Distribution. Costa Rica (type country), Panama.

Identification. This species is in the O. falicia Group, which is characterized by the dorsolateral processes on segment IX and the membranous tergum IX. This species was identified from the description and figures in the revision by Quinteiro & Holzenthal (2017). It can be distinguished from other members of this group by the very elongate dorsal lobe of tergum X, with its slightly clavate apex, the divided apex of each inferior appendage, and by the elongate, asymmetrical, dorsolateral processes on segment IX. It is most closely related to O. prolongata Flint 1981 ( Quinteiro & Holzenthal 2017).
