Hypotheses of the relationships among the nominal species in the subfamily Delphininae. (sensu LeDuc [3]) based on A. recent morphological analyses [26,27,102-104,108,109,115] (none included Sousa chinensis), B. full mtDNA cytb sequences [3,21,24,25] in which Delphinus capensis was found to be nested within D. delphis, and C. a combined analysis of 2 mtDNA sequence loci and 10 nuclear gene sequence loci [20] (in which an additional genus, Sotalia, is hypothesized to belong to the subfamily).
