Type material.

Holotype ♂ (HNU-CASENT 9022600) and paratypes 2♂ 6♀ (HNU-CASENT 9022360), China: Yunnan Province, Lushui County, Pianma Township, Changyan River, 9.3 km ESE Pianma, mixed broadleaf deciduous and evergreen forest, dusting small webs near ground in forest understory (25.99363°N, 98.66651°E; 2470 m), 13-15.V.2005, C. Griswold leg. Examined.

Other material examined.

21♂ 93♀ (NHMSU-HA113), China: Yunnan Province, Lushui County, Pianma Town, Changyan River, mixed broadleaf deciduous and evergreen forest, dusting small webs near ground in forest (25.99363°N, 98.66651°E; 2470 m), 10.VIII.2018, Y. Lin et al. leg.; 1♂ (NHMSU-HA113) and 1♀ (NHMSU-HA113) used for sequencing, GenBank: MT992009 and MT992008, same data as for preceding.

Diagnosis.

The male of C. pianma is similar to C. quanqu in the form of the palp but can be distinguished from the latter by the subquadrate median apophysis with a hooked process, rather than a subtriangular median apophysis with a truncated process (Figs 19A, B , 23A, B ). The female of C. pianma seems closest to that of C. bangbie sp. nov. but differs by the more slender, more twisted copulatory ducts than in the latter, and the smaller copulatory openings (Figs 19E-G , 3E-G ).

Description.

See Miller et al. (2009).

Distribution.

China (Yunnan) (Fig. 38 ).
