Amphibian species of the family Hylidae exhibit a high degree of endemism in Mexico. To better understand ongoing declines of many amphibian populations, especially for endemic species that are particularly vulnerable to extinction, information on diverse aspects of their biological makeup is required, including their ecology. This study provides an analysis of the distribution, natural history, feeding habits, reproduction, morphology, and conservation status of Charadrahyla taeniopus, a species endemic to central Mexico. The distribution of this species extends along the Sierra Madre Oriental, primarily in cloud forest. Based on changes in climatic niche, decreases of 14.14% and 37% of its distributional range are predicted to occur by the years 2050 and 2070, respectively. An examination of the stomach contents from 31 adults and two juveniles revealed plant materials and arthropods as major parts of their diet. Charadrahyla taeniopus is sexually dimorphic in size. Females were larger than males, and after correcting for body size, females had larger jaws than males. Based on guidelines proposed by national legislation (NOM-059), we propose that this species should continue to be classifed as Threatened. Further studies are necessary to classify it in a high conservation category by international legislation (IUCN) guidelines, due to the high vulnerability indicated by the Environmental Vulnerability Score, which is caused by an accelerated loss of habitat.
