Diagnosis.

Easily separated from the congeners by the following set of characters: (i) median carina forming a low elongated crest which extends from between the prozonal carinae to the base of hind legs; (ii) vertex a little less than two eyes wide; (iii) brown body without distinct patterns; (iv) rounded pulvilli of hind tarsi; (v) female subgenital plate oval with moderately protruding triangular apex; (vi) alae dark brown with venation of the same color. Differs from P. maroon by characters iii, iv, v, and vi.

Description.

Macropronotal. In anterior view, top of vertex approximately at level of upper margin of eyes. Vertex a little less than two eyes wide. Frontal costa bifurcation in upper third of eye height. Facial carinae forming long oval shape. Paired ocelli approximately at half of eye height. Midline of antennal groove at level of bottom margin of eyes. Antennae composed of 13 visible segments; apical six flattened, last segment white. In dorsal view, vertex of isosceles trapezoidal shape. Medial carina visible in anterior half of vertex. Lateral carinae in form of small tubercles. Prozonal carinae as long as eye as seen in dorsal view, strongly convergent caudad. Median carina visible throughout length of pronotum, forming low but long crest in lateral view (extending from between prozonal carinae to base of hind legs). Pronotal surface covered in small tubercles and carinulae. Humeral angles wide and blunt. Lateral lobes rectangular, projected laterally, with thin white border. Tegmina large and oval. Alae reaching pronotal apex; dark brown with dark brown venation. Anterior and middle femora long and smooth. Anterior and middle femora long and smooth. Anterior and middle tarsi with long first segment and extremely long second segment. Hind femur robust, with two tubercles on dorsal margin; moderately sized sharp antegenicular tooth, genicular tooth barely visible. Hind tibia thin, serrated along caudal margin. Hind tarsus long; first segment extremely long, with three elongated pulvilli; third segment missing in the holotype. Ovipositor extremely elongated, serrated. Base of subgenital plate with triangular notch; shallow stitch line extending from it throughout most of the length of the plate. Subgenital plate elongated with moderately protruding triangular apex.
