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); 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).
