Emended diagnosis. Further to the diagnosis of Bolton (2003), except eyes may be positioned more forwards (cf. O. kraussei ): forewings separated from those of other Formicinae by

combination of 5Rs notably curved towards anterior margin [towards posterior margin]; cell 3r narrow, about as long as cell 1 2r [notably longer]; cell 1 2r bounded below by Rs M notably curved towards posterior margin or bent where m-cu would be (where stub of m-cu is in Eoecophylla ) (compare Dlussky et al. 2008, fig. 2, with Dlussky et al. 2011, fig. 1, and Perfilieva 2021, plate 9, fig. 2).

Composition. Oecophylla Smith, F. , type genus, and Eoecophylla n. gen.
