RESUMO
All species of Macrostomus Wiedemann allied with Macrostomus pictipennis (Bezzi), are treated in the pictipennis species-group. Three currently recognized species and four new species are included, namely M. cervicicauda Smith, M. cysticercus Smith, M. manauara, sp. nov. from Brazil (Amazonas and Pará states), M. pacaraima, sp. nov. from Brazil (Roraima, Amazonas and Pará states), M. pictipennis (Bezzi), M. smithi, sp. nov. from Guyana and Brazil (Roraima State) and M. utinga, sp. nov. from Brazil (Pará State). All primary types were examined and a key to species is presented.

RESUMO
The two species described in the genus Axelempis Curran, 1931, junior synonym of Macrostomus Wiedemann, 1817, Axelempis fulvithorax Curran, 1931 and A. fasciventris Curran, 1931 are redescribed from the types. The first one remains in the genus Macrostomus and the second one is transferred to Porphyrochroa Melander, 1928, here revalidated.
