Hypleurochilus pseudoaequipinnis


Hypleurochilus pseudoaequipinnis  ZBK  Bath, 1994

SMNS 24224 (1 specimen, Bom Bom Islet) and SMNS 24131 (1 specimen, Bom Bom Islet). UFES 141 (1 specimen, Santana Islet). Afonso et al. (1999) recorded this species as Hypleurochilus aequipinnis  Günther, 1861, based on an underwater observation by PW. H. aequipinnis  and H. pseudoaequipinnis  ZBK  are sister species in the eastern and the western Atlantic, respectively. Surprisingly, the three SMNS and UFES specimens from São Tomé and Príncipe correspond to the western Atlantic pseudoaequipinnis  ZBK  and not the eastern Atlantic aequipinnis  in the shape of the supraorbital tentacles and the colour of the head, as described by Bath (1994). Comparative material: H. aequipinnis  : SMNS 16660, Senegal; H. pseudaequipinnis  : SMNS 19384, Netherlands Antilles.
