Diagnosis.
General body color brownish; acetabula, coxae, trochanters, and basal half of tibiae yellowish; remainder of legs brown. Forewing with a basal white macula starting from humeral angle and ending adjacent to posterior margin of pronotum; at apex a big oval white macula (
Fig. 19
C). Abdominal sternites centrally flattened in males and slightly flattened in females. Male with a pair of distinct projections on posterior margin of sternite VII (
Fig. 19
D) and proctiger with anterior elevation. Paramere elongated, slightly curved centrally, with a small notch on dorsal surface near base, and rounded apex (
Fig. 20
G).
Discussion.
The species was described only from the macropterous form in both sexes. Until now it was known only from the type-locality in
Guyana
, being herein recorded for the first time from
Brazil
. The only specimen examined was collected on a temporary pool in the middle of a trail in a “terra-firme” forest. Males of this species have projections on abdominal sternite VII (19D), and differ from other species with such structures by the maculae pattern of the forewings (
Fig. 19
C). Considering these other species, the apical macula can be smaller (
P. nieseri
), elongated (
P. basalis
), rounded (
P. confusa
), or oval in
P. williamsi
and
P. truxali
. However, the last two species can be easily differentiated by the coloration and shape of the posterior angle of pronotum, being orange and acuminated in
P. truxali
, and brownish and rounded in
P. williamsi
.
