Background and goal.

The translocation of the Barred Splitfin Chapalichthys encaustus (Goodeidae) in the Teuchitlán River, located at the headwaters of the Ameca river basin in the center of the state of Jalisco, is reported for the first time.

Methods.

The fish record was obtained approximately 1 km from the origin of the river. Fish were deposited in the ichthyology collection of the Universidad Michoacana de San Nicolás de Hidalgo (CPUM).

Results.

On July 17, 2015 an adult female specimen of this species with a total length of 65 mm was collected. The specimen is described and illustrated. In subsequent collections a male specimen of the same species was also obtained.

Conclusion.

The Barred Splitfin is one of the few documented cases of native translocated ichthyofauna for Mexico and its possible impact on the Teuchitlán River has not been determined.
