Two New Species of Batrisini (Coleoptera: Staphylinidae: Pselaphinae) from Nanling Mountain Area, China

Simple Summary The Nanling Mountains are the largest mountain range and an important physical geographical boundary in Southeast China, but their insect diversity has not been sufficiently documented up to now. Through recent investigations of the local staphylinid fauna at Nanling, more than 4500 adult pselaphine beetles were collected and most of the samples belong to the highly diverse tribe Batrisini. Here, two new species of the genera Batrisceniola and Physomerinus, both poorly represented in the Chinese pselaphine fauna, are described. Two new species of the Batrisocenus complex of genera, e.g., Batrisceniola nanlingensis sp. nov. and Physomerinus clavipes sp. nov., are described, diagnosed, and illustrated from the Nanling Mountain Area. Both represent a second species of the respective genus from the Chinese mainland.
