Material examined.

BRAZIL. Locality not specified further, male holotype of Gonyleptes pustulatus , examined from photo (ZMUC). São 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 .
