D e s c r i p t i o n: ♀: Body length 14 mm. Flagellum stout and filiform, with 38 flagellomeres; 1 st flagellomere about as long as wide, following flagellomeres (except the distal one) wider than long, preapical flagellomere 1.1x wider than long. Head with long and scattered erected pale hairs. Temple long, moderately and roundly narrowed behind eye, dorsally 0.75x as long as eye. Distance of lateral ocellus to eye 1.3x ocellar diameter. Stemmaticum densely punctate; frons with scattered punctures, frontal orbits almost smooth. Face moderately bulging centrally, with coarse scattered punctures. Clypeus almost flat, 2.2x wider than long, with scattered punctures and sharp rounded apical margin. Gena about as wide as eye, smooth, with very scattered punctures ventrally. Mandible large and stout, with two teeth; lower tooth very small and slightly bent inwards. Malar space 0.4x as long as width of mandibular base. Genal carina reaching hypostomal carina far from mandibular base, both carinae low.

Mesosoma with erected pale hairs. Pronotum with elongate collare and swollen upper margins, side of pronotum smooth, with scattered punctures. Epomia short. Notaulus not impressed. Mesoscutum smooth and shining, with denser punctures in frontal half and scattered punctures caudally. Mesopleuron with scattered coarse punctures. Epicnemial carina narrow, reaching subtegular ridge. Metapleuron with dense coarse punctures; juxtacoxal carina present. Scutellum almost flat, about as long as wide, with scattered fine punctures, without lateral carina. Propodeum long. Area basalis not carinate and without median tubercle. Area superomedia almost rectangular, with rounded frontal side, rugose, 1.5x longer than wide. Costula not indicated. Area petiolaris rugose, with lateral carina. Legs stout. Fore and mid tibiae with numerous external spurs. Hind coxa smooth and shining, with scattered punctures apically, without scopa. Hind femur stout, finely granulate and with scattered setiferous punctures, 3.2x longer than wide. Distal hind tarsomere long and moderately curved, about as long as 2 nd hind tarsomere. Claws strong, not pectinate, distinctly bent apically (by 90°).

Areolet wider than long, pentagonal, frontal distance of intercubiti c. 5x their width; 2 nd recurrent vein reaching areolet widely distal of the middle. Nervulus postfurcal (2x its width).

Metasoma amblypygous, hypopygium long, but not reaching metasomal apex. Postpetiolus widened apically, without distinct dorsal carina; median field not separated, with fine aciculation and some fine punctures, lateral field with fine scattered punctures. Gastrocoelus small and slightly impressed, 2x longer than wide and with some fine longitudinal ridges; thyridium not impressed. 2 nd tergite 1.2x longer than wide, with fine rather dense punctures, smooth and shining. Following tergites with fine scattered punctures, shining. 2 nd and 3 rd sternites with median folds. Ovipositor sheath slightly extending behind metasomal apex.

Colour: Black with rich yellow colouration. Yellow are stripes on flagellomeres 9-14, palps partly, clypeus (except black apex and sides), face, wide frontal orbit up to occipital carina, gena, propleuron, collare and wide upper margin of pronotum, large central spots on mesoscutum, mesopleuron and metapleuron, spot on tegula, subtegular ridge, praescutellar carina, scutellum, spot on postscutellum, area dentipara of propodeum, basal half of 2 nd tergite, large lateral spots on 3 rd to 7 th tergites, small median spot on 7 th tergite, sides of 2 nd to 6 th sternites, all coxae except black bases, basal rings on fore and mid tibiae and subbasal ring on hind tibia, basal rings on tarsomeres except black distal tarsomeres. Wings hyaline; pterostigma brown, yellowish at proximal margin.
