Etymology. The name fuscomarginatus refers to the brown (fuscus lat. = brown) outer margin of the anal area of the alae of this new species.

Differentiation. Very similar to P. multilineatus ( Rehn, 1904) from Costa Rica and Panama but differing by the yellowish-orange abdominal terga, the bright green and apically black femora in both sexes, the more slender cerci in the ♂♂ and the slightly shorter subgenital plate in the ♀♀. Also very similar to P. rosanti n. sp., but easily distinguished by the bicoloured anal fan of the alae and the uniformly black tibiae (green apically in rosanti n. sp.).

Description. ♀ ( Fig. 11 ). Very colourful insect of average size and body shape for the genus. Length of body 61.5 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 longitudinal lines. Head greenish yellow to orange with many distinct broad longitudinal black lines. Antennae including scapus and pedicellus uniformly black. Eyes dark beige to brown. Pro- and mesonotum dark yellow to greenish yellow or even bright orange, covered with tiny blunt yellow granules and laterally framed with a distinct broad longitudinal black band on each side. 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 brownish translucent with a large, oval yellowish translucent field at the base. Abdomen bright orange to greenish yellow. Terga VIII–X with black speckles or mottling. Cerci cylindrical and slender, pointed towards apex, about as long as anal segment, black. Subgenital plate flat and at best spoon-shaped, posterior margin rounded, at best reaching to centre of anal segment; drab orange to brown. All femora greenish yellow to orange with black knees, tibiae entirely black; basitarsi and second tarsomeres black, remaining tarsomeres yellow to orange.

Measurements PT [mm]: Body 61.5, pronotum 3.5, mesonotum 5.5, metanotum 9.3, median segment 3.1, tegmina 7.0, alae 42.5, profemora 12.4, mesofemora 11.3, metafemora 15.0, antennae> 44.5.

♂ ( Fig. 12 ). Length of body 45.0–46.0 mm. Similar to ♀, but more slender and elongate. Poculum large and bulgy, tapering towards pointed apex, at least reaching to posterior margin of anal segment; brown to beige. Tergum IX and anal segment bearing large black speckles near the lateral margins. Anal segment globose with the lateral surfaces projecting almost hemispherical. 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 spines near the base on the inner side of each cercus.

Measurements HT [mm]: Body 46.0, pronotum 2.5, mesonotum 4.5, metanotum 3.9, median segment 3.6, tegmina 4.0, alae 32.2, profemora 12.6, mesofemora 9.0, metafemora 12.4, antennae 55.0.

Measurements PT [mm]: Body 45.0, pronotum 2.4, mesonotum 3.8, metanotum 5.6, median segment 2.1, tegmina 4.5, alae 31.5, profemora 12.5, mesofemora 9.9, metafemora 13.0, antennae> 58.0.

Distribution. French Guiana: Commune de Roura, Montagne des Chevaux [coll. OC], Commune de Maripasoula, Mitaraka [coll. OC]; Roura, Piste Coralie [MNHN].
