Elytra oblong-oval, rather wide, with sides evenly and slightly arcuate, markedly flattened on disk, widest after their mid-length. Humeri marked, though broadly rounded, elytra wider at level of preapical sinuation than at humeral level. Each elytron slightly sinuate at level of umbilicate pore 8 and separately rounded at apex. Elytral striation moderately deep, striae rather regular, the outers shallower, though even stria 7 visible in its median portion. Occasionally, some striae slightly waved. Inner interspaces, at most, subconvex, outer ones flat. All interspaces subequal in width except for interspace 1, which is evenly narrow, and interspace 2, which is much wider posteriorly than other interspaces. Elytral striae finely punctured.

of apical striation: ((2x3)x4)((5x6)x7)xAS but this pattern is not stable, since apical striole can join any of striae 5–7. Apical striole evenly curved, deep in its posterior part, gradually shallowing and straightening in anterior part. Parascutellar striole distinct. Apical triangle markedly elongate, its inner side nearly parallel to body axis. Angulo-apical pore twice as far from preapical pore as from exterior one. Preapical pore usually located on interspace 3 at level of anterior termination of carinula near apical striole, much more rarely in stria 2. In the latter case, interspace 2 markedly widened in posterior part. Lateral groove of elytra average, margins slightly reflexed. Basal portion of the lateral border directed toward anterior termination of stria 4.

Apical portion straight, without distinct button-like dilation or apical disc. Viewed dorsally, median lobe rather thick, nearly parallel-sided, slightly narrowed toward the apex, which is broadly rounded. Basal orifice moderately emarginate. Sagittal lobe of medium size. Parameres rather long, clearly narrowing distally, obliquely truncate and rounded apically, each bearing 4 apical setae. Left paramere clearly longer, with a well-developed ventral apophysis. Endophallus armature consisting of two rather large and moderately sclerotized pieces located in middle part of median lobe. Proximal piece larger, subtriangular or trapezoid in lateral view, located near left wall of median lobe. Distal one located largely in horizontal plane and covered with a sparse scaly mesh from above.
