Holotype: ♀ " Nepal, Prov. Mahakali, Distr. Darchula, Bachtal S Thaisan, 29°51´12´´N 80°40´17´´E, 2017-06-08, A. Kopetz " (Erfurt).
D e s c r i p t i o n: ♀: Body length 14 mm. Flagellum filiform, with 41 flagellomeres; 1 st flagellomere 2.3x longer than wide, c. 12 th flagellomere square, widest flagellomeres c. 1.1x wider than long, preapical flagellomere square. Temple strongly and almost linearly narrowed behind eye, dorsally 0.35x as long as eye. Ocelli large, distance of lateral ocellus to eye 0.8x ocellar diameter. Frons granulate and finely punctate, matte. Face with fine dense punctures and granulation, matte medially, ± shining laterally. Clypeus flat, 2.5x wider than long, with rather coarse punctures; apical margin sharp and straight. Gena densely punctate, 0.75x as wide as eye. Malar space 0.9x as long as width of mandibular base. Mandible normally shaped, with two teeth, lower one smaller and not bent inwards. Genal carina reaching hypostomal carina far from mandibular base, both carinae low.
Side of pronotum finely rugose-punctate dorsally, with longitudinal rugae ventrally. Notaulus impressed in frontal 0.3 of mesoscutum. Mesoscutum with fine dense punctures and granulation, matte. Mesopleuron and metapleuron densely rugose-punctate. Juxtacoxal carina present. Scutellum moderately convex, slightly longer than wide, densely punctate, without lateral carina. Propodeum finely rugose-punctate. Area basalis without median tubercle. Area superomedia about rectangular, slightly longer than wide; costula absent. Apical transversal carina slightly lamelliform, with blunt tooth at outer dentiparal edge. Hind coxa finely and densely punctate, without scopa. Hind femur slender, 5.0x longer than wide, with dense fine punctures. Claws not pectinate.
Areolet pentagonal, frontal distance of intercubiti c. 4x their width; 2 nd recurrent vein reaching areolet in its middle. Nervulus postfurcal (3x its width).
Metasoma strongly oxypygous. Postpetiole slightly widened apically, without distinct dorsal carina or fields, finely rugose and superficially punctate. Gastrocoelus slightly impressed, with fine longitudinal striae; thyridium oblique, 0.7x as wide as the interval. 2 nd tergite 1.2x wider than long. All tergites finely granulate and slightly shining; 2 nd tergite with some fine superficial punctures on lateral margins. 2 nd to 4 th sternites with median folds. Ovipositor sheath slender, widely extending behind metasomal apex (by length of 2 nd hind tarsomere).
Colour: Head reddish; two paramedian stripes on face, stemmaticum, base of mandible and occiput black. Antenna black; scape red ventrally, flagellomeres 11-14 with ivory rings. Mesosoma black; hind edge of pronotum and small spot on subtegular ridge yellowish; upper margin of pronotum, tegula, diffuse frontal and lateral stripes on mesoscutum and complete scutellum red. 1 st tergite black, metasoma otherwise black, with dark metallic-blue shine. Legs black; fore femur and tibia reddish-yellow frontally. Wings hyaline; pterostigma black.
♂ unknown.
R e m a r k: This new species differs from the other known species of this genus, Neolareiga rufocoerulea HEINRICH, 1980, by its stouter basal flagellomeres, black colouration of mesosoma and 1 st tergite and larger thyridium.
