We would like to thank the Ethiopian Wildlife Conservation Authority and the Ethiopian Biodiversity Institute for providing us with collecting and export permits for the samples. We are very grateful to Yann Bourgeois, Marcin Falis, Yejie Yun, and Paula Mora Rojas who helped with the acoustic recordings in the field. Fieldwork in Ethiopia would not have been possible if not for the invaluable assistance of Megersa Kelbessa, Itbarek, and Samuel Woldeyes of Rock Hewn Tours. This work could not have been possible without the assistance of many curators and collection managers from numer-ous institutions, including Bezawork Afework Bogale and M. Ketema, Natural History Collection, Addis Ababa University, Ethiopia; Jeff Streicher, The Natural History Mu-seum, London; Andreas Schmitz, Museum d’Histoire Naturelle, Geneva; and Mark-Oliver Rödel and Frank Tillack, Museum für Naturkunde Berlin. We thank Yann Bourgeois and Sebastian Kirchhof who helped with measuring specimens and Marcin Falis and Kole Utzinger who helped with lab work. We are in debt with Marc Ar-noux and Nizar Drou from the Genome Core Facility and the Bioinformatics group at NYUAD. Finally, we thank the subject editor and the two reviewers for their valuable comments which helped improving this manuscript. The NYUAD Sequencing Core is supported by NYUAD Research Institute grant G1205A to the NYUAD Center for Genomics and Systems Biology. This research was supported by New York University Abu Dhabi Research Funds AD180 (to SB).

N2 - Frogs of the genus Ptychadena that inhabit the Ethiopian highlands serve as a model system to understand biogeography, diversification, and adaptations to high elevations. Despite recent studies focusing on the systematics of this group, the taxonomy of the Ptychadena neumanni species complex remains only par-tially resolved, owing largely to the morphological resemblance of its members. Here, the taxonomy of this historically problematic group of frogs is revised by integrating morphological and molecular analyses on both century-old type specimens and more recently collected material. Based on these multiple lines of evidence, the P. neumanni species complex is shown to be more speciose than previously thought and four new species are described. With the aim of clarifying and stabilizing the taxonomy of the group, six species are also re-described and morphological and acoustic identification keys are provided. This study also establishes species distribution maps and reveals important differences in range size between the members of the P. neumanni complex, calling for adapted conservation measures across the Ethiopian highlands.
