Leptodactylus caatingae, a new species of frog from eastern Brazil (Amphibia: Anura: Leptodactylidae)

A new species of frog of the genus Leptodactylus is described from eastern Brazil. The new species differs little morphologically from L. latinasus, but the advertisement calls are very different. The geographic distribution of L. latinasus and the new species, together with the respective levels of differentiation of morphology and call, is mirrored in the species pair L. bufonius and L. troglodytes. Presumably the same historical event or events lead to differentiation of these species pairs.
