Genera of Leptodactylid Frogs in México

The paper revises the classification of Mexican and northern Central American leptodactylid frogs, surveying prior taxonomic treatments and recent synonymies, and argues that eleutherodactyline frogs are best divided into four genera rather than three. Through comparative analysis of integumentary glands, hand and foot morphology, terminal phalange shape, tarsal structures, and select osteological features, the author redefines generic limits, recognizes an additional genus, and discusses implications for phylogenetic relationships and zoogeographic distribution across Middle America.
