(Fig. 6)

Male 2S abdominal apodemes (Fig. 6k) broad, exceeding anterior margin of 4th sternite.

Pygofer dorsal appendage (Fig. 6a) short and thin, not reached hind margin of pygofer side, almost with even thickness, straightly directed ventro-caudad. Subgenital plate (Figs 6d, e) slightly curved dorsad in lateral view, much longer than style. Style (Fig. 6f) with apical part slightly bent laterad. Aedeagal shaft (Figs 6h–j) broadened basally and sharply narrowing subbasally, apical 3/4 almost equal in thickness, apical process long and extremely straight; dorsal apodeme long, preatrium short but broad in lateral view.

Measurement. Length male 4.10mm.

Material examined. Holotype: ♂, China, Yunnan Prov., Pingbian, 1300m, light trap, 15 vi 2009, coll. Cui Wei.

Deposition. Entomological Museum, NWAFU, Yangling, China.

Remarks. The new species resembles C. latiprocessa sp. n., but the style is slightly curved apically, the connective is longer and the manubrium parallel-sided, the aedeagal shaft has the apical process extremely straight and without subapical fingerlike processes, and the preatrium is broader.

Etymology. The specific name is derived from the Latin prefix “ ortho -” and Latin word “ processus ”, referring to the straight apical process of aedeagus.
