摘要
We describe a new species of anguid lizard of the genus Mesaspis from the Sierra de los Cuchumatanes of northwestern Guatemala. This species reaches a maximum snout-vent length of about 72 mm, making it much smaller than Mesaspis moreletii. In the Sierra de los Cuchumatanes it occurs sympatrically with Mesaspis moreletii temporalis, the only such instance of congeneric sympatry known in Nuclear Central America. The new species appears most similar to the widely distributed species M. moreletii, whichmay be polytypic. Mesaspis cuchumatanus may be distinguished from M. moreletii by usually having expanded supranasals, 16 longitudinal scale rows, small and granular scales covering the side of the neck from about the level of upper edge of auricular opening to ventrolateral fold, and smaller body size.
