Abstract
The characters originally used to define the monotypic genus Micro ananteris Lourenco, 2003 are reanalyzed from the point of view of their usefulness to justify its recognition as a genus apart from Ananteris Thorell, 1891. A study of pectinal morphology conducted with Scanning Electron Microscopy (SEM) in six species of Ananteris, along with the results presented by Lourenco (2003) and other authors, demonstrate that both genera cannot be separated based on the shape of the peg sensillae but demonstrate this character's (and the presence of seta-like structures) immediate usefulness at the species level instead. Such analysis of the morphological attributes of Microananteris as defined by Lourenco (2003) reveals there is no evidence in support of its validity. Therefore, Microananteris is synonymized with Ananteris and Microananteris minor Lourenco, 2003 transferred to this genus. A new species of Ananteris is also described from the Natural Reserve Palmari in the Brazilian Amazon.
