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.
微埃德蛛属（Microedus LeConte，1874）（阎甲科：花阎甲族）此前仅在北美洲有记录，此次首次在古北区动物区系中被发现。两个古北区的属被归并为微埃德蛛属的同物异名：阿尔泰阎甲属（Altaiodromicus Zerche，1992）新异名，以及滑阎甲属（Liophilydrodes Nakane，1983）新异名（替代中根勉和泽田一雄于1956年命名的滑阎甲属（Lioplax Nakane & K. Sawada））。对微埃德蛛属进行了重新描述、绘图，并简要讨论了它与湿阎甲类群其他属的分类关系。重新描述并绘制了4个物种：短跗微埃德蛛（M. brevitarsis (Champion, 1925)）新组合（由土阎甲属（Geodromicus）移入）（印度：北阿坎德邦）、卡斯捷耶夫微埃德蛛（M. kastcheevi）新种（阿尔泰山和准噶尔山脉，哈萨克斯坦东部）、希连科夫微埃德蛛（M. schilenkovi (Zerche, 1992)）新组合（由阿尔泰阎甲属移入）（俄罗斯（阿尔泰山）、哈萨克斯坦）、纤细微埃德蛛（M. subtilis (Sharp, 1889)）新组合（由滑阎甲属移入）（俄罗斯、日本）。克什米尔地区的另一个物种因缺少雄性标本而未命名，并与喜马拉雅地区的短跗微埃德蛛进行了比较。指定了1889年夏普命名的枯草花阎甲（Anthophagus subtilis Sharp）的选模。提出了几个新的组合（所有这些物种之前都被归入滑阎甲属）：黄翅微埃德蛛（M. flavipennis (Watanabe, 1990)）新组合、小型微埃德蛛（M. pullus (Nakane & K. Sawada, 1956)）新组合、点胸微埃德蛛（M. puncticollis (Nakane & K. Sawada, 1956)）新组合、铃木微埃德蛛（M. suzukii (Watanabe, 1990)）新组合、山中微埃德蛛（M. yamanakai (Watanabe, 1990)）新组合。建立了以下新的同物异名关系：纤细微埃德蛛 = 伊图鲁普滑阎甲（L. subtilis iturupensis Lafer, 2004）新异名、 = 洞穴滑阎甲（L. troglophilus Nakane & K. Sawada, 1956）新异名。提供了古北区微埃德蛛属物种检索表。首次绘制了1874年莱康特命名的北美纤细微埃德蛛（M. austinianus LeConte）的口器和阳茎。提供了中亚微埃德蛛属的分布图。希连科夫微埃德蛛首次在哈萨克斯坦被发现。列出了该属的名录。微埃德蛛属目前包含16个物种，其中7个在新北界，9个在古北界。
