Abstract
Frogs of the Eleutherodactylus diastema group are found in the lowlands of western Colombia and are represented by six species. Ten species are recognized in this species group distributed from Nicaragua to Ecuador. Two of the species (E. chalceus and E. scolodiscus) are placed in a plesiomorphic subgroup whereas the other eight species of the group are placed in the diastema subgroup (including three species described as new, two from the northern part of the biogeographic Chocó and one from the eastern slopes of the Cordillera Central). As many as four species are found sympatrically in the northern lowlands of the Chocó (all separated neatly by differences in body size).
