The combination in the worker of large compound eyes with many ommatidia, antennal scrobe a shallow impression without carinate rim, base of scape lacking flattened anterior lobe, and HW > 0.68 uniquely identify this species.


The measurements reported in Brown and Kempf (1960) for the holotype of O. inca are considerably larger than the six workers measured in Longino (2013). HW of six measured workers, including three paratypes, was 0.69–0.87; HW of the holotype was reported as 0.91. The larva described by Wheeler and Wheeler (1977) was a specimen from Colombia sent by W. L. Brown. MCZC material examined by Longino (2013) included what appeared to be two nest series collected by W. L. Brown in Dept. Valle, Colombia.
