Head with dense punctures separated by a diameter or less; pronotal punctures small, separated by a diameter or less; elytral punctures larger than on pronotum, separated by up to twice a diameter; prosternal punctures small, indistinct, separated by about a diameter; mesosternal punctures larger than on prosternum, separated by less than a diameter; metasternal punctures small, separated by two or three times a diameter medially, absent in lateral 1/3; basal abdominal ventrite with coarse punctures separated by about three times diameter medially, ventrite 2 with coarse punctures in median 2/3 separated by less than a diameter, ventrites 3, 4 finely, densely punctured medially; ventrite 5 finely, densely punctured.
