Systematics of the Genus <i>Eubothrium</i> Nybelin (Cestoda, Pseudophyllidea), with Partial Re‐description of the Species

Abstract

Material from as many species of the cestode genus Eubothrium as could be obtained (six out of nine existing species), from a range of hosts and from both marine and freshwater habitats, were examined both by light and scanning electron microscopy. The scolex shape as seen with SEM turned out to be a very valuable specific character. Particular attention was also paid to the possibility that intra‐specific races, distinguishable on biological criteria, might in addition exhibit characteristic morphological differences.
