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).

Ocular area grayish black with grayish white scales. Eye measurements: AME 0.09, ALE 0.21, PME 0.19, PLE 0.19, AME-AME 0.12; AME-ALE 0.07; PME-PME 0.31; PME-PLE 0.32. Eye row width measurement: I 0.27, II 0.64, III 1.15, IV 0.64. Clypeus height 0.52. Sternum light yellow; chelicera yellow, labium and endites brown, chelicera with 2 pro- (1 large, 1 small) and 1 small retromarginal teeth. Legs yellow with long spines. Leg measurements: I 9.60 (2.80, 3.50, 2.20, 1.10); II 8.70 (2.60, 3.20, 2.00, 0.90); III 6.75 (2.00, 2.40, 1.60, 0.75); IV 6.95 (2.20, 2.25, 1.70, 0.80), leg formula: 1243. Opisthosoma anteriorly with yellow spots, posteriorly with yellow chevrons; laterally with grayish black stripes; ventrally grayish.
Epigynum (Figs 10 B–C, 12C–D). Epigynum with a pair of depressions anteriorly, copulatory ducts twisted, spermathecae globular.

Eye measurements: AME 0.08, ALE 0.20, PME 0.18, PLE 0.17, AME- AME 0.11; AME-ALE 0.06; PME-PME 0.25; PME-PLE 0.28. Eye row width measurement: I 0.27, II 0.57, III 1.10, IV 0.56. Clypeus height 0.40. Leg measurements: I 9.60 (2.60, 3.50, 2.30, 1.20); II 8.85 (2.50, 3.20, 2.15, 1.00); III 7.00 (2.00, 2.40, 1.80, 0.80); IV 7.10 (2.10, 2.20, 1.90, 0.90), leg formula: 1243.
