Treatment

Cicurina dong Li View in CoL , sp. nov. ( Figs 69–72 View Figure 69 View Figure 70 View Figure 71 View Figure 72 , 97 View Figure 97 )

Type material. Holotype. Male, China, Guizhou, Bijie City , Zhijin County, Chengguan Town , Yangliu Village , Long Cave , 26°40.975´N, 105°47.085´E, elev. 1323 m, 24 April 2007, Y. Lin & J. Liu leg., deposited in IZCAS GoogleMaps . Paratypes. 2 males, 30 females, same data as holotype, deposited in IZCAS GoogleMaps .

Etymology. The specific name is from the Chinese word for cave, in reference to the habitat of this species; noun.

Diagnosis. The male pedipalpus of this species closely resembles that of C. medina Gertsch, 1992 (Paquin & Dupérré, 2009: 31, figs 56–57), but can be distinguished by the presence of a finger-shaped apophysis at retrolateral margin of TA (absent in C. medina ). Females of this species are most similar to those of C. avicularia Li , sp. nov. ( Figs 64 View Figure 64 , 66A–D View Figure 66 ), but can be distinguished by the anteriorly situated BO (posteriorly situated in C. avicularia Li , sp. nov.), and the end of copulatory ducts pointing laterally (posteriorly pointing in C. avicularia Li , sp. nov.).
