Type Material. Holotype female (property of Dave Carlson) at UNSM labeled: a) “ Ecuador Napo Pr. // Aliñahui, 21 Km E // Atahualpa , at lights // 3 April 2000 // Coll. D.C. Carlson. ” (printed, rectangular label)/ b) my holotype label.

One paratype female at MIZA labeled: a) “ Colombia // Gigante Huila // VII-1979 ” (handwritten, rectangular label)/ b) “Col. // O. Rojas” (handwritten, rectangular label) / b) my printed paratype label.

Type locality. Ecuador, Napo Province, Aliñahui.(21 km E of Atahualpa)

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.

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.
