Distribution extension and first verified records for Narrow-bridged Musk Turtle, Claudius angustatus Cope, 1865 (Testudines, Kinosternidae) in the Selva Lacandona, Mexico.

We document the first verifiable records of Claudius angustatus Cope, 1865 in the Selva Lacandona, Chiapas, Mexico. Three individuals were observed in different types of anthropic land covers. These records are the most recent observations of C. angustatus in the southeastern zone of its range in more than 20 years, thus representing the southernmost known occurrences of this species. With these records we confirm the long-suspected presence of C. angustatus in the region, increasing the number of reptile species in the Selva Lacandona to 91. [ABSTRACT FROM AUTHOR]
