| Abstract: | A new species of hyperoliid frog, Heterixalus carbonei n.sp., is described from the Antsingy forest inwestern Madagascar. It is characterized by an advertisement call consisting of long and regular note series. The only other Heterixalus with a similar call structure, H. betsileo from higher altitudes in eastern Madagascar, has distinctly shorter notes. After recent discoveries of the occurrence of H. luteostriatus and H. tricolor in western Madagascar, the new species brings the number of Heterixalus known from western Madagascar to three. |
