Abstract: 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.
