Diagnosis. -

In general characters, P. carnarius differs from all other species of the genus that I have studied by the wide fore wings, the dark colored hind wings, and by the very long and distinctly curved ventral spines of the fore tibia; the longest of these spines are more than three times (3.3 ×) longer than the width of the tibia while in the other species the longest spines are more than two times longer than the tibia width but shorter than three times (2.2-2.8 ×) and are only slightly curved or substraight. In sex-specific characters, males differ from other species by the paraproctal outgrowths that have the pre-apical area bulging ventrally and then are gradually narrowed to the tip that carries a small stiffened obtuse pad. Females have the subgenital plate wide at base with rather strongly narrowing, substraight lateral margins, and the narrow apical area short, about half the length of the wide anterior area.

Description. -

Large species; habitus as genus. Prosternal lobes near base compressed, afterwards long spiniform, thin; mesosternal lobes in basal area moderately wide, about between basal half and basal two thirds compressed, afterwards tubular with obtuse or subtruncate tip; metasternal lobes compressed triangular with faintly concave internal and strongly convex external margins, towards tip swollen conical with obtuse tip; without narrow cylindrical apical area (Fig. 2N View Fig. 2 ).

Wings distinctly surpassing hind knees (Fig. 1J View Fig. 1 ). Fore wings 2.0-2.23 × longer than wide. Venation: radius with radius sector arising behind mid-length of tegmen; media two-branched, branching behind basal third; cubitus anterior three-branched, branching in basal third and behind mid-length; cubitus posterior undivided, at base running very close to first analis; with 5-6 anal veins, the last one incomplete; the first and second anal veins with a short common base; the second vein branching again into 2 veins in subbasal area (thus 6-7 anal veins). Hind wings nearly semicircular, only slightly wider than long (about 1.3 ×).

Legs. Fore coxa with a strong spine at swollen anterior surface; mid coxa with a smaller spine at anterior margin. Fore femur with 5-6 small spines and mid femur with 3-5 spines at anterior-ventral margins, mid femur also with 3-6 posterior-ventral spines. Hind femur with 4-7 external and 2-3 internal small spines on ventral margins; hind tibia with dorsal spines on inner margin slightly 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 corresponding external counterparts; ventral margin with 3 external and 1 internal spinules.

Male. Paraproctal outgrowths elongate, in subapical area slightly but distinctly widening, somewhat curved dorsad and with converging margins towards subacute tip; at tip provided with a tiny, compressed, obtuse pad (Fig. 4E-G View Fig. 4 ). Subgenital plate in about basal half slightly swollen with convex and approaching lateral margins [in Fig. 2E View Fig. 2 , barely expressed from freshly molted specimen with still soft cuticula when captured]; in apical half with subparallel or faintly diverging lateral margins which towards tip form rounded lateral carinae, at tip with insertion of stylus; otherwise apical area compressed with apical margin subtruncate, interrupted by a deep incision with rounded bottom. Phallus membranous (Fig. 7O-P View Fig. 7 ).

Female. Subgenital plate wide at base, triangularly narrowing posteriorly and terminating into a short spiniform apical area; basal area nearly twice as long as apical area, faintly sloping in transition zone between both areas (Fig. 5J View Fig. 5 ). In a female from BaVi the baso-lateral areas are curved dorsad, giving the impression of a narrower plate, and the transition zone more strongly expressed (Fig. 5K View Fig. 5 ).

Coloration. -

General color light brown, mixed with dark pattern; pronotum light brown to ochre, with or without some darker elements; legs spotted with light and darker flecks. Head: face yellowish-brown with dark spots; clypeus and labrum brown, mouthparts of same color; below median ocellus and at clypeo-frontal suture with black spots, in some individuals also clypeus darkened; antennae in basal area black with white annulation, behind about basal quarter gradually getting lighter towards tip. Tegmen light, semi-transparent with dark brown or nearly black spots; hind wings bright medium to dark brown, along margin transparent, in anterior area semi-transparent with some dark spots along margin; in anterior area of the dark field with few scattered whitish, transparent spots.

(2 males, 3 females). In mm. Body w/wings: male 60-63, female 58-62; body w/o wings: male 36-37, female 38-40; pronotum: male 9.5-10.3, female 10.0-10.5; tegmen: male 45-46, female 44-49; tegmen width: male 21-23, female 20-22; hind femur: male 27-30, female 29-32; antenna: male 90, female 100; ovipositor: female 29-31.
