Abstract

Amphimerus bragai n.sp. (Digenea, Opisthorchiidae) from the bile
ducts of a rodent from the State of Minas Gerais, Brazil, Nectomysn
squamipes (Cricetidae), is described. The new species was studied by
both light and scanning electron microscopy. A table is presented comparing
the measurements of the new species with those of A. lancea
(Diesing, 1850) and A. vallecaucensis Thatcher, 1970, parasites
of dolphins and marsupials, respectively. The new species is similar in
size and body form to A. vallecaucensis from which it differs in
having a vitellarium that extends to the acetabulum while that of the
former species are limited to the posterior one-third of the body.
Additionally, the new species is from a rodent.
