Collar developed; pronotum wider than long, anterior pronotal lobe distinctly shorter and narrower than posterior ( Fig. 1 ); anterior pronotal lobe longitudinally depressed at middle; posterior pronotal lobe much wider than anterior, anterior portion widely depressed along middle, along middle depression with two longitudinal carinae ( Fig. 1 ), lateral angles rounded; scutellum unarmed; fore and mid femora obviously thicker than hind femur, fore and mid tibiae obviously bent and with small sponge furrow each.
