Type material: Holotype: male ( IZCAS), Yiling Cave [23º02.374'N, 108º17.529'E, ALT: 151m, T: 23°C, H: 86%], Wuming County, Nanning, Guangxi, China, July 31, 2009, C. Wang & Z. Yao leg. Paratypes: 20 males, 84 females, same data as holotype.

Etymology: The specific name is derived from the Latin word “cordis”, meaning “heart”, and refers to the heart-shaped male palpal bulb; adjective.

Diagnosis: This new species is similar to T. strentarsi Lin & Li, 2010 , but can be distinguished by the presence of six eyes ( Figs 12 View FIGURE 12 A, 13A), the distinctly long, beak-shaped embolus ( Figs 11 View FIGURE 11 A–B, 14A–B), and the semicircular spermatheca of female ( Figs 13 View FIGURE 13 C, 15A).

Description: male (holotype). Total length 1.70 ( Fig. 12 View FIGURE 12 A). Prosoma 0.62 long, 0.60 wide. Opisthosoma 0.90 long, 0.70 wide. Sternum 0.45 long, 0.37 wide. Prosoma, sternum and chelicerae yellow; legs, labium, endites pale yellow. Prosoma nearly triangle, with a pair of setae at the retrolateral side of eyes. Six eyes.

Chelicerae longer than endites, with two teeth and three tiny granulous denticles on the promargin, and three small triangular teeth on the retromargin of fang furrow ( Figs 15 View FIGURE 15 F). Patellae I–IV with one long macroseta on the distal part of dorsal surface. Tibia I–IV with one long macroseta dorsally (position 0.3). Leg measurements: I 5.00 (1.50, 0.25, 1.60, 1.00, 0.65); II 4.17 (1.40, 0.25, 1.10, 0.87, 0.55); III 2.97 (0.90, 0.22, 0.80, 0.55, 0.50); IV 3.90 (1.25, 0.25, 1.12, 0.75, 0.53). Leg formula: I-II-IV-III. Opisthosoma dark green, covered with long setae. Bulb pale yellow, heart-shaped. Embolus long, beak-shaped, and approximately 1.5 the length of bulb ( Figs 11 View FIGURE 11 A–B, 14A–B).

Female (one of the paratypes). Similar to male in coloration and general features, but with a smaller body size and shorter legs. Total length 1.55 ( Figs 13 View FIGURE 13 A–B). Prosoma 0.62 long, 0.60 wide. Opisthosoma 0.75 long, 0.70 wide. Sternum 0.42 long, 0.36 wide. Leg measurements: I 4.80 (1.50, 0.25, 1.45, 1.00, 0.60); II 4.17 (1.25, 0.25, 1.20, 0.87, 0.60); III 2.72 (0.9, 0.20, 0.75, 0.50, 0.37); IV 3.80 (1.25, 0.25, 1.10, 0.70, 0.50). Leg formula: I-II-IV-III. Genital area with a row of setae on epigynal plate and a row of stout setae posterior to epigastric furrow ( Fig. 15 View FIGURE 15 B). Spermatheca elongate, semicircular in lateral view ( Figs 13 View FIGURE 13 C, 15A).

Variation: Total length: males 1.64–1.75 (n = 21), females (1.52–1.60) (n=84).

Distribution: China (Guangxi) ( Fig. 38 View FIGURE 38 ), known only from the type locality.
