Sides rounded along their entire length, but in basal half less distinctly than in apical half; without any lateral setigerous pores. Apical margin very slightly concave or nearly straight medially, bordered only laterally. Basal margin more or less straight (very broadly rounded in some specimens), distinctly bordered throughout, width approximately equal to apical margin and slightly narrower than elytral base between humeral angles. Apical angles nearly 90° (lateral aspect), slightly protruded anteriad. Basal angles obtuse, each with small denticle at apex. Pronotal disc convex, only faintly depressed basally, markedly sloped to apical angles. Lateral depressions varied, from very narrow along entire length, indistinct, and with area at basal angles convex, to distinctly widened and deepened in basal third and depressed at basal angles. Basal foveae small, either flat or slightly impressed. Pronotal surface densely and distinctly punctate, mainly along sides laterobasally and lateroapically, with punctation more widely distributed over entire basal and apical portions in some specimens, or with very fine punctures also present in central portion in a few specimens, or with punctation restricted only to lateral and latero-basal areas in a few other specimens; in all specimens, punctures coarsest in latero-basal portion and in narrow area along sides.

Metatarsi approximately equal in length to minimum linear distance across neck constriction just behind eyes in males, slightly shorter in females; tarsomere 1 distinctly longer than tarsomere 2, but distinctly shorter than tarsomeres 2+3. In males, protarsi markedly enlarged (tarsomeres 2-4 much wider than long, tarsomere 1 about as long as wide, and tarsomeres 1-4 with adhesive vestiture ventrally); mesotarsi moderately enlarged (tarsomere 1 slightly longer than wide; tarsomere 2 approximately as long as wide; tarsomere 3 about 1.3 times as wide as long; and tarsomere 4 distinctly smaller than tarsomeres 2 and 3, and deeply concave apically, and tarsomeres 2-4 with adhesive vestiture ventrally).</paragraph>
