(Subfamily Myrmicinae)


The genus was first described by Forel (1890) as Trigonogaster, but the name was preoccupied by a pteromalid chalcid, so the new name Recurvidris is proposed by Bolton (1992). It was classified into the tribe Crematogastrini by Bolton (2003).

Vietnamese Recurvidris spp. inhabit forest edge and woody habitats, but rarely grasslands. They nest in the soil and built a chimney-formed mound on the nest entrance with soil particles.
