Squalus brevirostris Tanaka, 1917

Type locality: Tokyo fish market, probably from Shimonoseki, Japan.

The three Taiwanese samples of S. brevirostris included in this analysis formed a single cluster that included two samples of S. brevirostris from Japan ( Figure 4). Until recently, this species was considered to be a junior synonym of S. megalops but molecular and morphological studies have shown this is a species complex. The S.

brevirostris clade is sister to the S. cf. megalops clade that includes samples from off South Africa and Angola ( Figure 4).
