The specific name is a noun in apposition, from the Brazilian expression “do balacobaco ”. This expression denotes that something is excellent and problably had a Bantu origin. Diagnosis. Males of Corinna balacobaco n. sp. differ from those of other species with a small median projection on prolateral surface of RTA by the tapered apex of RTA, embolus short, bent in right angle and by the strongly sclerotized conductor ( Figs. 83–84 ); females are readily recognized by the copulatory opening inserted in a ventral triangular epigynal projection ( Fig. 85 ).
