Not quite all the haplochromines in Lake Malawi
are endemic to the lake, having evolved within it and found only there;
only almost all of them! Three exceptional, widely distributed
species are listed below. One of them, the Pseudocrenilabrus, has
only recently been alleged to occur in
Lake Malawi, but I know of no evidence that it actually does. (Click on the genus and
species to go to the page for that fish, or click the author and year
to go to the bibliographic citation for the original scientific description of the species.)
