ResumoA new species of Abronia is described from the cloud forest of Cerro Bauil, Oaxaca, M6xico. The closest relative of this species appears to be A. reidi of the Sierra de los Tuxtlas in southern Veracruz. The discovery of this species provides additional evidence of past faunal inter- change of cloud forest species across the Isthmus of Tehuantepec. The lowlands of the Isthmus region have been considered to be one of the major barriers to the dispersal of highland faunas in Middle America. Nevertheless, examples of species or closely related species displaying a disjunct pattern of distribution on either side of the Isthmus are relatively numerous. The various regions that share portions of their herpetofaunas with the southeastern Oaxacan highlands appear to be in order of similarity, the highlands of northern Chiapas, the Pacific highlands of Nuclear Central America including the Sierra Madre de Chiapas and southern volcanic highlands of Guatemala, the Sierra de los Tuxtlas, and the northern Oaxacan highlands including the Sierra Juasrez and
