Abstract

<abstract abstract-type="author" id="ab0005"> <title id="st0005">Abstract</title> <sec> <p id="sp0005">Adult <italic>Astiotrema odhneri</italic> Bhalerao, 1936 sensu Cho &amp; Seo 1977 were found in the intestine of a freshwater turtle, <italic>Pelodiscus sinensis</italic> (Wiegmann), from the Komissarovka River Basin, Primorsky Region, Russia. It was established that the first intermediate host of this parasite is a snail, <italic>Anisus centrifugops</italic>, and that the second intermediate hosts include the snails, <italic>Helicorbis sujfunensis</italic> and <italic>A. centrifugops</italic>, tadpoles of the frog <italic>Rana dybowskii</italic>, and the fish <italic>Perccottus glenii</italic>. The development of <italic>A</italic>. <italic>odhneri</italic> includes the formation of sporocyst and xiphidiocercariae, which is typical for species belonging to Plagiorchioidea. Phylogenetic analysis based on 28S rRNA gene sequences showed that <italic>A. odhneri</italic>, together with <italic>Astiotrema monticellii</italic>, form a monophyletic clade that was closer to Opisthorchioidea than to any other taxon represented in the tree. However, phylogenetic analysis without outgroup taxon indicated a high degree of differentiation of <italic>Astiotrema</italic> from both Plagiorchioidea and Opisthorchioidea.</p> </sec> </abstract>
