Etymology. Name is derived from the Latin parvus (small), referring to the small depressions of the epigynum.

Diagnosis. Differs from the female of Tylogonus viridimicans (Simon) (see Galiano 1963) and T. yanayacu by the much smaller depressions of the epigynum ( Fig. 116 ). It also differs from T. yanayacu in the shape of the spermatheca ( Fig. 117 ).

Measurements of legs: I 2.8, II 2.5, III 2.8, IV 3.1. Epigynum ( Fig. 116 ): with two very small depressions posteriorly. Vulva ( Fig. 117 ): copulatory duct thin and short; spermatheca almost oval. Color in alcohol ( Fig. 115 ): carapace brownish, with iridescent green scales; abdomen brown with many iridescent green scales and an indistinct dark brown marking; legs pale yellow.
