Taxonomic status of Pelichnibothrium speciosum Monticelli, 1889 (Cestoda: Tetraphyllidea), a mysterious parasite of Alepisaurus ferox Lowe (Teleostei: Alepisauridae) and Prionace glauca (L.) (Euselachii: Carcharinidae)


, : Taxonomic status of Pelichnibothrium speciosum Monticelli, 1889 (Cestoda: Tetraphyllidea), a mysterious parasite of Alepisaurus ferox Lowe (Teleostei: Alepisauridae) and Prionace glauca (L.) (Euselachii: Carcharinidae). Systematic Parasitology. September; 411: 1-8

Comparison of freshly collected tetraphyllidean cestodes from the teleost fish Alepisaurus ferox, collected in 1997 from Shimizu, Japan, with types and vouchers of Pelichnibothrium speciosum Monticelli, 1889, described from the same host, and specimens of Prionacestus bipartitus Mete & Euzet, 1996, from the spiral valve of the shark Prionace glauca from the Indian Ocean between Reunion and Madagascar, revealed their conspecificity. Consequently, Prionacestus bipartitus is considered a junior synonym of Pelichnibothrium speciosum and the genus Prionacestus Mete & Euzet, 1996 is suppressed. An amended description of Pelichnibothrium speciosum is presented, with illustrations. The life-cycle of the parasite, which retains larval features and is considered to represent a neotenic form, is discussed; it is thought that Prionace glauca is the definitive host and A. ferox is either the second intermediate host or a paratenic host.

Adults may feed within the subarctic waters reaching as far nort...
