Abstract: The Oosternum convexum species group is defined on the basis of ex- ternal morphological characters. Three species are recognized within the group, all of them endemic to the Cordillera de Talamanca Mts. in Central America: O. convexum sp. nov. (Panama, Costa Rica), O. intermedium sp. nov. (Costa Rica) and O. simplex sp. nov. (Costa Rica). A key to species is provided, along with drawings and SEM photographs of diagnostic characters.
Key words: Coleoptera, Hydrophilidae, Sphaeridiinae, Megasternini, Oosternum, new species, taxonomy, endemism, Neotropical Region, Central America, Cor- dillera de Talamanca
