(William Edward) Descriptions of Two Species of Frogs, Genus Ptychohyla Studies of American Hylid Frogs, V Produced by Chris Curnow, Joseph Cooper, Diane Monico, and the Online Distributed Proofreading Team at https://www.pgdp.net "Descriptions of Two Species of Frogs, Genus Ptychohyla" by William Edward Duellman is a scientific publication written in the early 1960s. This work is part of the "Studies of American Hylid Frogs" series and focuses on two newly identified species of frogs within the genus Ptychohyla. The book details the findings of field studies conducted in southern Mexico and northern Central America, particularly highlighting the previously underrepresented specimens of this genus. In this publication, Duellman introduces two new species: Ptychohyla ignicolor and Ptychohyla chamulae, derived from extensive field research in the cloud forests of Oaxaca and Chiapas, respectively. The text provides a thorough description of each species, including their physical characteristics, habitat preferences, and acoustic signaling patterns. The paper also contains detailed polytypic comparisons to other known species, illustrating the distinctiveness of these new frogs based on morphological and behavioral attributes. By documenting these species, Duellman's work contributes valuable insights into the biodiversity of hylid frogs and emphasizes the ecological significance of their natural habitats.
