Head shiny, unpunctuated, with eyes strongly protruding laterally. Antennal segments 1 short, 2 - 7 varying in size, but all noticeably longer than wide, 8 spherical, smaller than 7, and its three-segmented, nearly parallel club distinctly, but not sharply demarcated. Pronotum one-third wider than long (1.3:1), shiny with extremely fine and widely spaced punctation, greatest width in the anterior third, rounded from here to the front, straight and barely converging narrowed towards the rear, with very weak bulging elevation before the base. Elytra narrower than long (1:1.36), shiny, and in the anterior half with moderately dense, strong, and distinctly wrinkled punctation, which becomes much finer and more widely spaced towards the tip in the posterior half; greatest width just before the middle, sides evenly rounded. Basal foveae round and deeply excavated, not flattened laterally, small tomentose cushions in the middle of the anterior margin. In the male, anterior tibiae slightly thickened, with weak indentation on the inner side in the apical third ( Fig. 34 ). Underside: Jwith metaventrite is shiny, sparsely haired in the centre, and more densely haired towards the sides, moderately impressed in the middle. In the centre of this notch, nearly unpunctured, punctures become clearer towards the bulging edges and are uniformly strong and moderately densely punctuated on the outer sides ( Fig. 33 ).
