title: Massaliatrema misgurni n. sp. (Trematoda: Heterophyidae) whose metacercariae encyst in loaches (Misgurnus anguillicaudatus).
abstract: Hitherto unknown metacercariae were found encysted in loaches (Misgurnus anguillicaudatus) from China. They were experimentally fed to golden hamsters, and gravid adults were recovered 1 week post-infection from their small intestines. A new species, Massaliatrema misgurni n. sp. (Heterophyidae), is described from the adults. This new species is different from M. gyrinicola Dollfus and Timon-David, 1960, in having a smaller acetabulum/oral sucker ratio, less branched vitellaria widely entering the intercecal anteroacetabular area and an almost median seminal receptacle; and from M. yamashitai Kamiya and Ohbayashi, 1975, in having a larger acetabulum/oral sucker ratio, with the seminal vesicle situated in the uterine loop and the vitellaria entering the intercecal anteroacetabular area. This report is the first record of M. anguillicaudatus as a second intermediate host of the genus Massaliatrema Dollfus and Timon-David, 1960.
