Pseudopecoelus sosoae sp. nov. and P. sewelli (Digenea, Opecoelidae) from the deep-sea fish Neoscombrops pacificus (Perciformes, Acropomatidae) off New Caledonia

  • Rodney A. Bray
  • Jean-Lou Justine


Pseudopecoelus sosoae sp. nov. and P. sewelli Bray, 1990 are described from the rare fish Neoscombrops pacificus from the deep-sea (about 200–400 m) off Nouméa, New Caledonia, the southernmost report of this fish species. A visual key based on 12 characters is presented, which shows that P. sosoae is distinguished from the most similar species (P. vulgaris, P. elongatus, P. priacanthi, P. akamachi and P. sphyraenae) by its very large eggs, elongate body and unlobed gonads. P. sewelli has a similar shape, but much smaller eggs and lobed gonads.


Digenea Opecoelidae Pseudopecoelus sosoae sp. nov. P. sewelli deep-sea fish Neoscombrops pacificus New Caledonia 


Pseudopecoelus sosoae sp. nov. et P. sewelli Bray, 1990 sont décrits du poisson rare Neoscombrops pacificus pêché en mer profonde au large de Nouméa, Nouvelle-Calédonie, la mention la plus au Sud de cette espèce. Une clé visuelle basée sur 12 caractères est présentée, et montre que P. sosoae se distingue par ses oeufs très grands, son corps allongé et ses gonades non lobées. P. sewelli a une forme similaire, mais des oeufs plus petits et des gonades lobées.
