Thalassoma newtoni  ( Osório, 1891)

SMNS 23066 (1 specimen) São Tomé City; SMNS 23131 (3 specimens) Rolas Island; SMNS 24878 (20 specimens) Rolas Island. UFES 172 (12 specimens) Praia Quinze, near Lagoa Azul, São Tomé. For a long time, T. newtoni  was treated as a junior synonym of T. pavo  (Linnaeus, 1758). Afonso et al. (1999) also used the name T. pavo  but noted that the color pattern of animals from São Tomé island was distinctly different (Figure 14). In a genetic comparison of the Atlantic species of the genus Thalassoma  , Costagliola et al. (2004) noted a large genetic divergence between specimens from São Tomé and Mediterranean specimens of T. pavo  ; furthermore, the species T. ascensionis  and T. sanctaehelenae  were more closely related to animals from São Tomé than these were to T. pavo  . Thus, T. newtoni  appears to be a valid species but a morphological comparison with T. pavo  is still outstanding. Juveniles of this species were frequently observed cleaning other fish.
