Pseudocneorhinus alternans Marshall, 1934: 7 (original description); Borovec 2009: 76 (check-list); Voss 1956: 24 (note); Borovec 2013: 418 (catalogue); Alonso-Zarazaga et al. 2017: 403 (catalogue).

Type material examined.

The original description was based on material from "China: S. Kansu, 1 ♀, 26.vi.1930, 1 ♀, 4.x.30 (Dr. Hummel)". There is one specimen lacking head with rostrum in Marshall’s collection (BMNH) pinned on very slender and short paper label. This specimen is labelled as follows: Cotype [printed, circular label with yellow margin] / Kina S. Kansu [printed] / Sven Hedins Exp. Ctr. Asien Dr Hummel [printed] / Pres. by Imp. Inst. Ent. B. M. 1934-130. [printed] / 4/10 [handwritten] / Pseudocneorrhinus alternans Mshl. COTYPE ♀ [ Marshall’s handwriting]. We have not designated the examined syntype specimen as lectotype in the view of the fact that it is incomplete and the species was described from two specimens.
