Two new species of Batriscenellus Jeannel from tropical Asia (Coleoptera: Staphylinidae: Pselaphinae)

The genus Batriscenellus Jeannel is recorded from Southeast Asia for the first time, with two species described as new: B. suthepensis Yin Kleeberg, sp. nov. from Chiang Mai, Thailand, and B. vietnamicus Yin Kleeberg, sp. nov. from Vinh Phuc, Vietnam. The male of both new species can be readily separated from those of all congeners by the unique shape of the modification on tergites 1 (IV), as well as the structure of the aedeagus.
