Atlantic Forest limita con Argentina, asi que puede afirmarse que tambien estan presentes, al menos en Misiones y Corrientes."We describe a species of the exclusively Neotropical dorylomorph ant genus
Leptanilloides (Leptanilloidinae), Leptanilloides atlantica sp. nov., based on
workers collected in the Atlantic Forest, São Paulo, south-eastern Brazil. The
11 species of Leptanilloides described are known from relatively high altitudes in
western America (from the Andes foothills in Bolivia to SierraMorena inMexico).
The discovery of a Leptanilloides species in south-eastern Brazil represents a
significant range extension for the genus; this new species shares characters with
Leptanilloides biconstricta (Bolivia), Leptanilloides femoralis (Venezuela) and
Leptanilloides gracilis (Mexico) and may be distinguished based on a combination
of traits."
