坦噶尼喀湖是东非中部大裂谷的一个湖泊，以慈鲷和其他一些动物群体的高度特有性而闻名（Coulter，1991; Fryer，1991）。单型慈鲷属Haplotaxodon Boulenger，1906，也是该湖特有的，与该湖的其他慈鲷属非常不同的是拥有一个向上指向的嘴和一排锥形牙齿在颌骨上（Boulenger，1906; Regan，1920; Poll，1986）。在对坦噶尼喀湖进行的一系列科学调查中，在湖中的不同地点收集了一种未描述的单齿龙标本（图1）。
LAKE Tanganyika, one of the Great Rift Valley lakes in central east Africa, is famous for the high levels of endemism among the cichlid fishes and some other animal groups (Coulter, 1991; Fryer, 1991). The monotypic cichlid genus Haplotaxodon Boulenger, 1906, also endemic to the lake, is quite distinct from other cichlid genera of the lake by the possession of a mouth which is directed upward and a single row of conical teeth on the jaws (Boulenger, 1906; Regan, 1920; Poll, 1986). During a series of scientific surveys of Lake Tanganyika, specimens of an undescribed species of Haplotaxodon were collected at various localities in the lake (Fig. 1).
