Diagnosis. This species differs from the other known Nepalese members of Lathrolestes by the large size (8 mm.), distinctly raised propodeal carinae, costula absent and fused area basalis and area superomedia ( Fig. 7 View FIGURES 7 – 12 ), the ovipositor projecting far beyond the metasoma ( Figs 2 View FIGURES 1 – 6 ), and coloration of body. From other species of the genus, this species differs by a longitudinal groove at hind part of mesopleuron and impression at lower fore part resembling the sternaulus of Cryptinae .

Description (Holotype female). Fore wing 6 mm long, body 8 mm. Antennal flagellum with more than 30 articles. Width to length ratio of scapus 0.5. Head not narrowed behind eyes. Maximal length of temple to transverse eye diameter ratio 0.82; minimal length of temple to transverse eye diameter ratio 0.5. Face width to longitudinal eye diameter ratio 1.16. Face convex, with strong protuberance. Clypeus separated from face only at its middle by slight shallow impression; apical margin of clypeus moderately obtuse. Clypeal foveae small. Malar space as wide as 0.33 of basal mandible width. Outer face of mandible without impression at base. Lower mandible tooth as long as upper, lower margin obtuse. Head shiny; face and clypeus punctate.

Mesosoma shiny. Propleuron with strong lobe. Pronotum laterally, mesoscutum and scutellum smooth and shiny, distinctly punctate. Notaulus distinct. Mesopleuron smooth, not punctate, with longitudinal groove at hind part ( Opheltes species have a similar furrow) and impression at lower fore part (resembling sternaulus of Cryptinae ) ( Fig. 8 View FIGURES 7 – 12 ). Epicnemial carina strongly raised. Postpectal carina twice present at the middle (see between coxae). Areolet of fore wing not petiolate. Radius intercepting pterostigma behind its middle. Second recurrent vein with a single bulla. Nervellus intercepted below middle. Nervulus postfurcal. Femur 5 times as long as wide laterally; ratio of segments 1-5 of hind tarsus 2.72: 1.25: 1: 0.6: 0.75; tarsal claw long with 4 high oblique teeth ( Fig. 16 View FIGURES 13 – 16. 13 ). Propodeum with distinct carinae ( Fig. 7 View FIGURES 7 – 12 ). Costulae absent. Area superomedia and area basalis fused. Basal part of dorsal carina zigzag shaped.

Metasoma dimly shiny, densely punctate. First metasomal tergum width to length ratio 0.58; with shallow median longitudinal impression; bordered by lateral longitudinal carinae; medial longitudinal carinae inconspicuous, apically absent. Glymmae rather deep. Second metasomal tergum transverse, with longitudinal carina at base (similar character in Ctenopelma ). Ovipositor straight, elongate, almost half as long as metasoma, without notch but with impression and nodus at apex.

Head, prothorax, fore part of mesonotum, apical part of hind tibia and metasoma (except part of first tergum) brown with slight metallic violet tint. Other parts of body reddish-yellow including antennae, maculae on head, apical part of clypeus, mandibles, tegulae, basal and apical part of first metasomal tergum. Fore and middle trochanters, and apical tarsal article white ( Figs 1, 2 View FIGURES 1 – 6 ).

Etymology. The species named for Nicholas Roerich, Russian painter, philosopher, and orientalist who studied the Himalayas.
