Hemitriakis japanica (Müller & Henle, 1839)
Type locality: Japan.
The five Taiwanese samples of H. japanica included in this analysis formed a single cluster that included previously collected samples of this species from Taiwan, Japan and Vietnam (Supplementary Material 1; Naylor et al., 2012a). This cluster is closely related and sister to the H. leucoperiptera clade consisting of samples from the Philippines (Supplementary Material 1).
