Phylogenomic, morphological and acoustic data support a revised taxonomy of the lissodelphinine dolphin subfamily

The dolphin genus Lagenorhynchus has included six species of dolphins characterized by short, wide rostra. Genetic analyses have consistently found the genus to be polyphyletic with four of the species being included in the subfamily Lissodelphininae. A recent paper synthesized available molecular, morphological and acoustic evidence to support a taxonomic revision of the genus, assigning L. obliquidens, L. obscurus, L. australis and L. cruciger to the genus Sagmatias within Lissodelphiniae. Here, we add new phylogenomic data to a previously analyzed dataset including over 3000 nuclear genes and complete mitochondrial genomes and reevaluate morphological and acoustic evidence for the phylogenetic relationships among the Lissodelphininae. We find strong molecular evidence that L. australis and L. cruciger are more closely related to the four members of the genus Cephalorhynchus than they are to L. obliquidens&nbsp..., , , # Data from: Phylogenomic, morphological and acoustic data support a revised taxonomy of the lissodelphinine dolphin subfamily
