Diagnosis. This species is best distinguished from other species using the female gonocoxites ( Fig. 77 View Figures 65-77 ), which are similar in form to those of A. howdenorum ( Fig. 68 View Figures 65-77 ) and A. candezei ( Fig. 66 View Figures 65-77 ). Aegidinus venezuelensis lacks the transverse ridge on the superior sclerite (present in A. candezei ). In A.

venezuelensis, the spinulous region on the interior of the superior plate projects downwards, while in A. howdenorum , the spines project inwards. No males are known for this species.

Etymology. This species is named for the country in which the type originates.
