Females resemble  Stemmops carius(vide Marques & Buckup, 1996, figs. 7–8) by the presence of oval spermathecae, ventral epigynum with a narrow and elongated longitudinal median depression and coiled fertilization ducts, but differ by the spermathecae less separated from each other, in ventral view ( Figs. 2, 3).   Description. Male holotype(from Estação Ecológica de Murici, IBSP 215203): Total length 1.57.
