Figs 13–14 , 69

Neriene calozonata Chen & Zhu, 1989: 162 , f. 12–18 (Df); Song, Zhu & Chen, 1999: 193, f. 108I–J (f); Yin et al., 2012: 519, f. 243a–c (f).

Material examined. Hubei: Shennongjia Forestry District, Yanzidong Cave , 31.72°N, 110.47°E, 2000m, 7.viii.1986, J. Chen leg., 2FF (CBEE).

Diagnosis: This species is similar to Neriene compta Zhu & Sha, 1986 and Neriene nitens Chen & Zhu, 1991 in having the large atrium opening, similar copulatory grooves which have about one and a half coils, but can be distinguished from the latter two species by the following characters: both spermatheca and turning-point long, slender, significantly curved in N. compta and N. nitens , but just slightly long and curved in N. calozonata ( Figs 13 , 14 B–C, 47A–C, 49C–E).

Description of female: The measurements see Chen & Zhu, 1989. Epigynum ( Figs 13A , 14B ): In ventral view, atrium opening large. Parmula arising from dorsal wall, semicircular with rounded tip, and with a small semicovered depression on its ventral surface. Vulva ( Figs 13B , 14C ): Vulva as long as wide; copulatory grooves started mesally, with about one and a half coils; fertilization grooves enter the spermathecae, with about one and a half coils; turning-points situated laterally, pointing towards mesally; spermathecae slender, pointing towards laterally. Female habitus as in Fig. 14A .

Male: Unknown.

Distribution: China (Hubei) ( Fig. 69 ).
