Species : banksi new combination , bispinosa revived combination , † brunoi , cuneiforma new combination , enodis new combination , ingeborgae new combination , insularis new combination , lanei new combination , laticephala new combination , lineolata new combination , lucaris new combination , mecotyle new combination , mediatrix new combination , menozzii revived combination , perspicax new combination , rastrata new combination , semiferox new combination , triangularis new combination , and wilsoni new combination ( and the junior synonyms schubarti new combination , trigona new combination , aculeaticoxae new combination , and triangularis richteri new combination ). Distribution: Exclusively Neotropical, occurring from Guatemala to Uruguay , and in the Caribbean islands of Hispaniola and Lesser Antilles. Notes: Here we revive the name Poneracantha from synonymy under Gnamptogenys to include all the species representing the previous rastrata group sensu Lattke (1995) . All Poneracantha species can be identified using the work of Camacho et. al. (2020) under the previous combination in Gnamptogenys .
