Abdomen: length 4.52, epigastric furrow 0.83 from tracheal spiracle, spiracle 3.07 from base of spinnerets. Epigynum: atrium longer than wide, cylindric-shaped, rounded posteriorly; lateral borders thin, sclerotized, laminar; internally with very long, thin copulatory ducts, curved at medial region; seminal receptacles small and rounded, sub-medially situated on the copulatory ducts; spermathecae large, ovalshaped, posteriorly positioned; fertilization ducts almost as long as the spermathecae (Figs 2B, C).
