Molecular evidence for clear speciation of Tachysurus adiposalis complex in northern and central Taiwan

Abstract

Tachysurus adiposalis (Oshima, 1919) belongs to the bagrid catfish genus Tachysurus in Taiwan. To understand the phylogenetic status of this species, this study was planned to use the ND2 gene and D-loop sequences. A total of 14 samples were used in phylogenetic reconstruction under both method of Neighbor-Joining and Maximum-Likelihood. In the molecular phylogenetic tree shows good results in distinguishing each single haplotype for its own represented species. By this study, which indicates that the Tachysurus adiposalis from Nothern Taiwan are the sister clade of the Tachysurus sp.1 from the Central Taiwan with specific mitogenetic distance for further explorations.
