Nomenclature

 *  inca. Octostruma inca Brown & Kempf, 1960: 185, figs. 16, 29 (w.q.) PERU. Wheeler, G.C. & Wheeler, J. 1977: 600 (l.). See also: Kempf, 1968b: 400.

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

Type Material
Longino (2013) - Holotype worker: Peru, "unknown locality... probably on the Amazon drainage" (W. Weyrauch, No. 732) ; paratype workers: same data as holotype MZSP, ; non-type queen: Bolivia MCZC (MCZ paratype workers and non-type queen examined).
