We describe a new dicrocoeliid collected from the Eurasian water shrew Neomys fodiens in Bulgaria based on the combination of morphological characteristics and molecular data.
Pojmanskatrema balcanica n. sp., n. gen. is distinguished from all other species of family Dicrocoeliidae Looss, 1900 in having a postovarian vitellarium situated in the posterior half of the body, postacetabular, nearly tandem, lobed testes, and relatively short body.
Molecular phylogenetic analysis based on 28S rDNA sequences of the new species and previously sequenced dicrocoeliid taxa has demonstrated close relationship of Pojmanskatrema n. gen. with the genus Eurytrema. Considering the non-monophyletic nature of previously recognized dicrocoeliid sub-families we support the recently proposed dissolution of the sub-families within this family.
我们基于形态特征和分子数据的结合，描述了一种从保加利亚的欧亚水鼩（Neomys fodiens）中采集到的新双腔吸虫。
巴尔干波伊曼斯吸虫（Pojmanskatrema balcanica），新属新种，与1900年卢斯（Looss）所定双腔科（Dicrocoeliidae）的所有其他物种不同，其卵巢后卵黄腺位于虫体后半部，在腹吸盘后方，睾丸近前后排列，分叶，且虫体相对较短。
基于新物种和先前测序的双腔吸虫类群的28S rDNA序列进行的分子系统发育分析表明，波伊曼斯属（Pojmanskatrema）新属与阔盘属（Eurytrema）关系密切。考虑到先前认可的双腔吸虫亚科的非单系性质，我们支持最近提议的该科内亚科的解体。
