The Formicinae is a clade of ants characterised by the presence of an acidipore, a circular or semicircular terminal opening on the gaster in place of the reduced sting that is often fringed with hairs (Wheeler & Wheeler 1990). The acidopore is used to secret and/or spray formic acid, which is used for defense in lieu of a sting. Members of the Formicinae include the weaver ants of the genus Oecophylla which are found in the Old World tropics and build arboreal nests by weaving together leaves with the silk produced by larvae. The Myrmelachistini include two genera of ants sharing a reduced antennal segmentation (with nine or ten segments), five mandibular teeth and anterior tergosternal fusion on the first gastral segment. Santschiella kohli is a little known species from central Africa with very large eyes and widely separated antennal insertions with antennae passing below the eyes. Molecular phylogenetic analysis indicates a possible relationship between this species and the tropical South American Gigantiops destructor which similarly possesses large eyes but has the antennal insertions placed close together between the eyes (Ward et al. 2016).
