Eyes small, hemispherically prominent, their frontal interocular distance 1.25 times eye diameter. Antennae shortly flabellate, 11-segmented, covered with short, dark colored setae (Fig. 19). Pronotum flat, transverse, 1.19 times wider at base than length at midline; frontal margin projected forward; lateral margins slightly elevated, convex, posterior angles acutely projected, pronotum with moderately robust median areola, attached to middle of basal margin of pronotum, connected to anterior margin by keel occupying one third of midline, lateral keels absent.
