Diagnosis. -

P. carli is characterized by the long and moderately wide fore wings; the longest ventral spines of the fore tibia are more than twice as long as the diameter of the tibia. The genicular area of all legs is usually whitish, rarely slightly infumate. The paraproctal outgrowths have the apical area suddenly upcurved, are roughly triangular with the obtuse tip faintly curved posteriorly, and carrying along dorsal margin a fine, compressed, stiffened lamella. The female subgenital plate has the elongate triangular basal area with substraight to slightly concave lateral margins. The narrow apical area is only slightly shorter than the basal area, about three quarters of the basal area.

Description. -

Large species; habitus as genus. Prosternal lobes compressed triangular, at beginning of narrow conical apical area slightly constricted, tip subacute to subobtuse; mesosternal lobes in basal area wide, afterwards elongate conical to nearly cylindrical with subtruncate tip; metasternal lobes compressed, with concave internal and strongly convex external margins; gradually passing over into conical (nearly sub-cylindrical) apical area with obtuse tip (Fig. 2J View Fig. 2 ).

Wings distinctly surpassing hind knees (Fig. 1A View Fig. 1 ). Fore wings 2.3-2.8 × longer than wide. Venation: radius with radius sector arising in about mid-length of tegmen; media free, two-branched, branching behind basal third; cubitus anterior three-branched (CuA + CuPaα + CuPaβ after Béthoux 2012), branching in basal third and before mid-length; cubitus posterior (CuPb) undivided; with five anal veins, the last one incomplete. Hind wings cycloid, about 1.8-2.2 × wider than long.

Legs. Fore coxa with a strong spine at swollen anterior surface; and mid-coxa with a smaller spine at external (= anterior) margin. Fore femur with 3-5 small spines at anterior-ventral margin; mid femur with 3-5 spines at anterior-ventral and 6 smaller spines at posterior-ventral margin. Hind femora with 5-7 external and 4-5 internal small spines on ventral margins; hind tibiae with dorsal spines on inner margin larger than on outer margin, ventral margins with few minute spinules; on both sides with 4 apical spurs, the dorsal two pairs very large, the following pair medium, the ventral-most pair small; internal spurs larger than external counterparts; ventral margin with 2-4 external and 0-1 internal spinules.

Male. Paraproctal outgrowths long, roughly cylindrical with rugose and setose surface, apex obtuse with beaked extension with subobtuse tip that carries a fine, stiff lamella on top (Fig. 3A-D View Fig. 3 ). Subgenital plate with lateral margins upcurved in basal area; ventral surface behind basal third with obtuse lateral carinae, nearly parallel in about apical third and little projecting behind apical margin; apical margin concave, on both sides with a substraight stylus (Fig. 2A View Fig. 2 ). Phallus membranous (Fig. 7A-F View Fig. 7 ).

Female. Subgenital plate acute-angled triangular in more than basal half, terminating into a long apical spine with regularly converging margins to acute tip; at transition between basal and apical areas sometimes slightly sloped (Fig. 5A-C View Fig. 5 ).

Coloration. -

Largely black or dark brown with fine and irregular light spots; pronotum reddish-brown or marbled with dark and light flecks; legs largely black with light, often white genicular areas, dorsal surface of fore and mid tibiae of lighter color; posterior half of hind femora and hind tibiae ochre. Face dark brown to black, marbled with numerous small lighter spots, in some specimens also with larger medium to dark brown areas; extension of light and dark areas variable. Tegmen semi-transparent, brown or blackish-brown with larger dark spots between subcosta and cubitus and smaller dark spots in anal area; in anterior area of lighter color. Hind wings semi-transparent with a trace of grey, in anterior area often brownish.
