Corrieopone nouragues gen. nov., sp. nov., a new Ponerinae from French Guiana (Hymenoptera, Formicidae)

This study describes the worker and queen castes of the Neotropical ponerine Corrieopone nouraguesgen. nov., sp. nov., an ant from the tropical rainforest in French Guiana. Worker morphology of the taxon is compared with those of other Ponerinae and the similarities between them are discussed, refining the definition of character states for some diagnostic characters at the generic level, providing an identification key to the Neotropical genera, and making some adjustments to the taxonomic framework within the subfamily. Descriptions, diagnosis, character discussion, identification key, and glossary are illustrated with more than 300 images and line drawings. Open science is supported by providing access to measurement data for specimens of the new genus, a matrix of character states for all ponerine taxa evaluated in this study, and specimen data for all examined material. The new or revived combinations presented here are Pachycondyla procidua Emery, comb. rev., Neoponera curiosa (Mackay and Mackay), comb. nov., Leptogenys butteli (Forel), comb. nov., and Bothroponera escherichi (Forel), comb. nov. In addition, Leptogenys butteli is synonymized with Leptogenys myops (Emery), syn. nov.
