COMPENDIOUS DESCRIPTION

A small sized piceous subcylindrical species with the following measurements: body length 6.05 / 6.15 mm, width 1.59 / 1.68 mm, ratio L/W of pronotum 1.05 / 1.09, ratio L/W of elytra 1.99 / 2.0 (n = 2). Labrum seven-setose, indistinctly trilobed anteriorly. Head with clypeus smooth. Median part of clypeus straight, separated from clypeal wings by distinct small notches, clypeal-wings directed laterally. Eye prominent but small, gena enclosing eye posteriorly by one third, E/G 9:7. Clypeo-frontal furrow flattened. Neck constriction formed by belt of medium sized punctures. Frons moderately convex, with scattered punctures laterally and posterior to flat clypeal suture, facial carina and facial sulci developed as usual. Pronotum ( Fig. 3 G View Fig ) peltate, longer than wide, distinctly convex in frontal view, moderately convex in lateral view, with lateral margin nearly parallel, widest and slightly convex behind middle, anterior angle slightly projecting, posterior angle small but pointed, lateral margin almost smooth, disk with minute scattered punctures, with short indistinctly impressed line bilaterally at posterior third formed by small punctures, with isodiametric reticulation at basal declivity. Proepisternum with rough coreaceate surface, laterally with distinct transverse wrinkles. Elytra ( Fig. 1 E View Fig ) subcylindrical, striae one to four ending free at base, interval three with four setigerous punctures, intervals moderately convex, interval seven and eight with isodiametric reticulation, other intervals smooth, glossy; interval eight carinate at humerus and apex, third at base with tubercle.Abdomen with isodiametric reticulation, tile-like at middle, with medium sized punctures including last visible segment, two apical setigerous punctures widely separated. Hind wing fully developed. Intermediate tibia with six tubercles with setae above the spur at the lateral side. Protrochanter with acute tooth at apex, tarsomeres of same size.

Male genitalia ( Fig. 4 E View Fig ). Aedeagus nearly regular arcuate, at apex with moderately elongated and flattened spatula, spatula widened out at apex. Parameres asymmetrical, hyaline apically, with small group of fine pili at apex.

Female gonocoxite and epipleurite ( Fig. 5 H View Fig ). Gonocoxites falciform, robust,evidently sclerotized, with gonocoxites nearly completely fused, with two long setae, one of them distinctly stronger, with four medium sized setae. Epipleurite triangular, formed by a stable velum furnished at margin with a row of three setae and an additional seta basally.

Variation. On the frons the scattered punctures vary in number and position. The band of punctures forming the neck constriction varies slightly in the number of punctures.
