Systematics of the tribe Trematocarini (Perciformes: Cichlidae) from Lake Tanganyika, Africa

 Phylogenetic relationships among eight Trematocara species and a single Telotrematocara species included in the Tanganyikan cichlid tribe Trematocarini were investigated on the basis of morphological features. The monophyly of the tribe is supported by the presence of hypertrophied sensory pores on the head, tendon “c” of adductor mandibulae section 1, a single scale row between the upper lateral line and body axis, great depth of the anteriormost infraorbital (reversed in Trematocara caparti and T. stigmaticum), and the absence of a lower lateral line. Trematocara is paraphyletic unless Telotrematocara is treated as a junior synonym. Received: December 10, 2001 / Revised: March 18, 2002 / Accepted: April 4, 2002
