Three new species of the genus Harpagopalpus are described from Madagascar, allowing a redefinition of diagnostic character states of the monotypic family Harpagopalpidae, previously known only from Western Africa (two species) and India (one species. The separation of the subgenera Harpagopalpus and Harpagopalpellus is supported by new characters. Harpagopalpus octoporus K.Viets, 1924 and H. tetraporus K.Viets, 1924 are redescribed and a lectotype is designated of H. octoporus. A fourth new species is described from Cameroon, based on a male specimen erroneously considered to be the female of H. octoporus by K. Viets.
