Frontal furrows regularly impressed, subangulate, approaching one another in middle; frons convex. Supraorbital setae located in lines, slightly convergent anteriad, posterior seta far behind posterior margin of eye. Pore of anterior supraorbital seta markedly foveolate that of posterior seta slightly so. Mandibles stout, evenly curved.

Its sides evenly and broadly arcuate, barely sinuate before hind angles, latter rather small but distinct, subrectangular. Posterior margin straight medially, obliquely truncate laterally; anteri- or margin straight. Anterior angles marked but not salient. Lateral margins narrowly bordered and slightly reflexed, lateral groove of average width, slightly expanded posteriorly. Prebasal transverse impression shallow, vaguely delimit- ed, angularly curved in basal foveae, the latter rather small and shallow. Apical transverse impression irregular, occasionally interrupted medially.Discal foveae missing or slightly impressed. Anterior marginal seta placed in about anterior third of pronotum, posterior seta in hind angle. Base of pronotum distinctly rugose. Median line distinct, slightly impressed, deepest at level of prebasal transverse impression.</paragraph>

Elytra oval, with evenly arcuate sides, widest just after their mid-length. Humeri broadly rounded, prehumeral margin evenly arcuate, posthumeral sinuation indistinct.

Stria 2 surpassing level of preapical pore, with or without distinct connection with stria 3, latter joining stria 4 at level clearly behind anterior termination of apical striole. Striae 5 and 6 joining each other slightly behind median group of umbilicate series or near that level; stria 7 without clear connection with any of other striae. Both parascutellar striole and parascutellar seta present. Apical recurrent striole of average length, deep and straight anteriorly, usually surpassing level of mid-distance between umbilicate pores 7 and 8 anteriad, joining fused stria (5x6) anteriorly. Striation on apical slope as follows: ((5x6)xAS)(3x4)(2x3). Apical triangle usually subequilateral, inner sides of apical triangles of both elytra subparallel to body axis. Preapical pore placed at level of umbilicate pore 8 or slightly behind. Angulo-apical pore usually set closer to exterior pore than to elytral suture. Lateral margins bordered and narrowly reflexed in posterior part while moderately reflexed in anterior part.

but differs in having larger size, flatter and longer eyes, less transverse pronotum with sides more deeply sinuate before larger hind angles, which are more produced, basal margin narrower, basal surface more coarsely rugose; elytra more elongate; apical recurrent striole longer, surpassing level of mid-distance between umbilicate pores 7 and 8; lateral margins of both pronotum and elytra less markedly reflexed (the differences in morphometric characters are shown in Table 2).
