Dipturus tengu (Jordan & Fowler, 1903)

Type locality: Matsushima Bay, Sendai, Japan.

The seven Taiwanese samples of D. tengu sequenced in this study formed a single cluster, sister to a specimen identified as Dipturus sp. 4 from the Philippines (GN4353) in Naylor et al. (2005b) (Supplementary Material 1). Interestingly they did not cluster with a specimen identified as D. tengu (GN1025), also from Taiwan in Naylor et al. (2005b). This could represent cryptic speciation within this species, but more samples of skates from Taiwanese waters will be required to resolve this issue.
