New species and new combinations of Asian Batrisodes Reitter (Coleoptera, Staphylinidae, Pselaphinae), and synonymy of Batrisodellus Jeannel with Batrisodes

Continuing surveys on the pselaphine fauna in China have revealed four undescribed species of the genus Batrisodes: Batrisodesangustelytratussp. n. (with Pachycondyla ant) and Batrisodeslongwangshanussp. n. from Zhejiang, Batrisodesbamiansp. n. (with Pseudolasius ant) from Hunan, and Batrisodessongxiaobinisp. n. (with Formica ant) from Yunnan. The genus Batrisodellus is placed as a junior synonym of Batrisodes, syn. n.; this taxonomic act results in eight new combinations:Batrisodescerberus, Batrisodescoprea, Batrisodescristatus, Batrisodesfengtingae, Batrisodeslaticollis, Batrisodeslongulus, Batrisodespalpalis, and Batrisodespunctipennis. The Russian Far East species Basitrodescornutus is transferred to Batrisodes, comb. n.
