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

Two New Species of the Genus Petaloscapus Jeannel, 1958 (Staphylinidae: Pselaphinae) from Tsushima and Gotô Islands, Kyushu, Japan

“…It is easily distinguished by the prolonged antennomere 1 in the inner apex, the median nodule on the clypeus and the strongly processed antennal tubercles on the frons in the male. The genus is mostly allied to the genus Batrisodellus Jeannel, 1958 (recently synonymized with Batrisodes Reitter, 1882 by Yin et al 2015) in having the stout body, the pronotum with a pair of hook-like spines on the dorsal side, the elytra each with three basal foveae and the abdominal tergite IV with a pair of triangular paratergites in dorsolateral sides. However, it is distinct in the structure of male genitalia formed by subcylindrical median lobe with asymmetrical, lamellar projection(s) at apex, and endophallus consisting of some asymmetrical sclerites.…”

Eight new species of Batrisodes Reitter from China (Coleoptera, Staphylinidae, Pselaphinae)

“…Eleven species of the genus Batrisodes Reitter are currently known to occur in China, scattered in Zhejiang, Hunan, Sichuan, Yunnan, Xizang (Tibet), Ningxia, and Taiwan (Besuchet 1981; Nomura 2007; Yin and Li 2013; Yin et al 2011, 2015; Jiang and Yin 2016). This number is apparently at a low level in contrast to the 150 described species in the Holarctic region (Chandler 1997; Schülke and Smetana 2015).…”
