Diagnosis. Quemedice enigmaticus   is distinguished from Q. piracuruca   n. sp. by the male palp with RTA branches similar in size (sometimes dorsal branch slightly shorter) and base of embolus smooth ( Figs 8–10 View FIGURES 8 – 16. 8 – 12 ); female epigynum   with broad median septum, twice longer than wide, and vulva with large, elongate hyaline receptacles and slender, convoluted copulatory ducts ( Figs 11–12 View FIGURES 8 – 16. 8 – 12 ).
