Etymology. The specific name is a noun in apposition that refers to the type locality of most of the type specimens: the Parque Nacional de Sete Cidades in the municipality of Piracuruca , Piauí, Brazil.

Diagnosis. Quemedice piracuruca n. sp. is distinguished from Q. enigmaticus by the male palp with different size RTA branches, ventral one short and truncated, dorsal twice as long and distally pointed ( Fig. 13 ), embolus base with small teeth retrolaterally and medially widened ( Figs 13–14 ); female epigynum with slen- der median field, at least three times longer than wide, vulva with smaller and slender hyaline receptacles and wider convoluted copulatory ducts ( Figs 15–16 ).
