Abstract
A new species of Proteocephalid cestode, Crepidobothrium eirasi n. sp. is described from Phractocephalus hemioliopterus (Schneider, 1801), a freshwater siluriform fish from the Amazon. This is the first report of Crepidobothrium in fish. The other known species are parasites of S outh American snakes. Crepidobothrium eirasi n. sp. is characterized m ainly by their small size (with only 7-12 segments), by the notched, h eart-shaped suckers, by the posterior ventral appendix of the proglott is, by the vitelline follicles, located between and external to the lo ngitudinal muscle fibres (paramuscular), and by the absence of vitella ria in the preporal region of proglottis.
