); pro- and mesosternum brownish yellow; metasternum dark brown; legs pale brownish yellow; abdomen yellow. Head without punctures; pronotal punctures small, separated by a diameter or less; elytral punctures larger than on pronotum, separated by less than a diameter to twice a diameter, becoming gradually larger toward lateral margin; prosternal punctures small, indistinct, mesosternal punctures large, separated by less than a diameter, metasternal punctures large, separated by two or three times a diameter medially, absent in lateral 1/3; basal abdominal ventrite with coarse punctures separated by about a diameter medially, lateral 1/3 of ventrite lacking punctation, ventrites 2–4 finely punctured, punctures separated by about a diameter, ventrite 5 with dense, fine punctation. Head with frons parallel-sided, medially depressed, 1.5 times as wide as eye, apex truncate medially, lateral 1/8 slightly retracted, angle acute (

Epipleuron strongly descending externally. Postcoxal line on basal abdominal ventrite evenly curved, extended 2/3 distance to rear margin of ventrite.
