Legs: yellowish with brown, dense punctures and dense, pale vestiture; femora with pale, convex, unpunctured ring in distal part; tibiae short, with longitudinal furrow dorsally margins of this furrow furnished with small, black tubercles and thin hairs, longer than those present on remainder of tibiae. Scutellum: almost 1.6 times as long as its width ( Fig. 1 B); anterior margin slightly concave; coloration yellowish brown, with deep brown punctures and variable black brown longitudinal spots and stripes; basal part with two distinct, convex, yellow callosites, each situated mediolaterally. Pregenital abdomen: abdominal sterna separated by pale brown intersternal sutures; coloration variable, yellowish to pale brown, deep punctures present in lateral parts of the sterna; posterolateral angles dark, produced into small spine; pale vestiture dense ( Fig. 1 B).
