Turneria collina

This species, known from a single specimen, is one of the most distinct in the genus and also the largest currently known. The collection site, at an elevation of 1600 meters, is unusually high for the genus. The next highest collection site for Turneria is 1000 meters and most collections are below 100 meters.

Identification
Frontal lobes without erect hairs, lateral areas of head weakly imbricate and with integument shiny, area between propodeal protuberances flat, head and thorax reddish brown and gaster dark reddish brown. The clypeus possesses 22 erect hairs. This species differs from all other known species in the following measurements: ES, PpW, MH and PpH. It also differs from other Turneria by an additional 3 to 16 metric characters.
