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