Abstract

Cercariae of two trematode species from the family Notocotylidae were found in the snailsandSexually mature flukes were obtained by experimentally infecting a duckling and a few chickens, respectively, with metacercariae from the found cercariae. Based on a combination of morphological and molecular (nuclear and mitochondrial markers) evidence, the trematodes grown in the duckling were identified asThe adult flukes obtained from the infected chickens were assigned to trematodes previously grouped into the genuson the basis of morphological characteristics, including the structure of tegumental papillae. However, according to molecular data, the found trematodes were differentiated at the generic level from other Notocotylidae. Based on the above evidence, we here erect a genus,n. g., to accommodate the type speciesn. g. n. sp.
