The tribe Placusini (Coleoptera: Staphylinidae) consists five genera with worldwide distribution. Despite great morphological diversity, the species are easily recognized by their 4-4-5 tarsal formula and the two-articulated labial palpi, along with a broad and rounded ligula. Several synapomorphies proposed by earlier authors, both for larvae and adults, have led to the conclusion that the tribe now is considered monophyletic within Aleocharinae. Herein, a new genus and species of Placusini from Brazil is described and illustrated. Euryachen seuzei gen. et sp. nov. presents all the proposed synapomorphies for the tribe, in addition to unique characters. An updated key for the genera in Placusini is also provided.
普拉库斯尼族（鞘翅目：隐翅虫科）由五个属组成，分布于世界各地。尽管形态差异很大，但该族物种很容易通过其4-4-5跗节式、双节唇须以及宽阔圆润的叶舌来识别。早期作者提出的一些幼虫和成虫的共同衍征，使得该族现在被认为在隐翅虫亚科内是单系的。在此，描述并图示了来自巴西的普拉库斯尼族一个新属和新物种。新属新种苏泽宽腹隐翅虫（Euryachen seuzei gen. et sp. nov.）除具有该族所有已提出的共同衍征外，还有独特特征。还提供了普拉库斯尼族各属的最新检索表。
