The foxface rabbitfish was first formally described as
Amphacanthus vulpinus in 1845 by the German zoologists
Hermann Schlegel &
Salomon Müller with the
type locality given as
Ternate Island one of the
Molucca Islands in Indonesia. The blotched foxface (
S. unimaculatus) differs from
S. vulpinus in possessing a large black spot below the soft-rayed part of the
dorsal fin. It is
sympatric and not
phylogenetically distinct, and though these two might be recently evolved species, they may be just colour
morphs and should arguably to be united under the scientific name
S. vulpinus. The
specific name vulpinus means "fox-like", Schlegel and Müller did not explain what this alluded to but it is thought to be the pointed snout. ==Description==
