Diagnosis

Morphology. Body length: ♂ 4.2–5.1 mm; ♀ 4.3–5.5 mm. Head: Head including eyes slightly narrower or about as wide as pronotum. Vertex much broader than wide in midline; anterior margin straight or weakly angulated; lateral margins strongly elevated; subapical carina absent. Frons invisible in dorsal view; broadening over very short distance, therefore lateral carinae distinctly concave; lateral carinae strongly elevated; position of maximum width of frons distinctly dorsad of centre of frontoclypeal suture; median carina incomplete or complete. Frontoclypeal suture distinctly semicircular, bent upwards, median part not reaching lower margin of antennal scape. Lateral carinae of anteclypeus well developed. Rostrum distinctly surpassing hind coxae, attaining level of middle of hind femora; subapical segment 1.2–1.9 times longer than apical segment. Thorax: Mesonotum with lateral carinae straight or slightly curved, not sinuate. Forewings steeply tectiform; Sc+R fused, forming common stem Sc+R, M emerging separately from basal cell; Sc+R and M emerging from basal cell distinctly separately from CuA; Sc+R forking basad of fork CuA1+CuA2; crossvein MP-CuA (=M3+4-Cu1a) much shorter than MP (M3+4) from M fork to crossvein and much shorter than crossvein R-M; RP apically bifid; MA apically trifid; 10 apical cells. Hindwing with R unforked. Hind leg: tibia with 6 apical teeth (innermost tooth smallest and least sclerotised); 1st tarsomere with 6 apical teeth. Female genitalia: Ovipositor elongate, orthopteroid, slightly curved upwards, reaching but not surpassing anal style; 8th sternite medially very long, slightly bent dorsad, posterior margin u-shaped; anal segment square (as long as wide) or slightly trapezoid (narrower at apex) in dorsal view; anal style longer than wide; 9th tergite without wax plates.
