Scale bar = 1 mm. 90) Dorsal habitus. Arrow indicates depression. 91) Lateral habitus. Description. Holotype female . Length 9.7 mm ; width 5.3 mm . Color : Head, pronotum and elytra piceous. Legs and venter piceous to reddish brown. Head : Frons moderately to densely punctate, punctures moderate in size. Frontoclypeal suture present, rugopunctate; punctures moderate in size. Clypeus punctate to rugopunctate, punctures moderately dense, small to moderate in size. Anterior margin of clypeus with marginal bead. Pronotum : Surface punctate; punctures sparse to moderately dense, large, concentrated on sides. Basal margin with bead and punctures obsolete medially. Disc with small depression. Anterior margin with median boss. Elytra : Punctures of striae elongate, occasionally V-shaped at base. Striae 1-3 obsolete at base. Lateral margin adjacent to humerus with 10 setose crenulations. Genitalia : Fig. 71 . Paratype . One female. Length 9.2 mm ; width 5.0 mm. The paratype differs from the holotype in the following respects: Elytra : Lateral margin adjacent to humerus with 9 setae or setose crenulations. Diagnosis. This species is best distinguished using the female genitalia ( Fig. 71 ). The inferior sclerite is as tall as the superior sclerite, and accessory sclerites are present, a combination unique to this species. Males are not known for this species. Etymology. From the Latin “ simulatus ” meaning imitation or copy, referring to the high degree of external morphological similarity found in the females of the genus. Distribution ( Fig. 92).
