While this genus was originally placed in the subfamily Formicinae, Bolton (in the 1 July 2012 release of his NGC) considers it to be incertae sedis within the Formicidae and thus unplaced to subfamily.
The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.
