Coriojassus yunnanensis sp. nov.

( Fig. 1 I, J, 9A–G)

Coloration and external morphology ( Fig. 1 I, J) as in C. zhejiangensis . Male 7.5 mm long, 3.5 mm wide across humeral angles. Male pygofer with caudal margin slightly concave in lateral view, ventral process subtruncate apically with angulate ventroapical projection ( Fig. 9 A). Subgenital plate with dorsolateral margin broadly convex, apex obliquely truncate ( Fig. 9 B). Style apophysis more than twice as long as apodeme, sharply bent at acute angle near midlength, apex footlike ( Fig. 9 C). Aedeagus with shaft curved dorsally at base, then linear to apex ( Fig. 9 F); stem of distal processes absent, lateral projection adjacent to gonopore, subapical teeth absent ( Fig. 9 D, E).

Material examined. China: Holotype ♂, Yunnan, Menglun, 20.v. 2009, 600m, Wei Cui [ NWAU].

Notes. This species is very similar to C. zhejiangensis sp. nov., but differs in having the stem of the paired distal processes absent and in lacking lateral teeth on the aedeagal shaft basad of the gonopore. The species name is based on that of the Chinese province in which the holotype was collected.
