5F2FC3639D19A66F469095DAFC36FF4B.taxon	diagnosis	Diagnosis of male. The new species is distinct among its Palaearctic congeners by possessing enlarged and flattened pedicel in the male, which is about four times as long as antennomere III. When combined with the frontal modifications (Fig. 4 A) and aedeagus (median lobe apically expanded; Fig. 4 F), it can be readily separated from all other European and East Asian species.	en	Jiang, Ri-Xin, Yin, Zi-Wei (2016): Two new species of Batrisodes Reitter (Coleoptera: Staphylinidae: Pselaphinae) from China.
