Etymology.
The specific name is an adjective from the Latin word
oculatus
(eye-shaped), and refers to the anterior part of the epigynal atrium with a pair of eye-shaped depressions.

Diagnosis.
This species can be separated from other congeneric species by the
epigynum
, particularly the pair of eye-shaped depressions and the twisting of the copulatory ducts. The male can be separated from other congeneric species by the shape of the RTA (
Figs 11
B–D, 12A–B).
