Material examined.
BRAZIL. 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
.
