Abstract: | Aphyosemion schmitti can be separated from neighbouring species on the basis of colour pattern, crossing experiments, cytogenetics, genetics and zoogeographical distribution. Three groups of Aphyosemion can be distinguished, based on morphological and meristic characters, colour patterns and geographical distribution; i.e. the liberiense group, the guineense group and the occidentalis group. A differentiation of the Liberian Aphyosemion is proposed, and its possible phylogenetic relationships are discussed. |
