A new species of Furcohaptor Bijukumar & Kearn, 1996 (Monogenea: Diplectanidae) parasitic on Cynoglossus robustus Günther (Pleuronectiformes: Cynoglossidae) in the Seto Inland Sea, Japan, with comments on its systematic position and an amended generic diagnosis of Furcohaptor.

ABSTRACT

Furcohaptor brevis n. sp. is described from the gills of Cynoglossus robustus Günther caught in the Seto Inland Sea off Hiroshima Prefecture, Japan. Although Furcohaptor Bijukumar & Kearn, 1996 has been assigned to the Ancyrocephalinae Bychowsky, 1937 in the Dactylogyridae Bychowsky, 1933, this genus is transferred to the Diplectaninae Monticelli, 1903 in the Diplectanidae Monticelli, 1903 based on both morphological and molecular data. An amended generic diagnosis is provided.
