Distribution Notes:



Palacio (1997) reports the measurements of this species as HW 0.67–0.77, HL 0.65–0.75, CI 102–103. From the description, it seems to combine characters of O. inca and O. balzani. The head size and shape, the large compound eyes, and the impressed metanotal groove are similar to O. inca. The mandibular dentition and the basal scape lobe are apparently like O. balzani. The original publication indicates that a paratype was deposited at MCZC, but Longino (2013) did not find it among MCZ material.
