Head with sparse and fine punctation, denser in middle, holotype and two paratypes with indistinct punctures; punctation of pronotum moderately sparse, distinctly larger and deeper than that in middle part of head, finer and sparser in middle and posteromedial portions (two paratypes without punctures in posteromedial part); elytra with dense, large and deep punctation, usually finer and sparser in middle.
