Natural Parasitism in Acromyrmex landolti Forel (Hymenoptera, Formicidae) in Pastures of Bahia, Brazil

This study aimed to evaluate the occurrence of natural parasitism in Acromyrmex landolti Forel, identify parasitoids associated to the species and to estimate parasitism rates. The experiment was conducted from January to May 2012 in Itapetinga, BA. 20 nests were excavated, removing eggs, larvae, pupae and adults for counting and evaluating parasitism, isolating adult parasitoids and parasitized ant larvae. Parasitism by Mimopria sp. (Diapriidae: Diapriini) occurred in nine nests, with an average rate of 12% of parasitized larvae. It is the first record of parasitism of Mimopria Holmgren in an Attini species

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

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
