Diagnosis

Moderately large species; face black; head white and black, mesosoma rufo-testaceous with black markings, metasoma orange brown, tergite 2 and apex of tergite 1 black, following tergites dorsally brown; face moderately punctate-granulate, clypeus transverse and smooth; mesoscutum densely punctate-granulate, apically smoother, scutellum almost smooth; area superomedia about 2 x longer than wide; female femoral tooth absent; forewing with 2rs-m 4 x shorter than the section of M separating 2rs-m and 2m-cu; ovipositor long, apically sinuate; POL 1.0; OOL 1.3; CT 1.8; ML 0.6; OT 2.2; FFT 0.

Differential diagnosis

Species superficially close to P. caris  and related species with white face, distinguishable by the dark color pattern, the longer ovipositor and the very short vein 2rs–m.

Etymology

Euphonic reference to the collection place.

Description

Female

LENGTH. 4.9.

HEAD. Strongly constricted behind eyes. Temple very short, finely granulate. Vertex granulate. Ocellar triangle almost equilateral. Frons granulate. Face moderately punctate-granulate (punctures sparser laterally), slightly bulging mid-longitudinally. Clypeus almost unpunctate, slightly transverse. Malar line rather short. Mandible short and stout. Face, clypeus, mandible and vertex with sparse white pilosity. Antenna with 31 flagellomeres.

MESOSOMA. Moderately elongate, 1.8 x longer than high. Mesoscutum and pleurae densely punctategranulate anteriorly, smoother posteriorly. Pronotum almost smooth centrally, epomia distinct. Scutellum smooth with some punctures. Speculum almost smooth. Propodeum shining, densely punctate. Area basalis opposite, area superomedia 2 x as long as wide. Propodeum, pleurae and ventral margin of coxae covered with white hairs. Wings: fore wing with vein 2rs–m very short, about 0.3 x as long as 2m–cu, and basal to 2m–cu by 4 x its length. Legs: long and thin, without a distinct tooth on hind femur.

METASOMA. Post-petiole, tergite 2 and base of tergite finely aciculate.Tergite 1 slightly longer than tergite 2. Tergite 2 about 3 x longer than apically wide. Post-petiole almost flat. Glymma long. Ovipositor long and thin, its apex strongly sinuate.

COLOR. Head ivory white with black markings. Black: antennae, center of face and frons, vertex, occiput, posterior half of outer orbit and a dorsal spot crossing the orbit. Mesosoma rufo-testaceous with black marking on median lobe of mesoscutum, scuto-scutellar groove, lateral sides of scutellum, post-scutellum and dorsal face of propodeum. Metasoma orange brown. Tergite 1 basally and laterally yellow. Postpetiole and tergite 2 black, the following tergites dorsally brown. Fore and mid legs pale brown with femora slightly darker. Hind legs blackish-brown, tibia slightly paler. Wings hyaline, pterostigma dark brown. Ovipositor sheath dark brown.
