Abstract

HERNANDEZ-ORDONEZ, Omar et al. First record of the limestone rainfrog Craugastor psephosypharus (Amphibia: Anura: Craugastoridae) in Mexico. Rev. Mex. Biodiv. [online]. 2017, vol.88, n.1, pp.260-264. ISSN 2007-8706.  https://doi.org/10.1016/j.rmb.2017.01.005.

We document the first record of Craugastor psephosypharus (Craugastoridae) for Mexico. In October 2014, we collected 2 individuals of this species and observed another 8 specimens in a tropical moist forest fragment in the Lacandona region, southeastern Mexico. We found the frogs during daytime in the rainy season, in the vicinity of a small karst cave system. This new record extends the known distribution of the species 75 km to the west, near the Guatemala–Mexico border. We measured air temperature and vegetation structure at the study site. Air temperatures inside karst cavities were 0.5 °C lower than outside. This is the westernmost record of the species. The finding increases the number of known amphibian species in Mexico to 378.

Keywords : Craugastor psephosypharus; Lacandona region; Warty forest frog.
