Species: Macrelmis aeolis , M. alea , M. browni sp. nov. and M. itatiaiensis sp. nov. Distribution ( Fig. 6 ): Brasil : Santa Catarina ( Hinton 1946 ), Rio de Janeiro (present work) and Minas Gerais (present work). History of the group : Macrelmis alea and M. aeolis were considered as closely related by Hinton (1946) based on the presence of spongy structure, presence of head granulation and shape of fifth abdominal sternite, but a species group has never been formally proposed. In addition to these two species, M. itatiaiensis sp. nov. and M. browni sp. nov. also have the defining characters and are added to the group.
