Pseudocneorhinus setosus Roelofs, 1879: liii (original description); Marshall 1934: 9 (note); Voss 1956: 24 (note); Han et al. 2000: 35 (Korean fauna); Borovec 2009: 76 (check-list); Borovec 2013: 418 (catalogue); Morimoto et al. 2015: 334 (Japanese fauna); Alonso-Zarazaga et al. 2017: 403 (catalogue).

Type material examined.

This species was described from an unspecified number of specimens from “Japon”. We have studied one probably female specimen, well preserved and 4.88 mm long, deposited in Marshall’s collection (BMNH), with the labels: Type [printed, circular label with red margin] / Japan G. Lewis 1910-320. [printed] / Lewis [handwritten] / Pseudocn. setosus R. Japon L. [handwritten].

Material examined.

Other material. CHINA - Fujian Prov. 1 ♀; Kuatun; Jun. 1946; Tschung Sen leg.; RBSC.

JAPAN; 1 ♀; Nagasaki; BMNH.

Remarks.

Morimoto et al. (2015) split P. setosus to two species, P. setosus and his newly described P. squameus . Morimoto studied only Japanese material, but he cited for both species the original distribution of P. setosus - Japan, Korea and China. Material cited in earlier literature must therefore be revised to check the identity of the specimens. The species can be distinguished by their elytral setae and also by the different shape of the spermatheca. However, we can not confirm that elytral setae are a stable distinguishing character, because material from places other than Japanese islands seems to be variable in this character, but the spermatheca seems to be useable. Based on the spermatheca, we can confirm the occurrence of the both species, P. setosus and P. squameus , in China.
