Diagnosis. Blackish species, easily distinguished by the pyriform metasoma, strongly petiolate and with only two apparent tergites.

Description. FEMALE: B: 1.5; F: 1.5; O: 0.1.

Head. Head subcubic in dorsal view. Face, clypeus, mouthparts and antenna with sparse pilosity. Occipital carina widely absent dorsally, joining ventrally hypostomal carina before mandibles. Antenna with 14 flagellomeres. Frons and vertex smooth and shining with some punctures. Temples long, subparallel then abruptly rounded, head not constricted behind eyes. Face transverse, nearly twice wider than high, shining, sparsely punctate. Clypeus as wide as face, apical margin acute and regularly rounded. Subocular sulcus deep. Malar line a little shorter than mandibular basal width. Mandible long, moderately wide, upper tooth twice as long as lower tooth.

Mesosoma. Pronotum transversally wrinkled. Mesopleuron almost smooth with some rugosities below tegula, sternaulus anteriorly wide, rugose. Metapleuron finely reticulate. Mesoscutum smooth and shining, notaulus absent, scuto-scutellar groove deep with a median transverse carina. Propodeum rugose without any carina. Forewing with most of venation absent: only A, 1cu-a and M tubular and pigmented, last abscissa of Rs almost unpigmented but a short central segment. Forewing with short pilosity but basally glabrous.

Metasoma. Tergite I tubular, half as wide as propodeum, as wide apically than basally, with longitudinal striations, ventral margins separated and subparallel. Tergite II+III smooth, dorsal suture absent, the following tergites concealed. Ovipositor very short, sheath hardly protruding.
