Bathycreadium brayi n. sp. is described based on specimens collected from the deep-sea greater forkbeard Phycis blennoides (Brünnich) (Gadiformes: Phycidae) in the Western Mediterranean. The new species is distinguished from B. flexicolle Kabata, 1961, B. elongata (Maillard, 1970) and B. nanaflexicolle Dronen, Rubec & Underwood, 1977 by the much smaller size of the body and most organs, the large (in relation to body length and width) ventral sucker and the distinctly more anterior extent of the vitelline fields and from B. biscayense Bray, 1973 in having a narrower body, longer forebody and oesophagus, distinctly smaller ventral sucker and sucker width ratio and the shape of the gonads. Re-examination of the type-material of B. biscayense revealed that the original description of this species is based on composite material. A redescription of B. biscayense based on adult specimens from its type-host, Trachyrincus scabrus (Rafinesque), and new data based on the re-examination of the type-specimens of B. flexicolle and B. elongata are also provided.
