Abstract

The genus Microedus LeConte, 1874 (Omaliinae: Anthophagini), previously known only from North America, is recorded for the Palaearctic fauna for the first time. Two palaearctic genera were synonymized with Microedus: Altaiodromicus Zerche, 1992 syn. n. and Liophilydrodes Nakane, 1983 syn. n. (replacement name for Lioplax Nakane & K. Sawada, 1956). The genus Microedus was redescribed, illustrated and its taxonomic relations with other genera of the Hygrogeus group are briefly discussed. Four species are (re-)described and illustrated: M. brevitarsis (Champion, 1925) comb. n. (from Geodromicus) (India: Uttarakhand), M. kastcheevi sp. n. (Altai and Dzhungar mts., eastern Kazakhstan), M. schilenkovi (Zerche, 1992) comb. n. (from Altaiodromicus) (Russia (Altai), Kazakhstan), and M. subtilis (Sharp, 1889) comb. n. (from Liophilydrodes) (Russia, Japan). An additional species from Kashmir remains unnamed due the absence of a male, and is compared with the Himalayan M. brevitarsis. A lectotype is designated for Anthophagus subtilis Sharp, 1889. Several new additional combinations are proposed (all these species were previously attributed to the genus Liophilydrodes): M. flavipennis (Watanabe, 1990) comb. n., M. pullus (Nakane & K. Sawada, 1956) comb. n., M. puncticollis (Nakane & K. Sawada, 1956) comb. n., M. suzukii (Watanabe, 1990) comb. n., and M. yamanakai (Watanabe, 1990) comb. n. The following new synonymies are established: M. subtilis = L. subtilis iturupensis Lafer, 2004 syn. n., = L. troglophilus Nakane & K. Sawada, 1956 syn. n. A key to Palaearctic species of Microedus is provided. Mouthparts and the aedeagus of the Nearctic M. austinianus LeConte, 1874 are illustrated for the first time. A distributional map of Microedus from Middle Asia is provided. Microedus schilenkovi is recorded from Kazakhstan for the first time. A checklist of the genus is presented. The genus Microdeus currently contains 16 species, seven in the Nearctic and nine in the Palaearctic Region.

Microedus LeConte, 1874 (Coleoptera: Staphylindae: Omaliinae: Anthophagini)，古北区的一个新属

Microedus LeConte, 1874 (Omaliinae: Anthophagini)属以前仅产于北美洲，这是首次在古北区动物群中记录到该属。两个古北属与 Microedus 同名：和 Liophilydrodes Nakane, 1983 syn.对 Microedus 属进行了重新描述，绘制了插图，并简要讨论了该属与 Hygrogeus 类其他属的分类关系。对四个物种进行了（重新）描述并绘制了插图：n. (from Geodromicus) (India: Uttarakhand), M. kastcheevi sp、n. (from Altaiodromicus) (Russia (Altai), Kazakhstan), and M. subtilis (Sharp, 1889) comb.由于没有雄虫，克什米尔的另一个种仍未命名，并与喜马拉雅山的 M. brevitarsis 进行了比较。An lectotype is designated for Anthophagus subtilis Sharp, 1889.提出了几个新的组合（所有这些种以前都归属于 Liophilydrodes 属）：n., M. puncticollis (Nakane & K. Sawada, 1956) comb：M. subtilis = L. subtilis iturupensis Lafer, 2004 syn.首次绘制了近地M. austinianus LeConte, 1874的口器和aeedagus。提供了中亚细亚Microedus的分布图。首次从哈萨克斯坦记录到了Microedus schilenkovi。报告还提供了该属的核对表。Microdeus属目前有16个种，其中7个种在近北极地区，9个种在古北地区。

期刊介绍： Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
