Crassignatha quanqu Miller et al., 2009: 72, figs 76E-G, 78F, 79E, F, 83A-E, 84A, B, 85A-F (♂♀).

Type material.

Holotype ♂ (HNU-CASENT 9029323) and paratypes 1♂ 1♀ (HNU-CASENT 9022388), China: Yunnan Province, Longling County, Zhen’an Township, Bangbie Village, at stream at km 6.8 on Route S317, shady embankments along stream, dusting webs in understory (24.81333°N, 98.83280°E, 1552.5 ± 7.5 m), 24.V.2005, C. Griswold leg. Examined.

Diagnosis.

The male of Crassignatha quanqu is similar to C. gucheng sp. nov. but can be distinguished by the median apophysis with two tapered distal processes and the details of the palp (Fig. 23A-C vs. Fig. 10A-C ). The female of C. quanqu is similar to C. yinzhi and C. thamphra sp. nov. in the vulva configuration, but differs by the nearly vertical connection of copulatory ducts and copulatory openings, rather than connected diagonally as in the latter two, and differs by the fertilization ducts starting at the posterior margin of the spermathecae, rather than the inside medial margin as in the latter two (Fig. 23D, E vs. Figs 32F, G , 37F, G ).

Description.

See Miller et al. (2009).

Distribution.

China (Yunnan) (Fig. 38 ).
