The genus Xenasterides Newton, 2017 is considered here as a junior synonym of Pseudastenus Bernhauer, 1933, both monotypic and Neotropical genera of Paederinae (Staphylinidae). A thorough description of the genus is provided. The species Pseudastenus barretoi Bernhauer, 1933 and P. plaumanni (Bierig, 1939) are redescribed and illustrated, six new species are described, and a dichotomous key is available for species. These new species are: P. amazonicus, P. ferrugineus, P. latus, P. oculatus, P, ribeirocostae, and P. schubarti.
这里将2017年的Xenasterides牛顿属视为1933年的Pseudastenus贝氏属的次异名，二者均为隐翅虫科（埋葬虫科）的单型属且分布于新热带区。文中对该属进行了详尽描述。重新描述并配图展示了1933年的巴氏Pseudastenus贝氏属和1939年的P. plaumanni（比里希），描述了六个新物种，并提供了物种的二歧检索表。这些新物种分别是：亚马逊Pseudastenus贝氏属、铁锈色Pseudastenus贝氏属、宽体Pseudastenus贝氏属、眼状Pseudastenus贝氏属、里贝罗肋骨Pseudastenus贝氏属和舒巴尔蒂Pseudastenus贝氏属。
