Nicholsina usta (Valenciennes, 1840)


Nicholsina usta (Valenciennes, 1840) 

UFESAbout UFES 160 (1 specimen) from the fish market in São Tomé City. Encountered over a dense growth of Caulerpa  sp. near Ilhéu das Cabras in about 10 m depth ( SMNSAbout SMNS 25233, 1 specimen). The eastern Atlantic Nicholsina usta  are generally considered to form the subspecies N. usta collettei Schultz, 1968  . Two animals from São Tomé analysed by Robertson et al. (2006) were genetically distinct from four western Atlantic animals to such a degree that the authors suggested the recognition of the two subspecies as valid species.
