FBname: Nautla cichlid
Remark: Implied identification of material in ZMB collected with the holotype, suggests that <i>H. deppii</i> is valid, according to Stawikowski & Werner (1998:333). The status of <i>Heros montezuma</i> is uncertain, pending examination of the holotype.
Comments: Fast-flowing river over stony bottom, or slower stream, with pH 7.4, dGH 5, KH 6, 26C.
