Finally, the microsculpture is less upraised overall: 1, vertex with well-developed isodiametric sculpticells in transverse rows; 2, pronotal disc with well-developed slightly transversely stretched mesh, the median base covered with a mixture of isodiametric and transverse sculpticells; 3, elytral disc with a transverse mesh, sculpticell breadth 2

The pronotal lateral marginal depression is only slightly broader at the front angles, the angles tightly rounded. The mesepisternum is moderately punctate, with ~9 punctures in 1-2 longitudinal rows. Finally, the male median aedeagal lobe has a less developed dorsal projection and narrower, more rounded apex (Fig. 58
