Amphimerus bragai n.sp. (Digenea: Opisthorchiidae), a parasite of the rodent Nectomys squamipes (Cricetidae) from Minas Gerais, Brazil

Amphimerus bragai n.sp. (Digenea, Opisthorchiidae) from the bile ducts of a rodent from the State of Minas Gerais, Brazil, Nectomys 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 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.
