Differs from other species of the genus by the shape of the postnodal telopodite, which resembles a thresher shark’s tail, and by the triangular shape of the sternal process on segment 6.

The name is a noun in apposition, referring to the thresher shark, Alopias vulpinus (Bonnaterre, 1788), and its tail in particular, the shape of which resembles the postnodal teleopodite in the new species.
