Diagnosis

Length = 2.9–3.7 mm. Head: frontal tubercles not distinctly delimited posteriad, supracallinal sulcus effaced. First antennomere distinctly shorter than second and third together. Pronotum: subquadrate, slightly constricted antebasally, narrowly margined. Anterolateral callosity obtuse­angled, well developed and slightly asymmetrical. Surface covered with very coarse punctures on disc and slightly finer ones on basal region ( Fig. 3 ). Elytra: striae completely irregular because punctures are duplicated and disordered (more strongly in females). Punctures large and deep. Interstriae slightly convex and narrower than double rows of punctures. Base of sixth elytral stria strongly impressed, deeper than the other striae. Aedeagus: almost parallel sided in ventral view, produced apically into an acute point ( Fig. 9 ). Vaginal palpus: poorly developed, extremely short and narrow ( Fig. 15 a). Spermatheca: as in Fig. 15 b.
