Palp formula 3, 2. Mandibles well developed, subtriangular, masticatory margin with larger basal tooth, four minor sharp teeth and much longer sharp apical tooth. Median portion of clypeus evenly convex, without median and lateral carinae, its anterior margin convex, without a notch. Scutum with broad notauli. Propodeum distinctly angulated in profile, its dorsal surface delineated laterally by sharp longitudinal ridges. All meso- and metatibiae with well-developed simple spur, pretarsal claws simple. Forewing with closed cells 1+2r, 3r and mcu; cell 3r relatively short, about the same length as cell 1+2r; free vein M branching off from RS approximately at the midlength between junction of cross-vein 2r-rs with RS and vein m-cu; cross-vein cu-a located far from base of wing, so that branch 1M+Cu much longer than 2M+Cu, Icu = 1.75, Icua = 1.28.

Body length 4.1 mm. Head subglobular, slightly wider than long, gradually rounded behind eyes, without marked occipital corners and with convex occipital margin. Eyes very large, their maximum diameter half of head length, situated distinctly in front of mid-length of sides of head, so genae very short. Ocelli large, forming obtuse triangle, diameter of central ocellus subequal to width of scape. Frons relatively narrow, 0.25 head width, frontal sockets fully exposed. Frontal triangle well marked. Mandibles quite long, ca. 0.4 head length. Apical segment of maxillary palps twice as long as preapical one. Antennal scape ca. twice as long as width and ca. 4.5 times shorter than head. First funicular segment very short, somewhat shorter than wide and half as long as second segment; all subsequent segments of same width; second to 11th segment subequal in length, last segment twice as long as second one. Whole head with coarse reticulation, clypeus with sinuous longitudinal rugae, its central part and mandibles smooth; eyes surrounded by narrow foveate groove. Temples and occipital margin with quite numerous subdecumbent hairs of moderate length; antennal scape with sparse subdecumbent, but quite long hairs; funicular segments with very short and abundant decumbent to subdecumbent pilosity; anterior clypeal margin without long setae, with only a few short, thin hairs; mandibles with quite long semierect hairs.</p> <p>Mesosoma 1.6 times as long as high, scutum moderately convex, posterior surface of propodeum 1.2 times as long as dorsal one. Notauli deep and wide, distinctively arched in profile view, with coarse short transverse rugae (foveate). Petiole with distinct peduncle, 1.6 times as long as high, its node with widely rounded dorsum; postpetiole subglobular, slightly higher than petiole. Spurs on meso- and metatibiae relatively long, equal to width of tibia at point of their articulation. Scutum, scutellum and propodeal dorsum with coarse reticulation; sides of pronotum, mesopleura and lower part of sides of propodeum smooth; gaster smooth.</p> <p>Mesosoma, waist and gaster with moderately dense erect to semierect hairs, legs with decumbent to subdecumbent pilosity, femora with additional longer suberect hairs. Genitalia small and barely visible. Forewings: pterostigma rather long and narrow; cross-vein rs-m completely reduced, so that cell rm absent; cell mcu of moderate size, trapezoidal, its height subequal to midline, its distal point does not reach level of basal end of pterostigma, vein section 1RS+M somewhat shorter than 1Cu; cell 1+2r heptagonal, relatively short, veins 1R1, 2R1 and 3R1 of nearly equal length; vein sections 2RS+M and 3RS subequal in length; cross-veins 2r-rs and 1RS well developed, 1RS slightly inclined toward base of wing, 2r-rs almost perpendicular to 2R1 and 3R1 at the point of their junction.</p> <p>Measurements</p> <p>(in mm).
