Diagnosis

Vertex as long submedially as broad at base, obtusely rounding into frons, as wide at apex as at base, lateral margins straight, apical margin truncate or slightly convex with submedian carinae slightly prominent, Y-shaped carina distinct, submedian carinae uniting at apex of vertex, basal compartment of vertex wider at hind margin than greatest length and than median length; frons in middle line longer than wide at widest part, widest at middle, lateral margins shallowly convex; median carina simple or forked only at extreme base; clypeus at base a little wider than frons at apex, postclypeal disc shorter in middle line than broad at base, in profile rather strongly convex so that entire clypeus in profile is rather strongly convex; rostrum with subapical segment surpassing mesotrochanters, apical segment attaining post trochanters; antennae reaching little beyond frontoclypeal suture, basal segment longer than broad, second segment longer than first. ocelli present, rather small. Pronotum with disc longer in middle line than broad at anterior margin, lateral carinae concave, not very strongly diverging, not attaining hind margin; post-tibial spur with 13–15 teeth. Dark castaneous; carinae of frons and clypeus, vertex, pronotum and mesonotum, antennae, rostrum, legs and abdominal sternites in female in part, and ovipositor, testaceous. Anal segment of male short, ring-like, laterapical angles moderately close to one another, each produced ventrolaterad in a stout flattened spinose process, at base of segment on each side ventrally a long thin spine directed ventrad. Pygofer moderately long, posterior opening as broad as long, dorsal margin broadly excavate, dorsolateral angles moderately produced, obtuse in side view, diaphragm narrow with dorsal margin V-shaped and produced medially dorsad in a long bifurcate lobe; medioventral process absent. Aedeagus rather long, tubular with a ridge along ventral margin, orifice subterminal, directed ventrad, apex slightly decurved. Genital styles moderately long, inner margin at base moderately produced caudad, thence margins sinuately parallel, outer apical angle acute, inner apical angle reflected in an obtusely angulate flange. First valvifers of ovipositor not produced mesad at base. Pregenital sternite not forming a sclerotised lobe. Male (brachypterous) length 2.0 mm. Female (brachypterous) length 3.6 mm (Fennah 1965).
