Occurrence and variability of Crenicichla saxatilis (Linnaeus, 1758) in Surinam, and restriction of its typelocality (Pisces, Perciformes, Cichlidae)

The South American cichlid species Crenicichla saxatilis (Linnaeus, 1758) is redescribed and figured. The variability of colour pattern, and raeristic and morphometric characters are recorded, based on examination of hundreds of specimens from Surinam, including the lectotype. The morphometric characters are tested on validity and discussed. The distribution of C. saxatilis in Surinam is delimited, and the type-locality is restricted to Carolina ( = Malasie) Creek, Suriname River system. Remarks on the status of Crenicichla saxatilis albopunctata Pellegrin, 1904, and of Crenicichla alta Eigenmann, 1912, are included.
