摘要
Based on morphometric and allozyme data of a large sample of black-chinned tilapia, Sarotherodon melanotheron, originating from over its entire geographical distribution range, the subspecific classification of this species has been revised. One subspecies, S. m. paludinosus, is synonymized with S. m. hezldelotii. The validity of another subspecies, S. m. leonensis, is questioned. The remaining three subspecies, S. m. melanotheron, S. m. heudelotii and S. m. nigripinnis are clearly distinguished as separate taxa.
