D e s c r i p t i o n: ♀: Body length 13.5-14 mm. Flagellum stout and filiform, with 40 flagellomeres; all flagellomeres (except distal one) wider than long; 1 st flagellomere 1.1x wider than long; preapical flagellomere 1.2x wider than long. Head with long and scattered erected pale hairs. Temple moderately and roundly narrowed behind eye, dorsally 0.65x as long as eye. Distance of lateral ocellus to eye 1.0x ocellar diameter. Frons coarsely rugose-punctate. Face with coarse rather dense punctures. Clypeus almost flat, 2.25x wider than long, with rather dense punctures and sharp rounded apical margin. Gena 1.5x wider than eye, with scattered punctures ventrally. Mandible large and moderately swollen centrally, with two teeth, lower tooth small and not bent inwards. Malar space 0.4-0.5x as long as width of mandibular base. Genal carina reaching hypostomal carina far from mandibular base, hypostomal carina slightly elevated.

Mesosoma covered with pale hairs. Pronotum with elongate collare and swollen upper margin, sides with scattered punctures and some striae at caudal margin. Epomia short. Notaulus not impressed. Mesoscutum smooth and shining, with denser punctures in frontal half and scattered punctures caudally. Mesopleuron with scattered coarse punctures, coarsely striate in ventral half. Epicnemial carina narrow, reaching subtegular ridge. Metapleuron coarsely punctate-striate; juxtacoxal carina present. Scutellum almost flat, 1.2x wider than long, with scattered fine puncture, without lateral carina. Propodeum long. Area basalis not carinate and without median tubercle. Area superomedia almost rectangular, with rounded frontal side, rugose, 2.0x longer than wide. Costula not indicated. Area petiolaris rugose, with lateral carina. Legs stout. Fore and mid tibia with numerous external spurs. Hind coxa smooth and shining, with scattered punctures, without scopa. Hind femur stout, finely granulate and with scattered setiferous punctures, 3.0-3.3x 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 distal to the middle. Nervulus postfurcal (2x width).

Metasoma amblypygous, hypopygium long, but not reaching metasomal apex. Postpetiole widened apically, without distinct dorsal carina; median field not separated, partly with fine aciculation and punctures, lateral field with fine scattered punctures. Gastrocoelus small and slightly impressed, 2x longer than wide, smooth; thyridium not impressed. 2 nd tergite about as long as wide, with fine scattered punctures, 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: Largely red. Antenna tricoloured: Scape, pedicle and flagellomeres 1-7 red, flagellomeres 8-16 yellowish, following flagellomeres black. Head red; palps yellow-red; frontal orbit or entire inner orbit up to vertex and sometimes spot on malar space yellow. Mesosoma red; black are propleuron, side of pronotum centrally, wide margins of mesopleuron and metapleuron, complete mesosternum, scuto-scutellar groove, area beside scutellum, basomedial spot and apical margin of propodeum. Yellow are collare and wide upper margin of pronotum, central spot of mesoscutum (in one specimen paramedi- an stripes on mesoscutum confluent apically), sometimes subtegular ridge, complete scutellum and postscutellum. Metasoma red; basal bands or transversal stripes of 2 nd to 6 th tergites black; 7 th tergite with median yellow spot; in one specimen central spot on postpetiolus and apical stripes of 2 nd to 6 th tergites yellowish. Legs red; trochanters and basoventral spots on all femora black; yellow are subbasal rings of all tibiae and mid and hind tarsomeres except brownish tips. Wings slightly yellowish infuscate, pterostigma yellow.
