Discussion: Easily recognizable from other species of Dilasia by the punctures typical of those seen in Lasiochilus , though not as deep as in this genus. However, the other characteristics of Dilasia are presents in this species: male genitalia with a row of teeth on the inner margin of foretibiae, series of teeth on foretrochanters, and the grouping of apically acute, spiniform copulatory teeth on apical left margin of sternite VI, as well as a nearly straight left paramere.
