Abstract. We report the northernmost Atlantic Coast record of the Cloudy Snail Sucker (Sibon nebulatus) from the state of Hidalgo, at a straight-line distance of about 185-km from the nearest historical locality in Sierra Norte de Puebla, Mexico. We assess the potential distribution of this species and compare morphological characteristics of specimens from Mexico and Central America. No significant morphometric or meristic differences were found. A species distribution model suggests that S. nebulatus is widely distributed on both coasts of Mexico, with a high probability of occurrence at a wider range of latitudes than current records indicate.
