Nannocharax maculicauda, a new species of African characoid fish (Characoidea: Distichodontidae) with comments on the genus Hemigrammocharax



Proceedings of the Biological Society of Washington 944: 1076-1084



ISSN/ISBN: 0006-324X

A new species of African characoid of the genus Nannocharax is described from the upper Ivino River system of Gabon. The high longitudinal scale count, elongate body form and absence of marked head and body pigmentation other than a prominent caudal peduncle spot distinguish this species within the monophyletic assemblage formed by Nannocharax and Hemigrammocharax within the Distichodontidae. The validity of the currently used diagnostic character for Hemigrammocharax is discussed.
