ate. Antebasal row of punctures impressed; disc densely punctuate, punctures round and well delimited, puncture intervals mostly a little larger than diameters. Elytra with humeral protuberance indistinct, apical portion moderately impressed; discal punctation similar to that of pronotum, punctures on apical portion slightly larger; discal row of punctures absent; basal stria row impressed, with punctures about as coarse as those of pronotal antebasal row; sutural stria row of punctures relatively fine. Prohypomera smooth with very fine and sparse punctures mainly on outer half. Mesepisterna smooth with moderately dense, moderately fine, and very shallow punctures. Exposed abdominal sternites and tergites with coarse and relatively sparse punctures and densely reticulate microsculpture. Legs long, mesotibiae and metatibiae slightly curved.

Male. Metasternum impressed in middle, with long semi-erect pubescence. Profemora (Fig. 18) with tubercles arranged in three rows on ventral side. Protibiae (Fig. 18) slightly incurved with a small apical angle and tubercles on inner side. Variation of internal sac of aedeagus as in Figs 14–16.

Diagnoses. This is a rather variable species, especially in body size and punctuation ( Löbl 1992). Among the material we examined was one male from Hainan Prov. with three blurry rows of puncture consisting of coarse punctures.
