Contributions to the knowledge of the "Staphylinus-complex" (Insecta: Coleoptera, Staphylinidae, Staphylinini) of China. Part 20. The genus Wasmannellus Bernhauer, 1920. Section 2

Abstract

The genus Wasmannellus was established by Bernhauer (1920: 186) to include a single species, W. tristis, from Sikkim (Darjeeling). The genus was redescribed and redefined by Smetana (2006). Not only has W. tristis remained the sole species of the genus until now, but also the holotype is still the only known specimen of the taxon. It was, therefore, a rather pleasant surprise that in some recently collected Chinese Staphylinina submitted for identification, a series of specimens was found that turned out to represent a second species of the genus Wasmannellus. The specimens displayed all the important character states defining Wasmannellus, including the puncture bearing the postocular seta on the head being situated closer to posterior margin of head than to posterior margin of eye (Fig. 2).
