Macrouridophora halargyrea n. sp. (Monogenea: Diclidophoridae) from Halargyreus johnsonii (Moridae) in the North-eastern Atlantic

Abstract

Macrouridophora halargyrea n. sp. (Monogenea: Diclidophoridae) is described from the gills of the morid teleost Halargyreus johnsonii caught off the Faroe Islands in the North-eastern Atlantic. This new species is differentiated from ten other species in the genus Macrouridophora Rubec & Dronen, in press, by its: specialised heart-shaped haptor distinctly set-off from the body proper; inverted orientation of the first three anterior pairs of clamps; distinct spinulation covering the isthmus and haptor; small body size; small numbers of testes; and host.
