[Syncoelicotyloides macruri gen. et sp. n.--the first representative of the subfamily Syncoelidotylinae (Microcotylidae, Monogenea) from macruriform fishes].

Syncoelicotyloides macruri gen. et sp. nov., a monogenean of the subfamily Syncoelicotylinae Mamaev et Subtschenko, 1978, is described. Members of this subfamily were known only from Notacanthiformes and are found for the first time in Macrouriformes. This fact is considered by the authors as a confirmation of the earlier supposition (Mamaev, Zubtschenko, 1978) about phylogenetic closeness of these fishes.
