Octostruma impressa Palacio 1997: 411, figs. 1D-H. Holotype worker: Colombia, Antioquia: Municipio de Frontino, Parque Nacional Natural Orchideas, 500 m NE Estación Venados, 950 m, 6 Apr 1996 (E. Palacio) [ICN, ICN-MHN-HY-5022] (not examined).

Geographic range. Colombia.

Comments. 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 has been deposited at MCZC, but a loan of all MCZC Octostruma did not contain it.
