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

Systematics, Morphology and Physiology


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.

We would like to thank the collectors of the specimens here described and to Rogério R. Silva, Tiago Carrijo, and Rodolfo Probst for assistance with the formulation of the R scripts, especially regarding graphical parameters. Fernando Augusto Schmidt cordially loaned us an ergatoid of Strumigenys cosmostela, which was deposited in the Formicidae collection of the Universidade Federal de Viçosa. Also, three anonymous reviewers contributed with valuable comments and suggestions. We acknowledge the support by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior in the form of a grant to TSR Silva (CAPES) and support by Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) and Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) to CRF Brandão.
