Abstract: The Madagascan material of the halobatine genus EurymetraEsaki, 1926 (Hemiptera:
Heteroptera: Gerridae: Halobatinae), which is deposited at the Natural History
Museum Vienna, is revised. A close examination of “Eurymetra madagascariensis
Poisson, 1945” revealed two new species, Eurymetra santamariae sp. nov.
andEurymetra papaceki sp. nov. A definition of the newly established Eurymetra
madagascariensis species group is provided as well as keys to the freshwater
halobatine genera and to Eurymetra species known from Madagascar.
