Abstract

The gyrodactylid monogenean Gyrodactylus syngnathi n. sp. is described from specimens infesting the head, body and fins of the pipefish Syngnathus rostellatus Nilsson, 1855 in the Oslo Fjord, Norway. It is a small species of the metanephrotid type, with a large pharynx bearing long pharyngeal processes. The penis has 8–11 small spines in one row. The opisthaptor is distinguished by having a small ventral bar lacking processes, but with a minute, triangular ventral bar membrane. This is the second description of a Gyrodactylus species from a syngnathid. The relationship of G. syngnathi to other members of the genus is unclear.
