Abstract
The genera Pycnadenoides Yamaguti, 1938 and Pseudopycnadena Saad-Fares & Maillard, 1986 are redefined and their validity discussed. Two forms, currently considered to be Pycnadenoides senegalensis Fischthal & Thomas, 1972, one from Lithognathus mormyrus and Diplodus vulgaris off Corsica (Scandola) and one from Sparus aurata off Provence and Languedoc, are described separately, as some preliminary biochemical studies suggest that they might be distinct. This species is commented upon in relation to Distomum mormyri Stossich, 1885, D. umbrinae Stossich, 1885, Pycnadenoides pagrosomi Yamaguti, 1938 and P. ghanensis Fischthal & Thomas, 1968. Pseudopycnadena fischthali Saad-Fares & Maillard, 1986 is redescribed from Diplodus vulgaris, D. annularis and D. sargus off Corsica (Scandola).
Résumé
Les auteurs redéfinissent et discutent la validité des genres Pycnadenoides Yamaguti, 1938 et Pseudopycnadena Saad-Fares & Maillard, 1986. Deux formes considérées actuellement comme Pycnadenoides senegalensis Fischthal & Thomas, 1972, l'une parasite de Lithognathus mormyrus et de Diplodus vulgaris des côtes de Corse (Scandola), l'autre parasite de Sparus aurata des côtes de Provence et du Languedoc, sont décrites séparément. Des études biochimiques préliminaires suggèrent qu'il pourrait s'agir de deux espèces différentes. Cette espèce est discutée par rapport à Distomum mormyri Stossich, 1885, D. umbrinae Stossich, 1885, Pycnadenoides pagrosomi Yamaguti, 1938 et P. ghanensis Fischthal & Thomas, 1968. Pseudopycnadena fischthali Saad-Fares & Maillard, 1986 est redécrit à partir d'exemplaires provenant de Diplodus vulgaris, D. annularis et D. sargus des côtes de Corse (Scandola).
