Galeus nipponensis Nakaya, 1975

Type locality: Mimase, off Kochi Prefecture, Honshu, Japan.

The single G. nipponensis sample included in this analysis is the first representative sample for this species and it formed a distinct lineage, sister to Parmaturus xaniurus from off California (GN1536) (Supplementary Material 1). As indicated in Naylor et al. (2012b), the genus Galeus may be paraphyletic and thus the generic placement of this species needs to be examined in the future.
