Locality not specified further, male holotype of Gonyleptes pustulatus , examined from photo (ZMUC). Sao Paulo: Santos, male holotype of Gonyleptes guttatus (SMF 1321). Rio de Janeiro: Casimiro de Abreu, 5 ♂ & 6 ♀ (MNRJ 17456). Diagnosis. Gonyleptes pustulatus (Fig. 12 A-B ) superficially resembles Gonyleptes bimaculatus because of the conspicuous white patches on mesotergum. Males of Gonyleptes pustulatus can be distinguished from Gonyleptes bimaculatus by: femur IV armed (unarmed in Gonyleptes bimaculatus ) and presence of a bifid retrolateral apical apophysis on coxa IV. Description. Penis (Fig. 12 C-D ; MNRJ 17456): ventral plate with slightly inflated middle region, a deep distal U-cleft on anterior margin (its distal tips are divergent), 3 distal pairs of long, curved setae, 1 median pair of short setae, 4 basal pairs of spatulate setae. Stylus slightly straight, with apex slightly swollen. Ventral process robust, apex flabelliform with serrated and rounded distal margin. Taxonomical note. Gonyleptes pustulatus is a remarkable species by body color pattern. It was described without any illustration. Probably this was the reason that kept this species virtually unknown and led Roewer to describe Gonyleptes guttatus . Figure 12. Gonyleptes pustulatus Sorensen .
