Gesomyrmecini

The tribe Gesomyrmecini belongs to the subfamily Formicinae. For a list of genera contained within this tribe see Gesomyrmecini genera, for species see Gesomyrmecini species.

Ward et al. (2016) - The tribe Gesomyrmecini is here restricted to Gesomyrmex and two similar fossil taxa (Wheeler 1915). Bolton (2003) also placed Santschiella in Gesomyrmecini, but the molecular results do not support a close relationship between Gesomyrmex and Santschiella (Blaimer et al. 2015). The similarities between the two—very large eyes, widely separated antennal insertions, and scapes that pass below the eyes (Bolton 2003) - must be interpreted as due to convergence.
