Etymology. The specific name derives from the Latin adjective echinatus and means spiny, in reference to the cymbium with a strong spine.

Diagnosis. The new species is very similar to T. albioculum , but can be distinguished by having the median apophysis with a process and the conductor membranous.

Male (measurements of holotype). Total length 3.20. Prosoma 1.30 long, 1.23 wide, flat, pale yellow, with black
