Further Ergatoid Gyne Records in the Ant Tribe Dacetini (Formicidae: Myrmicinae).

Variants of gynes and workers occur in a substantial number of ant species; however, dacetine ergatoid gynes have been recorded just once in the literature thus far. In the present paper, we provide abridged descriptions of five ergatoid female reproductives in five species of Neotropical dacetines belonging to two genera: Acanthognathus brevicornis Smith, Acanthognathus ocellatus Mayr, Acanthognathus rudis Brown & Kempf, Strumigenys cosmostela Kempf, and Strumigenys hindenburgi Forel. We also compare the ergatoids with conspecific gynes and workers.
