54279 Cathorops aguadulce (Meek, 1904) Ariidae Sea catfishes Ariinae Siluriformes Teleostei Estuarine sea catfish Central America: Atlantic draining rivers from Panuco River basin in Mexico to Izabal Lake in Guatemala (Ref. 58032). Materials examined from río Usumacinta and lago Izabal basins, formerly treated as <i>Cathorops aguadulce</i> (e.g. Castro-Aguirre et al., 1999; Miller et al., 2005; Betancur-R. and Willink, 2007), are treated as <i>Cathorops kailolae</i>(Ref. 75004). Examination of more materials is needed to determine whether the population reported from other localities reported by Miller et al., 2005 from other localities (i.e. río Panuco, río Tecolutla, río Coatzacoalcos, and Gulf of Mexico) should be separated (Ref. 75004).
