine New Zealand genus Hemerocoetes are recognised and described: H. monopterygius (Schneider) [= H. acanthorhynchus (Forster)]; H. morelandi n.sp.; H. pauciradiatus Regan; H. artus n.sp.; and H. macrophthalmus Regan. H. waitei Regan is placed in synonymy with H. macrophthalmus. H. morelandi differs from the two other species possessing a relatively wide interorbital and small eye in lacking a dorsal iris flap and (mature males) in having an elongate first dorsal fin ray. It differs from H. monopterygius in having an elongate barbel at the tip of the upper jaw in mature males, and from most specimens of H. pauciradiatus in having 36–38 anal fin rays. H. morelandi is known primarily from off the Auckland Islands and Campbell Island, whereas H. monopterygius is widespread around the North and South Islands and the Chatham Islands, and H. pauciradiatus is commonest off the southern portion of the South Island and off the Chatham Islands. H. artus differs most noticeably from the similar H. macrophthalmus in having unbranched dorsal fin rays. Both have relatively narrower interorbitals and larger eyes and occur in deeper water than the other three species, but H. artus is known from south of latitude 44.0°S, whereas H. macrophthalmus is known primarily from north of about 44.5°S. In possessing a continuous dorsal fin lacking spines, Hemerocoetes is the most distinctive of the percophidid genera. It most closely resembles the western Australian Branchiopsaron ozawai and the Japanese Spinapsaron barbatus.
