Extended diagnosis: Head anterior eyes conspicuously elongated, with moderately impressed transverse clypeal furrow in form of a letter V; clypeus and supraantennal plate nearly smooth, frons with distinct isodiametric reticulation; neck constriction incomplete, developed laterally as row of punctures with a wide gap at middle; labrum three-setose; mandible conspicuously elongated. Pronotum with reflexed lateral margin complete, straight but diverging in anterior half; lateral channel of pronotum of same width in its whole length, basal constriction narrow; flange flattened, six times as wide as constriction; disk smooth; with posterior angle completely rounded off but lateral margin knob like thickened. Elytron with all intervals smooth, without tubercle at declivity of third interval; striae developed as rows of distinct punctures, distance of umbilical setigerous punctures wider at middle, lateral margin at apex with distinctly widened emargination. Male genitalia ( Fig. 16 View Figs 14-20 ) with aedeagus conspicuously curved at middle, at apex flattened and distorted in ventral view, in lateral view spoon-like but asymmetrically widened at apex, rounded at tip of apex, each paramere quadrisetose. Female genitalia ( Fig. 23 View Figs 21-27 ) with coxostylus hook-like curved at apex, apically with large cone-like seta, ventromedially with thirteen nematiform setae, four of them elongated, laterotergite with three long and one short nematiform setae. Measurements. Body length 2.81-2.84 mm, width 0.93-0.96 mm, ratio length/width of pronotum 1-1.02, ratio length/width of elytra 1.64- 1.65; (n = 4).
