T. Scholz et al., THE TAXONOMIC STATUS OF PROTEOCEPHALUS-DUBIUS LARUE, 1911 (CESTODA, PROTEOCEPHALIDAE), A PUZZLING PARASITE OF PERCH (PERCA-FLUVIATILIS L), Parasite, 2(2), 1995, pp. 231-234
The taxonomic status of the Fish cestode Proteocephalus dubius to Rue,
1911, a rare parasite of perch (Perca fluviatilis), is discussed on t
he basis of morphological and isoenzyme analyses. The results reveal t
hat P. dubius represents only an infrequent morphological Form of P. p
ercae characterized by a smell, rounded and shallow apical organ, elon
gate and/or rectangular proglottides and relatively long cirrus-sac re
aching io the mid-line of the proglottis.
