Holotype
:

), Diamond Cave [8°04'01.34ʺN, 98°54'59.11ʺE], Krabi Province,
Thailand
,

Etymology.
The specific name is derived from the Latin word “anguis”, meaning “snake”, and refers to the snake-shaped embolus; adjective.
Diagnosis.
This new species is similar to
T. strentarsi
(see
Lin & Li, 2010
), but can be distinguished by the presence of six eyes, the snake-shaped embolus (
Figs 4
A–B, 5A–B) in the male, and the long, tube-shaped, spiral spermatheca (
Figs 4
C, 7A–B) in the female.
