Type material examined.

Holotype ♂ (IZCAS-Ar40604), China: Yunnan: Xishuangbanna, Mengla County, Menglun Town, XTBG, tropical rainforest (21°55.20'N, 101°16.21'E, ca. 550 m), 30.iv.2019, Y. Tong leg. Paratype 1♂ (IZCAS-Ar40605), same data as holotype.

Other material examined.

1♀ (IZCAS-Ar42566), same data as holotype ; 1♀ (IZCAS-Ar42567), same locality, 07.viii.2018, C. Wang leg.

Diagnosis.

The male was thoroughly diagnosed in Wang and Li (2020b). The female of this species closely resembles that of C. chichila Logunov, 2003 in having a similar epigyne, but it differs in the following: 1) the basal epigynal plate has a bow-shaped posterior margin (Fig. 1A ) vs. V-shaped margin in C. chichila ( Logunov 2003: figs 3, 4); 2) the copulatory ducts are connected to the spermathecae laterally (Fig. 1B ) vs. connected dorsally to the posterior edges of the spermathecae in C. chichila ( Logunov 2003: figs 5, 6).

Description.

Male. Complete description in Wang and Li (2020b).

Female (Fig. 1A, B, D, E ). Total length 3.24. Carapace 1.59 long, 1.23 wide. Abdomen 1.54 long, 1.21 wide. Clypeus 0.09 high. Eye sizes and inter-distances: AME 0.37, ALE 0.24, PLE 0.21, AERW 1.20, PERW 1.18, EFL 0.74. Legs: I 2.76 (0.85, 1.10, 0.48, 0.33), II 2.42 (0.83, 0.93, 0.33, 0.33), III 3.06 (1.03, 1.05, 0.65, 0.33), IV 3.19 (1.03, 1.05, 0.78, 0.33). Carapace yellow-brown to dark brown, covered with brown and white, thin setae. Fovea red-brown, bar-shaped, longitudinal. Chelicerae red-yellow. Endites broadened meso-distally, pale ental margins. Labium darker than endites, paler distally. Sternum nearly shield shaped, yellow-brown, with thin, brown setae. Legs yellow to yellow-brown. Abdomen oval, dorsum gray-brown, with irregular pale dots and transverse stripes posteriorly, covered with short, thin setae; venter brown, laterally with a pair of pale longitudinal stripes extending from epigastric furrow to terminus.

Epigyne (Fig. 1A, B ): wider than long; basal plate almost equal in width to epigyne, with a bow-shaped posterior margin; copulatory openings C-shaped, located laterally; copulatory ducts curved almost 180° medially, connected to spermathecae laterally; spermathecae almost square, touching medially; fertilization ducts anterior to spermathecae.

Distribution.

China (Yunnan).

Comments.

The pairing of this species with the female is supported by DNA barcoding (unpubl. data).
