外文摘要：Phylogenetic relationships of intra- and interspecies were elucidated based on complete cytochrome b (cyt b) and cytochrome c oxidase subunit II (COII) gene sequences from 12 recognized species of genus Lutjanus Bloch in the South China Sea (SCS). Using the combined data set of consensus cyt b and COII gene sequences, interspecific relationships for all 12 recognized species in SCS were consistent with Allen's morphology-based identifications, with strong correlation between the molecular and morphological characteristics. Monophyly of eight species (L. malabaricus, L. russellii, L. stellatus, L. bohar, L. johnii, L. sebae, L. fulvus, and L. fulviflamma) was strongly supported; however, the pairs L. vitta/L. ophuysenii and L. erythropterus/L. argentimaculatus were more similar than expected We inferred that L. malabaricus exists in SCS, and the introgression caused by hybridization is the reason for the unexpectedly high homogeneity.
