Diagnosis. General body color brown to dark brown; femora yellowish on basal half and brown on apical half; ventrally with silvery setae on basal half; tibiae brownish with a basal and an medial yellowish ring. Anterior lobe of pronotum with a pair of reniform whitish maculae; posterior lobe between humeral angles with a distinct conical projection ( Fig. 15 A). Forewing with a basal white macula, elongated and narrow, starting from humeral angle and ending at posterior lobe of pronotum; at apex other three white maculae, the central being strongly convex and the lateral ones small and rounded ( Fig. 15 A). Small black denticles on inner surface of fore and hind tibiae. Intersegmental region between meso- and metasternum without small tubercles. Intersegmental region of connexives with silvery setae. Anterior margin of abdominal sternites III–VII with a transverse area without setae, becoming larger towards apex (as in Fig. 5 B). First genital segment of male with posterior margin slightly convex dorsally. Male proctiger without dorsal projection. Paramere without setae, narrow on base, tapering towards apex, which is rounded ( Fig. 16 E).

Discussion. This species is known only from the macropterous form and previously recorded only by the original description from French Guiana and Pará State, Brazil. Its geographical range is herein extended to central-western and southeastern Brazil. P. conata can be easily separated from all other species of the genus by the distinct conical projection of pronotum ( Fig. 15 A). It shares some characters with P. bipunctata sp. nov. ( Fig. 5 ), like a pair of white maculae on anterior lobe of pronotum; small black denticles on fore and hind tibiae; absence of tubercles between meso- and metasternum; connexives with silvery setae; apical macula of forewings with similar shape; and transverse areas without setae on abdominal sternites. However, both are easily distinguished by the presence of a conical process on the pronotum of P. conata , absent in P. bipunctata sp. nov.
