In this paper, Freeman and Lynch conduct a thorough examination of Allophryne ruthveni, analyzing its morphological characteristics, geographical distribution, and genetic relationships with other members of the family Leptodactylidae. The authors aim to clarify the taxonomic status of this species within the broader context of South American amphibians.The study includes detailed descriptions of the frog's physical features, such as size, coloration, and distinct anatomical traits that differentiate it from closely related species. Freeman and Lynch utilize various specimens collected from different regions to provide a comprehensive overview of the species' variability.
