<paragraph pageId="38" pageNumber="39">Body length 3.4-4.6 mm. Shape short and wide, moderately convex. Eyes moderately prominent in both sexes. Labrum black, dorsum of head melanic with strong metallic luster. Pronotum with remarkably large central melanic spot, without a testaceous median line, in most specimens with a metallic sheen; sides of the pronotum testaceous. Scutellum black. Elytra testaceous with small melanic spot in the normal generic pattern, save for a pair of additional spots which delimit the humeral humps on their ventral side and extend over a short stretch of the ninth interstria. Venter of thorax and abdomen melanic. Maxillary palpi darkened on apical one-third of distal segment. Femora with pubescent portion darkened, glabrous portion testaceous.</paragraph>

<paragraph pageId="38" pageNumber="39">Head coarsely and densely punctured, punctures on frons about twice the size of ommatidia. Pronotal punctures larger than the ones on head, round, dense, irregular in spacing. Ground sparsely and finely micropunctate, shining. Scutellum with a few deeply impressed punctures, smaller than pronotal ones; ground alutaceous. Elytral striae shallow, not distinctly impressed, with coarse punctures about the same size as pronotal ones, overflowing outwards. Interstriae wide, flattened, bearing punctures smaller than those on striae, 1-2 seriated; outer interstriae slightly convex; background smooth in males, reticulate in females. Elytral apices simple. Spine-like hairs absent.</paragraph>

<paragraph pageId="38" pageNumber="39">Mesoventral process small, laminar, with curved anterior tooth pointing downwards, a little thickened; posterior tooth raised but less prominent than anterior one. Metaventral process wide, flat. First ventrite carinate in anterior half, without lateral depressions. Ventrites second to fourth not carinate. Fifth ventrite with shallow apical notch, the bottom of the latter bearing two short rounded teeth.</paragraph>

<paragraph pageId="38" pageNumber="39">Maxillary palpi short, with second palpomere short and thick. Basal pubescence of mesofemora and of metafemora slightly oblique, extending to a little less than half of the femoral length on anterior margin, and a little more than half on the posterior margin. Protarsus of male with basal tarsomere weakly thickened, bearing adhesive sole, about twice as long as the second tarsomere that does not bear a sole. Claws weakly arched, angular at base, bearing a small sub-basal tooth.</paragraph>

<paragraph pageId="38" pageNumber="39">Male genitalia (Fig. 17C): basal piece two-fifths of total length. Parameres acuminate, in lateral aspect almost sickle-shaped, in tergal aspect weakly and regularly curved inwards. Apices broadly rounded; short subapical row of hairs. Median lobe a little shorter than the parameres, cylindrical and rather slender in basal three-fifths, very thick and subconical in apical two-fifths, with a sternal ridge.</paragraph>
