Fig. 12 View Fig


Large species; face yellowish-orange; general coloration yellowish-orange with some median dark spots on metasomal tergites; face densely punctate, clypeus slightly transverse and smooth; mesonotum densely punctate; area superomedia about 2.5 x longer than wide, laterally hardly delimited; tergite 1 smooth, tergite 2 hardly sculptured; female femoral tooth small; ovipositor long, apically sinuate; POL 0.6; OOL 1.0; CT 1.6; ML 0.8; OT 1.7–1.9; FFT 1.

Differential diagnosis

Species closely related to P. roberti   , characterized by the dense punctation of face, the propodeum with area superomedia hardly delimited laterally and the almost smooth second metasomal tergite.

Type material


MADAGASCAR: ♀ ( MNHN EY3501), Ampandradava, 23°50’ S, 44°52’ E, verbatim label data: “Madagascar, Bekily [Ampandrandava], reg. sud de l’île, XII.33 ”, complete.



MADAGASCAR: 3 ♀♀, 2 ♂♂ ( MNHN EY3502–3506), same locality, Dec. 1930, Jan., Mar. and Dec. 1933.



LENGTH. 5.9, 6.9 (5.9–7.5) (4 specimens).

HEAD. Strongly constricted behind eyes. Vertex and temple finely granulate. Ocellar triangle equilateral. Frons laterally punctate-granulate, centrally smooth, mid-longitudinally bulging. Face midlongitudinally bulging, punctate, punctures sparser centrally and along inner orbits. Clypeus shining,

almost unpunctate, slightly transverse. Mandible stout and curved. Malar line moderately long. Antenna with 37–38 flagellomeres.

MESOSOMA. Slightly elongate, about 1.7 x longer than high. Pronotum smooth. Mesonotum shining, densely punctate. Mesopleuron shining, more sparsely punctate, speculum smooth. Scutellum almost smooth. Propodeum densely punctate, area basalis truncate, area superomedia about 2.5 longer than wide, laterally hardly delimited. Legs: femoral tooth present but small.

METASOMA. Shining. Tergite 1 almost smooth. Tergite 2 with shallow aciculation and sparse punctures. Following tergites alutaceous. Tergite 2 about 2.5 x longer than apically wide. Ovipositor moderately long, its apical third slightly sinuate.

COLOR. Yellowish-orange overall with some median dark spots on metasomal tergites, flagellum and metasoma infuscate. Wings hyaline, pterostigma orange.


Length: 6.5 (6.3–6.7) (2 specimens). Ocellar triangle large, oculo-ocellar distance (OOL = 0.4) shorter than inter-ocellar distance (POL = 0.6). Hind femur stouter, femoral tooth stout followed by a row of rather strong tubercles. Otherwise similar to female.
