Pselaphodes spinosus Champion, 1925

( Figs 16B , 18 )

Pselaphodes spinosus Champion, 1925: 261 .

= Labomimus championi Jeannel, 1960: 454 . (comb. & syn. nov. in YIN & LI 2015: 340).

Type material examined. See YIN & LI (2015: 340).

Additional material examined. CHINA: 2 ♁♁, ‘China: Tibet, Rikaze, Jilong, 28°16’39.98” N, 85°22’36.21” E, 1700 m, 29-31.vii.2017, Qiu & Xu leg. [ MDH ṞNJẘợḦÁIJ]’ ( SNUC).

Supplementary description of additional material. Male ( Fig. 16B ). Antennomere X ( Fig. 18A ) strongly concave at middle, metaventral processes long, emarginated at apices. Length of aedeagus ( Figs 18 B–C) 0.63 mm. Each eye composed of about 40 facets. Measurements: BL 3.61–3.68 mm, HL 0.73–0.78 mm, HW 0.71–0.72 mm, PL 0.77–0.78 mm, PW 0.71–0.73 mm, EL 1.06–1.16 mm, EW 1.35–1.40 mm, AL 1.00– 1.02 mm, AW 1.37–1.41 mm.

Comments. Male of this species has a unique antennomere X which is distinctly constricted at its middle. Combined with the nearly identical form of the aedeagus and close distribution, the population from Xizang can be readily identified as conspecific with that from the type locality.

Distribution. China: Xizang (new country record); India: Uttarakhand.
