TAXONOMIC STUDY OF 2 PROTEOCEPHALUS SPECIES (CESTODA, PROTEOCEPHALIDAE) PARASITIZING COREGONID FISHES - THE SYNONYMY OF P-FALLAX LA RUE, 1911 WITH P-EXIGUUS LA RUE, 1911
T. Scholz et V. Hanzelova, TAXONOMIC STUDY OF 2 PROTEOCEPHALUS SPECIES (CESTODA, PROTEOCEPHALIDAE) PARASITIZING COREGONID FISHES - THE SYNONYMY OF P-FALLAX LA RUE, 1911 WITH P-EXIGUUS LA RUE, 1911, Systematic parasitology, 27(1), 1994, pp. 1-12
Type-specimens (syntypes) and comparative material of two Proteocephal
us species, P. exiguus La Rue, 1911 and P. fallax La Rue, 1911, parasi
tic in coregonid fishes from the Holarctic Region, were evaluated taxo
nomically. Morphological and biometrical study revealed conspecificity
of the taxa. P. fallax is therefore, considered to be a synonym of P.
exiguus. Supplementary information is added to the species diagnosis
of P. exiguus and a lectotype is designated herein.
