Pseudotriakis microdon de Brito Capello, 1868

Type locality: Setubal, Portugal, Northeastern Atlantic.

The five Taiwanese samples of P. microdon included in this analysis formed a single cluster, distinct from, but sister to, the P. microdon samples from the southern Madagascar Ridge and the Mid-Atlantic Ridge ( Figure 7). These results challenge the currently accepted view that this species is circumglobal in distribution (e.g. Compagno et al., 2005) and suggest that the western North Pacific population is distinct from the Northern Atlantic/ southwestern Indian populations. A taxonomic revision of this genus is required to determine whether these two clades represent distinct species and if so, determine whether Pseudotriakis acrales Jordan & Snyder 1904 described from Suruga Bay in Japan should be resurrected as a valid species.
