Abstract

A revision of the genus Macromalthinus resulted on recognition of twelve species, six of which are herein proposed as new: Macromalthinus belemensis Brancucci, 1981, M. brasiliensis (Pic, 1906), M. globuliventris Brancucci, 1981, M. guyanensis sp. nov., M. luteoapicalis sp. nov., M. maximiceps Pic, 1919, M. orapuensis sp. nov., M. piceiventris sp. nov., M. quadratithorax sp. nov., M. santaremensis Brancucci, 1981, M. schmidli Constantin, 2010 and M. xerophilus sp. nov. No taxonomic changes were necessary in the previously described species, which are distinguished through differential diagnosis and an updated identification key. The type specimens of all species were revisited and their photographs are provided. Discussions on the diagnostic character of each species, general morphology and the first description of wings and female genitalia of Macromalthinus are presented, as well as the first description of the female of M. maximiceps Pic, 1919. Finally, new records and distribution maps are presented for all species.
