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
A, 13A), the distinctly long, beak-shaped embolus (
Figs 11
A–B, 14A–B), and the semicircular spermatheca of female (
Figs 13
C, 15A).
Description: male (
holotype
).
Total length 1.70 (
Fig. 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.

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
B). Spermatheca elongate, semicircular in lateral view (
Figs 13
