Sinopoda yanzi Wang & Li View in CoL sp. nov. Figures 7A-F View Figure 7 , 8A, B View Figure 8 , 9I, J View Figure 9 , 10 View Figure 10

Material examined.

Holotype ♂ (IZCAS-Ar41615), China, Hunan Province, Huaihua City, Chenxi County, Huomachong Town, Yanzi Cave; 27.8545°N, 110.2605°E; 408 m; 6 Sept. 2019, Ziyi Wang & Zhigang Chen leg. Paratype 1 ♀ (IZCAS-Ar41627), same data as holotype, but 18 Mar. 2016; Yulong Li & Zhigang Chen leg. 1 ♀ (IZCAS-Ar41628), same data as holotype, 6 Sept. 2019; Ziyi Wang & Zhigang Chen leg.

Diagnosis.

The male of this new species is similar to Sinopoda tumefacta Zhong, Jäger, Chen & Liu ( Zhong et al. 2019: 69, figs 53A-E, 54A-F, 55A-D) in the shape of conductor, but it can be distinguished by the following: the dRTA is sharp, short, and triangular, while the dRTA is long and an irregular-quadrilateral in S. tumefacta ; the vRTA is smooth in ventral view (Fig. 7A-D View Figure 7 ), while the vRTA is concave in ventral view in S. tumefacta . The female of this new species is similar to S. dehiscens Zhong, Jäger, Chen & Liu, 2019 ( Zhong et al. 2019: 28, figs 20A, B, 21A-D) in having an analogous lobal septum and lateral lobes, but it can be separated by the following: the middle part of lateral lobes has a downward protrusion but there is no protrusion in S. dehiscens ; the anterior part of the internal ducts is not fused with the median line, while in S. dehiscens the ducts are distinctly divided; the glandular appendages are wider than the posterior parts of the internal duct system in this new species, but the glandular appendages are as wide as the posterior parts of internal duct system in S. dehiscens ; the posterior parts of internal duct system are swollen and slightly divided, while they are distinctly separated posterolaterally in S. dehiscens ; this new species has fusion bubbles medially on the lobal septum, but S. dehiscens has no fusion bubble (Fig. 8A, B View Figure 8 ).

Chelicerae deep reddish brown. Legs: yellowish brown. Opisthosoma: dorsally dark reddish brown, covered with dark hairs, with bright bands in anterior part; ventrally yellowish brown with bright band on both sides of central axis. Spinnerets yellowish brown (Fig. 7E, F View Figure 7 ).
