Atrocalopteryx auco Hämäläinen, spec. nov. (holotype ♂, from Vietnam, Lang Son province, Huu Lien, Tan Lai, alt. 260 m, 9 June 2008, deposited at RMNH, Leiden, The Netherlands) is described and illustrated for both sexes and compared with other species in the genus. The new combination Atrocalopteryx laosica (Fraser, 1933), comb. nov. is made. An annotated list of Atrocalopteryx species and keys to both sexes are presented. Male of A. auco differs from the other two completely opaque-winged species (A. atrata and A. atrocyana) by having yellowish crossveins on the under surface of the wings and by having the underside of abdominal segments 8-10 strikingly yellowish. The female of A. auco can be easily separated from A. atrata and A. atrocyana by the presence of whitish pseudopterostigma in both wings. Problems in the definition of the genus Atrocalopteryx are discussed.
奥氏阿克罗蟌，新物种（正模♂，采自越南谅山省渭川县潭来，海拔260米，2008年6月9日，保存于荷兰莱顿的荷兰国家自然历史博物馆），本文对其雌雄两性进行了描述和图示，并与该属其他物种进行了比较。提出了新组合老挝阿克罗蟌（弗雷泽，1933年），新组合。列出了阿克罗蟌属物种的注释清单以及两性的检索表。奥氏阿克罗蟌雄虫与其他两种完全不透明翅的物种（黑阿克罗蟌和黑蓝阿克罗蟌）不同，其翅下表面有淡黄色横脉，腹部第8 - 10节腹面显著淡黄色。奥氏阿克罗蟌雌虫可通过双翅均有白色假翅痣而容易地与黑阿克罗蟌和黑蓝阿克罗蟌区分开来。文中讨论了阿克罗蟌属定义中的问题。
