Description

aqua - International Journal of Ichthyology Volume 12, Issue

Revision of the Genus Symphysodon Hechel, 1840 (Teleostei: Perciformes: Cichlidae) based on molecular and morphological characters by Heiko Bleher, Kai N. Stolting, Walter Salzburger, and Axel Meyer.

Abstract:
Systematics of the cichlid genus Symphysodon has been investigated and three species are recognised: S. discus Heckel, 1840 (synonym: S. discus willischwartzi Burgess, 1981); S. aequifasciatus Pellegrin, 1904 (synonyms: S. discus var. aequifasciata Pellegrin, 1904; S. aequifasciata aequifasciata sensu Schultz, 1960; S. Discus Tarzoo � sic � Lyons, 1960); and S. haraldi, Schultz, 1960 (synonyms: S. aequifasciata haraldi Schultz, 1960; S. aequifasciata axelrodi Schultz, 1960). The present revision is based on DNA sequences of partial mitochondrial control regions of 48 specimens of Symphysodon from 20 different locations in the central and lower Amazon basin, which revealed three genetically distinct clades of Symphysodon. One of these genetic clusters is composed of specimens that morphologically are S. discus, but also of S. haraldi and natural hybrids of S. discus x S. haraldi. This indicates that either the �discus� clade is composed, at least partially, of hybrids or, alternatively, that a �haraldi� phenotype evolved (or was retained) independently in this clade. The other two clades consist of S. aequifasciatus and S. haraldi. The definition of the three species is supported by extensive field studies over the last 40 years, investigating distributional patterns and documenting adaptation of each species to a distinct type of water, characterised by unique chemical parameters. In addition, S. discus and S. aequifasciatus display distinct colorations and colour patterns, with nine vertical bars on each flank. In S. discus the first, and particularly the fifth and ninth bars are prominent and/or wider, while all bars are typically of equal width in S. aequifasciatus. The latter species is also recognised by its rust-brown or red dots on the body, ranging from a few spots to a dense cover all over, rarely forming red spotted lines or being present in the anal fin region only. Symphysodon haraldi displays a wide range of colours, colour patterns and a larger number of vertical bars (8 up to 16), which may differ substantially in shape. Except for hybrids of S. discus x S. haraldi, S. haraldi does not resemble the other two species. A study of geographic distribution patterns of the three species was carried out throughout the central and lower Amazon basin: in the western Amazon in almost every tributary of the Solim�es and the Mara�on Rivers to Iquitos, and in the eastern part in most tributaries of the Amazon River down to its mouth. The valid names of the three species are: S. discus � the Heckel discus; S. aequifasciatus � the green discus; and S. haraldi � the blue discus. The �brown� or �common� discus of the aquarium trade is the same as the �blue� discus. In S. aequifasciatus a congruence of genetic and morphological (colour) characters has been found, whereas some specimens that would phenotypically be assigned to S. haraldi, genetically group also with the S. discus clade. Only future studies using nuclear DNA markers will allow untangling the evolutionary history of the phenotypcially heterogeneous S. �discus� clade.
