Etymology. The specific name is and adjective from the Latin word pilulifera (small-ball-shaped), and refers to the shape of the spermatheca.

Diagnosis. This species can be separated from other congeneric species by the large RTA in the male palpus and the very small spermatheca of the females.

Eye row width measurement: I 0.28, II 0.70, III 1.15, IV 0.68. Clypeus height 0.56. Sternum light yellow; chelicera, labium and endites light brown, chelicera with 2 pro- (1 large, 1 small) and 1 small retromarginal teeth. Legs grayish brown with long spines.

Opisthosoma dorsally grayish yellow with grayish black spots; ventrally gray with grayish black marking.

Epigynum ( Figs 17 B–C, 19C–D). Epigynum atrium wider than long, copulatory openings visible, spermatheca smaller than copulatory ducts.
