The life cycle and developmental stages of the trematode Neodiplostomum oriolinum Oschmarin, 1963 are described. It was experimentally established that under natural conditions of Primorye Region, the first intermediate hosts of this trematode are snails Polypylis semiglobosa, Helicorbis sujfunensis, and the second are tadpoles of Rana dybowskii. Adult worms were developed in chicken and rat. Based on comparative morphological analysis of adult worms developed under experimental conditions and data given in P. G. Oshmarin (1963) paper it is assumed that N. oriolinum and N. paraoriolinum Oschmarin, 1963 are synonyms.
