Etymology: Named after Thibault Rosant ( French Guiana), who found this species in French Guiana.

Differentiation. Very similar to P. multilineatus ( Rehn, 1904) from Costa Rica and Panama and P. fuscomarginatus n. sp. from French Guiana. It differs from P. multilineatus by the yellowish-orange abdominal terga, scapus and pedicellus, the bright yellow and apically black femora in both sexes and the considerably more slender, black cerci in the ♂♂. From P. fuscomarginatus n. sp. it differs by the uniformly coloured anal fan of the alae and the bicoloured tibiae in both sexes.

Description. ♀ ( Fig. 9 ). Very colourful insect of typical size and body shape for the genus. Length of body 49.8 mm. Body surface smooth, except for some tiny blunt granules on pro- and mesonotum. General colour of body bright orange to greenish yellow with several black lines. Head yellow with several fine longitudinal black lines, sometimes distinct, sometimes interrupted. Antennae uniformly black, except scapus and pedicellus being drab yellow. Eyes marbled yellow and black. Pro- and mesonotum yellow to greenish yellow or even bright orange, covered with tiny blunt yellow granules and laterally bordered by a distinct longitudinal black band. Tegmina at best reaching posterior margin of metanotum, dark brown to black with greenish yellow veins and a bright orange band along the radial vein. Costal area of alae yellow to greenish yellow with several distinct or indistinct black to brown longitudinal lines. Anal area of alae translucent. Abdomen bright orange to greenish yellow with a fine green line at the lateral margins of the terga. Terga VIII–X with black speckles or mottling. Cerci cylindrical and slender, pointed towards apex, about as long as anal segment, black. Subgenital plate spoon-shaped, posterior margin rounded, at best reaching to posterior margin of anal segment; yellow to greenish orange. Legs very colourful, all femora greenish yellow to orange with black knees, tibiae black with apical quarter yellow; basitarsi and second tarsomeres black, remaining tarsomeres yellow to orange.

Measurements HT [mm]: Body 49.8–53.1, pronotum 2.9–3.0, mesonotum 4.5–5.3, metanotum 5.5–7.6, median segment 2.4–2.7, tegmina 5.9–6.5, alae 35.5–38.9, profemora 10.6–10.7, mesofemora 9.3–10.0, metafemora 12.4–12.7, antennae> 30.0.

♂ ( Fig. 10 ). Similar to ♀, but more slender and elongate. Poculum large and bulgy, tapering towards pointed apex, at least reaching to posterior margin of anal segment, bright yellow. Tergum IX and anal segment with large black speckles near the lateral margins. Anal segment globose with the lateral surfaces projecting almost hemispherically. Cerci large, slender and curved inwards and downwards with rounded apex, slightly swollen in apical half, at least 1.5x longer than anal segment, with two sub-basal spines on the inner surface of each cercus.

Measurements PT [mm]: Body 36.9, pronotum 2.3, mesonotum 3.4, metanotum & median segment 4.8, tegmina 3.5, alae 25.7, profemora 10.8, mesofemora 8.3, metafemora 11.1, antennae 48.7.

Comments. The HT specimen was collected by the French G.E.P. team on their first expedition to French Guiana. Unfortunately, no locality was given on the label but it has certainly been collected in Kaw Mountain . The authors have not been able to obtain detailed measurements of the PT specimens (♂ and ♀) in MZUSP, hence no measurements are given for these specimens .

Distribution. So far recorded from St. Laurent du Maroni and Montagne des Chevaux in French Guiana [TR] and Trairão in the State of Pará, Brazil [MZUSP].
