The synonymy of Proteocephalus neglectus La Rue, 1911 with P. exiguus La Rue, 1911, two fish cestodes from the Holarctic Region (original) (raw)

Abstract

Two cestode species of the genus Proteocephalus Weinland, 1858, P. neglectus La Rue, 1911, parasitic in salmonid fishes, and P. exiguus La Rue, 1911, occurring mostly in coregonids, were evaluated taxonomically. Comparison of the morphology and morphometry revealed that the taxa apparently represent morphological forms of one polymorphic species, for which the name Proteocephalus exiguus La Rue, 1911 is proposed. A redescription of this species, based on extensive comparative material from different fish hosts and geographical areas, is given. The reliability of criteria (size of the body and shape of segments, characteristics relating to the head morphology, presence/absence of microtriches on the scolex surface, relative size of the cirrus-sac, number of testes and testicular layers, shape of genital atrium, size of the egg) used previously for differentiating these species is also discussed.
