Trisinus Raffray, 1894 View in CoL

Chinese common name: 幻Ɵà甲¤

Trisinus Raffray, 1894b: 265 View in CoL . Type species: Trisinus cratocerus Raffray, 1894b: 265 View in CoL (designated by Lucas 1920: 657).

= Batrisoplisus Raffray, 1908: 180. Type species: Batrisus antennatus Weise, 1877: 97 (monotypy). Synonymized by Yin et al. 2012c: 62.

Trisinus was synonymized with Batrisoplisus by Yin et al. (2012c), and is currently defined by the presence of an oblique inner pair of carinae on tergite 1 (IV), and the unique form of the aedeagus. The males of most described species have characteristically modified antennae, but the new species described here possesses a modified tergite 2 (V).

The genus is represented by 26 species distributed in Japan (21 spp., including the Ryukyu Islands ), China (3 spp. in Yunnan), Singapore ( 1 sp.), and Indonesia ( 1 sp. in Sumatra) ( Newton 2018). The first species from Tibet is described here .
