( Figs 17–31View FIGURE 17–24View FIGURE 25–31)

Type material. Holotype male (DQ-001), Benzilan Town , Deqin County, Diqing County , Yunnan Province, China, 28.2441°N, 99.2989°E, 2117 m, 13 July 2016, collected by Zizhong Yang; deposited at NZMC, Institute of Zoology , Chinese Academy of Sciences, Beijing, ChinaGoogleMaps  .

Etymology. The species epithet, a noun in apposition, refers to the type locality.

Diagnosis. The male of C. deqin  sp. nov. can be distinguished from all other Conothele  species by embolus with a small fish-hook tooth at its tip ( Fig. 28 View Figure ), from C. cangshan  sp. nov. by the sperm duct, which is thicker than that of the latter in retrolateral view ( Fig. 31 View Figure ).

Carapace black, strongly sclerous, glabrous ( Fig. 25 View Figure ). Caput arched. Fovea deep and dark, procurved and U-shaped.

Palpal bulb simple, embolus elongated and slender ( Figs 29–31 View Figure ), with a small fish-hook tooth at its tip, cymbium dorsal with 5 clavate, 4 filiform and 12 broken trichobothria ( Figs 28, 30 View Figure ).

Distribution. Yunnan Province (Diqing County), China.

Remarks. We preliminarily treat the male collected in Deqin, Yunnan Province as a different species ( C. deqin  sp. nov.) from female C. yundingensis  found in Tengchong, Yunnan Province for the same reason given above. Two species are geographically isolated by the long distance (c. 300 km apart) and two large rivers, Lancangjiang and Nujiang. The species is known only from male specimens.
