Mating flight seasonality in the Genus labidus (Hymenoptera : Formicidae) at Minas Gerais, in the Brazilian Atlantic Forest Biome, and Labidus nero, junior synonym of Labidus mars

摘要

This study examines a series of records made on mating flight activity of species of the Labidus genus in a forest reserve at Vicosa, Minas Gerais State, Brazil, in the dominium of the Atlantic Forest. Due to an exhaustive sampling effort over 18 years, the males of three species of Labidus were collected at light traps: Labidus coecus, Labidus nero and Labidus praedator, showing that they are the only three species of Labidus existent in the locality. The occurrence of the males of L. nero, as well as two records of L. mars workers were recently made in the same place, let us conclude that Labidus nero (Santschi 1930) is in fact a junior synonym of Labidus mars (Forel 1912).
