Hylomyrma villemantae sp. nov. (Hymenoptera: Formicidae), a New Ant Species from Mountain Rainforests of the Atlantic Forest Biome

Marilha da Silva Neves, Benoit Jean Bernard Jahyny, Lucimeire de Souza Ramos Lacau, Michele Silva D'Esquivel, Muriel Lima de Oliveira, Jacques Hubert Charles Delabie, Sébastien Lacau


A new species of Myrmicinae, Hylomyrma villemantae Neves and Lacau (Hymenoptera: Formicidae), is described after the morphology of the worker. This species is easily distinguished from any other ones in the genus by a unique combination of characters, including the fourth abdominal tergite wholly smooth and shining. This ant is probably endemic from southern Bahia in Brazil. It was collected in a forest remnant of Tropical Mountain Rainforests in the Atlantic Forest biome.
