La existencia de anomalías en anfibios se ha documentado en todo el mundo. Una anomalía morfológica se define como cualquier desviación del rango normal de variación anatómica, que puede ser causada por mutaciones, fallas en el desarrollo embrionario o trauma. En México, la información científica publicada sobre anomalías morfológicas en anfibios ha sido reciente y en la mayoría se trata de casos aislados observados en campo. Aquí presentamos el primer reporte de anoftalmia en Bolitoglossa platydactyla y un caso de exceso de piel en Rheohyla miotympanum. Así como, una lista actualizada de los casos de anomalías morfológicas en anfibios mexicanos.

The Cuban Brown Anole (Anolis sagrei) is native to the Bahamas, the Cuba Archipelago, and Little Cayman, but is now among the world’s most widely distributed invasive lizards. In Mexico, the species has been reported from the states of Campeche, Chiapas, Jalisco, Quintana Roo, Tabasco, Tamaulipas, Veracruz, and Yucatán. However, no complete compendium exists summarizing the locality-level distribution of A. sagrei in Mexico. Herein we provide an exhaustive compilation of vouchered Mexican specimens based on museum records and the literature. Supplementing this review are reports of five new localities for A. sagrei in Veracruz and Tabasco. We conclude with brief comments on the potential ecological effects of this species in Mexico.

Distributional and natural history notes for Bromeliohyla dendroscarta (Anura: Hylidae) in Veracruz, Mexico. Two new locality records are reported for the critically endangered hylid frog, Bromeliohyla dendroscarta, in Veracruz, Mexico. The frogs were found in semideciduous tropical forest, an ecotone of semideciduous tropical forest and mountain cloud forest, and an agricultural mosaic; none of these habitats has been documented previously for this species. Information is provided on larval feeding habits, duration of larval development under natural conditions and external morphology of tadpoles.
