Description.

Size and form: Body length 1.6-1.8 mm. Body form elongate oval, convex in lateral view (e.g., Fig. 4A). Color and punctation: Dorsally bicolor, head bicolor, frons dark brown, clypeus yellow; pronotum yellow with two small black round spots along posterior margin; elytra dark brown, elytra margins paler (e.g., Fig. 4A). Ventrally dark brown; maxillary palps, mouthparts, and antennae yellow (antennal club slightly darker), legs brown. Clypeus and labrum with dense, fine, and weakly impressed ground punctation (punctures separated by 2 × their width); pronotum and elytra ground punctation fine, weakly impressed and sparser than on head (punctures separated by 3 × their width). Head: Clypeus and labrum shallowly emarginate anteromedially, lateral margins of the labrum bearing setae. Thorax: Prosternum carinate medially, strongly raised, acute and pointing anteriorly. Elevation of mesoventrite with two transversal ridges, elevated medially, lateral sides concave; longitudinal ridge broad anteriorly and sharp posteriorly, the point where the three ridges merged wide and blunt (e.g., Fig. 10C, D); elevation flat in ventral view; mesoventrite with triangular shape in ventral view. Metaventrite convex in the median region, pubescent with narrow glabrous patch on the medial and posterolateral area; anterior margin extending to mesoventrite elevation. Metafemora with dense hydrofuge pubescence along basal three-quarters of the anterior margin and along basal one-quarter of the posterior margin, then apical half of the posterior margin with sparse setae. Abdomen: abdominal ventrites very densely pubescent. Aedeagus (Fig. 8F) with basal piece 0.8 × the length of the paramere. Base of the parameres slightly narrower than the base of the median lobe, inner margins straight, then convex reaching the apex, outer margins convex, and rounded apex pointing inwards. Median lobe shorter than the parameres, approximately rectangular with apex blunt; gonopore situated at the apex of the median lobe.

Distribution.
