Diagnosis. This species differs from other members of the genus by combination of all the following characters: 1) longitudinal impression of mesopleuron ( Fig. 3 View FIGURES 1 – 8 )—unique for this species; 2) apically compressed metasoma; 3) very shallow notch of apical margin of subgenital plate; 4) fine punctures of face and mesopleuron ( Figs 2, 3 View FIGURES 1 – 8 ); 5) complete propodeal carinae ( Fig. 1 View FIGURES 1 – 8 ); 6) ovipositor with shallow impression at its middle ( Fig. 4 View FIGURES 1 – 8 ); 7) apical part of clypeus yellow ( Fig. 2 View FIGURES 1 – 8 ).

Description. Holotype female. Fore wing 5 mm long, body about 5.5 mm. Antenna with 36-38 flagellomeres. Scapus 0.58 × as long as wide. Head not narrowed behind eyes. Maximal length of temple equal to transverse eye diameter; minimal length of temple 0.67 × transverse eye diameter. Face width 0.79 × height of eye; convex, medially bulging, with oblique grooves on sides from antennal foveae ( Fig. 2 View FIGURES 1 – 8 ). Clypeus separated from face by groove; apical margin of clypeus moderately obtuse. Clypeal foveae large and deep. Malar space as wide as 0.4 of basal mandible width. Lower mandible tooth longer and wider than upper. Head shiny; face and clypeus punctate. Mesosoma shiny. Propleuron with the small lobe. Pronotum on sides distinctly punctate, shiny. Notaulus absent. Mesopleuron smooth, with longitudinal deep impression at the middle ( Opheltes species have similar furrow extending across the middle of the mesopleuron) and impression in lower fore part (resembling sternaulus of Cryptinae ) ( Fig. 3 View FIGURES 1 – 8 ). Lower part of mesopleuron punctate ( Fig. 3 View FIGURES 1 – 8 ). Epicnemial carina strongly raised. Postpectal carina present at the middle (see between coxae). Fore wing with areolet not petiolate ( Fig. 6 View FIGURES 1 – 8 ). Radius intercepting stigma at its middle ( Fig. 6 View FIGURES 1 – 8 ). Second recurrent vein with single bulla. Nervellus intercepted above middle. Nervulus slightly postfurcal. Femur length 4.73 × width; ratio of segments 1-5 of hind tarsus: 5: 2.1: 1.6: 1: 1.3. Claws pectinate with small teeth ( Fig. 8 View FIGURES 1 – 8 ). Propodeum with strongly raised complete carinae ( Fig. 1 View FIGURES 1 – 8 ).

Metasoma shiny, smooth, not punctate, slightly compressed apically. First metasomal tergite convex dorsally; its width 0.34 × length; with shallow median longitudinal impression in apical part; bordered by lateral longitudinal carinae only in apically; medial longitudinal carinae absent ( Fig. 5 View FIGURES 1 – 8 ). Glymma rather deep so that septum is semitransparent. Second metasomal tergite without longitudinal carina at base, elongate. Ovipositor straight, as long as height of metasoma, stout at base, without notch at apex ( Fig. 4 View FIGURES 1 – 8 ).

Male. Subgenital plate with very shallow notch. Parameres narrow, elongate ( Fig. 7 View FIGURES 1 – 8 ). Aedeagus not broad. Tip of aedeagus slightly curved, rounded, without flat area.

Coloration. Body mostly black ( Figs 1–8 View FIGURES 1 – 8 ). Scapus reddish-yellow, pedicellus brownish, antennal flagella dark brown. Apical part of clypeus ( Fig. 2 View FIGURES 1 – 8 ), fore and middle legs except coxae, hind femur, ventral part of hind tibia, metasomal terga except first and second tergites ( Fig. 6 View FIGURES 1 – 8 ) reddish-yellow. Basal part of mandibles, tegulae, coxae whitish. First metasomal tergite black. Stigma dark. Apical part of hind femur, dorsal part of hind tibia and tarsus, second metasomal tergite brown.

Distribution: Nepal

Etymology: The species epithet impressa refers to the structure of the mesopleuron.
