Remarks. Some examined ZRC material were originally identified as ‘ Gnamptogenys costata (Emery, 1889) ’, but that was considered a junior synonym of ‘ G. coxalis’ (Lattke & Delsinne 2016). Genus initially determined as Gnamptogenys, but present species combination revived in Camacho et al. (2022) based on phylogenetic evidence.
