Antennae reaching slightly beyond base of clypeus, second segment 1.5 times length of first. Lateral pronotal carinae diverging, curved, not reaching hind margin. Hind basitarsus as long as or slightly longer than the other two together; spur large, as long as basitarsus, broad, laminate, concave on inner surface, numerous (15 to 20) distinct teeth on hind margin.
