D e s c r i p t i o n: ♀: Body length 13 mm. Length of fore wing 9 mm and of ovipositor 14 mm. Antenna with 48 flagellomeres; 1 st flagellomere 5.5× longer than wide and 0.66× as long as eye; preapical flagellomere about square. Temple very short, strongly and roundly narrowed behind eye, dorsally 0.2× as long as eye. OED 1.0× and OOD 1.4× ocellar diameter. Vertex and frons coarsely and densely punctate. Frons strongly and concavely impressed medially. Face densely but finely punctate. Clypeus 2.0× wider than long, with scattered punctures, apical margin rounded. MI 0.5. Mandible with strong baso-ventral lamella.
Mesosoma very coarsely and densely punctate, 1.53× longer than high. Fronto-ventral edge of pronotum strongly curved. Side of pronotum densely punctate, pronotal groove partly smooth. Epicnemial carina low, pleural part present, transversal part absent. Apical transverse carina of propodeum shortly present laterally, widely absent medially. Hind femur 5.9× longer than wide. Hind metatarsus 0.75× as long as hind femur. 2 nd hind tarsomere 1.53× as long as 3 rd one. Hind claw with short teeth, strongly bent apically.
Areolet with long stalk (stalk as long as areolet); vein 2m-cu reaching areolet in its distal 0.8. Vein 1cu-a slightly postfurcal by 1× its width. Postnervulus intercepted in middle. Nervellus of hind wing slightly reclivous, intercepted in its apical 0.75.
Metasoma slender, tergites with narrow spiracles, spiracles not bulged. 1 st tergite 2.35× longer than wide, with rather dense and coarse lateral punctures. 2 nd tergite 1.8× longer than wide, with dense but fine punctures, ± shining. 3 rd tergite 1.4× as long as wide, with dense fine punctures. Ovipositor 1.55× longer than fore wing, 1.7× longer than metasoma and 3.6× longer than hind tibia.
Color: Black. Flagellum black, dark redddish-brown in apical half. Palps, mandible except teeth, clypeus, wide complete orbits, malar space and paramedian spots on face yellow. Mesosoma black, with yellow color pattern: frontal and upper margins of pronotum, spots on tegula and on subtegular ridge, hook-shaped antero-lateral spot on mesoscutum (confluent apico-medially), wide stripe on mesopleuron, spot on mesosternum, upper division and central spot on metapleuron, sides and apex of scutellum, postscutellum, wide triangular median spot and lateral spots on propodeum yellow. 1 st to 3 rd tergite black, 2 nd and 3 rd tergites with central red spots; following tergites and hypopygium reddish. 1 st tergite with basolateral yellow spot; 1 st to 3 rd tergite with apical yellow bands. Fore and mid coxae and trochanters yellow frontally, blackish caudally; hind coxa with ventral and dorsal yellow spots; all trochantelli yellow; femora tibiae and fore tarsus reddish, femora and tibiae with ± distinct dorsal brownish stripes; mid and hind tarsi brown. Wings with brown apical stripes; pterostigma brown.
♁ unknown.
R e m a r k: This new species belongs to the villosus group sensu CHANDRA & GUPTA (1977) and runs to S. baluchistanensis (CAMERON, 1906) in their key. It differs by the less extended yellow color pattern of meso- and metasoma.
