Elytra and ventral surface of body with slight spectral iridescence, otherwise lacking. Head. Dorsal microsculpture with microlines very shallow, visible at 50x magnification, sculpticells isodiametric or somewhat irregular mesh, clypeal-ocular sulci deeply impressed, linear, divergent, extended to anterior supraorbital seta, ocular ratio 1.35-1.42, eyes average size, rounded. Labrum with anteromedial depression. Antennae: Overall length short, reaching back 2/3 length of pronotum, antennomeres 5-11 nearly quadrate. Thorax. Pronotum nearly quadrate, sides evenly rounded from apex to near base, only a very slight straightening near base, marginal bead continuous from apex to base, not extended along basal margin, basal margin not bordered, anterior margin nearly straight with anterior angles scarcely produced, hind angles (fig. 45A) obtuse and rounded, inner basal impression linear and well impressed, outer impression absent, seta at hind angle about 3x pore width forward of basal margin 1x pore width medial of lateral channel. Dorsal surface shiny, microsculpture absent from disc, visible as irregular mesh of microlines laterally and basally at 50x magnification. Elytral striae complete, well impressed and impunctate. Parascutellar stria present. Angular base of stria 1 absent. Elytra moderately shiny, microsculpture visible at 20x as stretched mesh of microlines.
