Hymenoptera, Formicidae Latreille, 1809: New records for Atlantic Forest in the state of Rio de Janeiro.

Standardized sample design helped to increase our knowledge on the ant fauna of Brazilian biomes, in particularleaf litter ants of Atlantic Forest. In this study are presented the new records of nine ant species for the state of Rio deJaneiro: Amblyopone armigera Mayr, 1897, A. elongata (Santschi, 1912), Prionopelta punctulata Mayr, 1866, Lachnomyrmexplaumanni Borgmeier, 1957, Trachymyrmex iheringi (Emery, 1887), Pachycondyla arhuaca Forel, 1901, P. stigma (Fabricius,1804), Thaumatomyrmex mutilatus Mayr 1887 and Proceratium brasiliense Borgmeier, 1959.
