Abstract

A rare intersexual form of the genus Fannia R.-D. is described. It was found among a large amount of specimens of the genus collected between 1963 and 2014 in the southernmost region of South America. A brief historical account of these specimens within the family Fanniidae is presented, as well as a thorough morphological description of external characters as well as the description and interpretation of the genitalia. A very brief discussion of the possible cause of this phenomenon is also included.
