Nomenclature

 *  impressa. Octostruma impressa Palacio, 1997: 411, figs. 1D-H (w.) COLOMBIA.

Longino (2013) - 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 Octostruma inca and Octostruma 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 MCZ, but a loan of all MCZ Octostruma did not contain it.
