The genus Mahea Distant, 1909 (Heteroptera: Pentatomoidea: Acanthosomatidae: Acanthosomatinae) is revised. Muschalea Cachan, 1952, is corroborated as a junior synonym of Mahea. Five species are recognized: Mahea sexualis Distant, 1909, (Seychelles) and M. andriai (Cachan, 1952) (Madagascar) are redescribed based on examination of the type specimens; three additional species – Mahea distanti sp. nov., M. durrelli sp. nov., and M. parvula sp. nov. from Madagascar – are described. The lectotypes of M. sexualis and Noualhieridia rufa Cachan, 1952, are designated. A key to the known acanthosomatid species of Madagascar and Seychelles is given. Possible phylogenetic relationships among the genera Mahea, Catadipson Breddin, 1903, Ibocoris Roche, 1948, and Uhlunga Distant, 1892, are briefly discussed.
