Hydrolagus mitsukurii (Jordan & Snyder, 1904)

Type locality: Japan.

The four specimens identified as Hydrolagus mitsukurii formed a distinct clade sister to the only other chimaeroid species included in this analysis, Chimaera phantasma (Supplementary Material 1). These four Taiwanese samples represent the centre of the known distribution of this species, which extends from Japan to the Philippines.
