First records of Agamyxis pectinifrons (Cope, 1870) (Siluriformes, Doradidae) from the state of Chiapas, Mexico, and an extension of the geographic range in the Grijalva river basin

Abstract

We provide the first records of occurrence of Spotted Raphael Catfish, Agamyxis pectinifrons, in Chiapas, Mexico, and extend the geographic range of this species in the Grijalva river basin. We collected 42 specimens, for which we present morphological and meristic data from 28 of these. The larger number of individuals and the range of sizes recorded suggest that A. pectinifrons is established in this region of the Grijalva basin.
