Descriptions of Two Species of Frogs, Genus Ptychohyla / Studies of American Hylid Frogs, V

Field studies in cloud forests and adjacent regions present taxonomic descriptions of two previously undescribed species of Ptychohyla and a reassessment of groupings within the genus. The paper separates species into two groups based on presence or absence of horny nuptial spines, tarsal folds, call structure, and tadpole lip morphology, then provides formal diagnoses, detailed measurements, coloration in life and alcohol, and morphological characters for holotypes and paratypes. Comparisons with related species, notes on habitat and behavior, and brief natural-history observations accompany the descriptions, while broader osteological, acoustic, and phylogenetic analyses are deferred to a forthcoming comprehensive review.
