Description. Body length: 5.0–6.1 mm. Head black; frons, clypeus and base of mandibles light brown to testaceous, slightly translucent; apex of mandibles light brown; palpi dark brown. Antennae black; antennomeres X–XI yellowish-brown, except at base of X and tip XI. Pronotum orange-yellow with wide medial black patch stretching longitudinally from anterior to posterior margins. Elytra, thorax, legs and abdomen dark brown.
Male (Fig. 6). Head as long as wide, broadly rounded behind eyes, densely pubescent; occipital region and frons convex; clypeus wide, emarginated anteriorly. Eyes rounded, slightly prominent. Maxillary palpi elongate, last palpomere slender and slightly securiform.Antennae (Fig. 12) long, serrate and slightly compressed dorso-ventrally; dorsal surface of antennomeres VI–IX with irregular longitudinal line, not straight, varying in length and width. Pronotum densely pubescent, transverse, 1.6 times wider than long; lateral margins almost parallel, explanate upwards and shortly notched before basal angles. Elytra finely rugous, densely covered with erect brownish setae; each elytron 5 times longer than wide. Legs slender; tarsomeres increasing in size from pro- to metathoracic legs; inner claw of prothoracic tarsus broadly lamellate at base, meso- and metathoracic tarsal claws with sharp protruding tooth. Last abdominal ventrite (Fig. 32) bilobed and slightly acute at apex; abdominal tergite VIII (Figs 32–34) short and broad, strongly constricted posteriorly, forming broad and short apical projection bearing two contiguous glandular openings at apex. Aedeagus (Figs 56–58): ventral wall of tegmen long and broad, lateral sides emarginated, apical margin truncate with short median incision, sparse short setae along lateral and apical margins; parameres very short, hidden behind dorsal margins of tegmen, bearing a few thin apical setae; median lobe long and slender, membranous apically; internal sac hidden inside median lobe, except apex of sclerites; ventral sclerite entire, not divided, apex slightly acute, curved ventro-laterally; dorsal sclerites slender, with apex curved dorso-laterally.
Female. Similar to male but antennae lacking longitudinal lines; pronotum not notched laterally; tarsal claws simple; abdominal ventrite VII (Fig. 40) 2.7 times wider than long, not divided, lateral margins arched, distal margin with short and broad projecting tip; abdominal tergite VIII broad and simple.
Differential diagnosis. Colour pattern similar to P. gurupi sp. nov. and P. monoceros sp. nov. Antennal lines from antennomeres VI–IX; last abdominal ventrites of males bilobed, with acute apex; last abdominal tergite of males strongly constricted posteriorly forming broad and short apical projection.
Distribution. The species was known only from the type series from French Guiana (CONSTANTIN 2010b). It is recorded for the first time from the State of Amapá in Brazil (Figs 59–60).
