Description
Summary:Gyrodactylus longidactylus n. sp., a gyrodactylid monogenean parasitising the gills of Pomatoschistus lozanoi (de Buen, 1923) in the North Sea is described. It is a species with rather small anchors which are only connected to a ventral bar which lacks a ventral bar membrane. The marginal hooks have long handles, which are always longer than the total length of the anchor. The pharynx has long pharyngeal processes. Measurements, drawings of the opisthaptoral hard parts, penis and pharynx, and SEM micrographs of this monogenean are presented. G. longidactylus n. sp. is the first monogenean species described from P. lozanoi. status: published
