Abstract
Comparison of freshly collected tetraphyllidean cestodes from a teleost fish, Alepisaurus ferox Lowe, from 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 a shark, Prionace glauca (Linnaeus), from the Indian Ocean between Réunion and Madagascar, revealed their conspecificity. Consequently, P. bipartitus is considered a junior synonym of P. speciosum and the genus Prionacestus Mete & Euzet, 1996 is suppressed. The life-cycle of the parasite, which retains larval features and is considered to represent a neotenic form, is discussed.
