Five new species of the genus Petrotilapia from Lake Malawi, Africa.
Ichthyol. Explor. Freshwaters 22: 149-168.
Most rocky shores of Lake Malawi harbor three different members of Petrotilapia, each one occurring in its own
preferred habitat. None of the known species of Petrotilapia has a lake-wide distribution and similar habitats at
separate localities harbor sometimes different species. The relationship between the members of each of the three
groups is not only reflected in the habitat preference but often also in the basic melanin pattern. The three species
groups have been referred to as the P. tridentiger group, the P. nigra group and the P. genalutea group. Five new
species from various habitats throughout the lake are described: P. xanthos, P. flaviventris (both P. nigra group),
P. palingnathos (P. tridentiger group), P. pyroscelos (P. genalutea group), and P. mumboensis which is the only species
that cannot satisfactorily be assigned to any of these groups.
