Madagascar ( Granger 1949).

Description.

Female. Fore wing length 2.5 mm. Head. Width of head (dorsal view) 1.9 × its median length. Transverse diameter of eye (dorsal view) 2.0 × length of temple. OOL 2.2 × Od; POL 1.3 × Od; OOL 1.7 × POL. Longitudinal diameter of eye (lateral view) 1.4 × its transverse diameter. Face medially not convex, with weak medio-longitudinal carina, 1.6 × as wide as high. Longitudinal diameter of eye 3.6 × length of malar space (anterior view). Malar space 0.7 × base of mandible. Malar suture weakly impressed. Width of hypoclypeal depression 1.3 × larger than distance from depression to eye. Antenna with 22 antennomeres, 0.9 × as long as fore wing. First, middle and penultimate flagellomeres 2.5 ×, 2.1 ×, and 2.0 × as long as wide, respectively. Mesosoma 1.6 × as long as high. Mesoscutum setose on notaulic area and posteriorly, anteromedially widely glabrous. Propodeum with branching medio-longitudinal keel in apical third and without medio-longitudinal impression. Wings. Vein r arising from basal 0.45 × of pterostigma. Vein 1-R1 1.6 × as long as pterostigma. Marginal cell 8.5 × longer than distance from its apex to apex of wing. Vein 3-SR 2.4 × vein r, 0.5 × vein SR1, 1.4 × vein 2-SR. Vein 2-SR+M 0.45 × vein 2-SR, 1.0 × vein m-cu. Vein cu-a weakly postfurcal. Legs. Hind femur 4.0 × longer than wide. Fifth segment of hind tarsus 0.95 × as long as second segment, 0.47 × as long as hind basitarsus. Claws with large, protruding and blunt basal lobes. Metasoma. Median length of T1 0.8 × its apical width; margin of its median area crenulate. T1 without dorsal carinae and sublateral posteriorly converging carinae; dorsolateral carinae of T1 developed. T2 medially 1.2 × as long as T3; basal width of T2 1.6 × its median length. Anterolateral areas of T2 round, strongly separated by incomplete crenulate furrows, complete sharp crenulate margin delineating not elevated subparallel-sided median area, and S-shaped sublateral converging carinae. Dorsolateral impressions of T2 deep, S-shaped, and crenulated; spiracle located in middle of T2, near its lateral margin. Suture between T2 and T3 deep, curved, and crenulate. Apical margins of T3-T6 without transverse subapical grooves. Ovipositor sheath 0.7 × as long as hind tibia and 0.22 × as long as fore wing. Sculpture and colouration. T2-T4 granulate-rugulose to granulate. Coloration pattern similar to S. somnialis and S. suavis. Tegulae yellowish brown; pterostigma brown; wing veins pale brown; wing membrane weakly darkened.

Male. Unknown.
