Molecular Phylogeny and Genetic Differentiation of the Tanakia himantegus Complex (Teleostei: Cyprinidae) in Taiwan and China

phylogeny and genetic differentiation of the Tanakia himantegus complex (Teleostei: Cyprinidae) in Taiwan and China. Zoological Studies 48(6): 823-834. Tanakia himantegus himantegus is a subspecies endemic to Taiwan (referred as the Taiwanese himantegus), while T. himantegus chii is distributed in both Taiwan (referred as the Taiwanese chii) and China (referred as the Chinese chii). We analyzed the complete cytochrome (Cyt) b DNA sequences of 61 specimens of the T. himantegus complex (including the Taiwanese chii, Chinese chii, and Taiwanese himantegus) to infer their phylogeny, genetic differentiation, and historical demography. Both Bayesian and maximum-likelihood trees showed that the Taiwanese chii, Chinese chii, and Taiwanese himantegus are 3 monophyletic groups. Among them, the Taiwanese chii clustered with the Chinese chii. The average pairwise genetic distance (HKY + G) between the Taiwanese chii and Chinese chii was 6.8%
