摘要

研究人员从俄罗斯远东地区南部两个地方的 Pseudaspius hakonensis 鱼肠中发现了新的吸虫，并获得了新的形态学和分子数据。从形态上看，这些吸虫与日本的 Pseudozoogonoides ugui（微球纲：Zoogonidae）相同。根据基于 28S rDNA 序列数据的系统进化分析结果，P. ugui 与 Zoogonoides viviparus 关系密切，而 P. subaequiporus 则是这两个物种的姊妹类群。根据 28S rDNA 和 ITS2 rDNA 计算的 P. ugui 与 Z. viviparus 之间的遗传距离值代表了种间分化水平。我们的结果具有模棱两可的解释，这表明应重新考虑存在一个或两个紧密的玻璃体聚集体对 Zoogonoides 和 Pseudozoogonoides 的区分的影响，或者我们的结果开启了以前表示为 Z. viviparus 和 P. subaequiporus 的吸虫的分类地位问题。

Morphological and molecular data on Pseudozoogonoides ugui Shimazu, 1974 (Digenea: Microphalloidea: Zoogonidae) ex Pseudaspius hakonensis (Günther, 1877) and taxonomic problems in Zoogoninae genera.

New morphological and molecular data were generated for trematodes recovered from the intestines of the fish Pseudaspius hakonensis from two locations in the south of the Russian Far East. Morphologically, these trematodes are identical to Pseudozoogonoides ugui (Microphalloidea: Zoogonidae) from Japan. According to results of phylogenetic analysis based on 28S rDNA sequence data, P. ugui was closely related to Zoogonoides viviparus, and P. subaequiporus appears as a sister taxon to these two species. Genetic distance values, calculated based on both 28S rDNA and ITS2 rDNA, between P. ugui and Z. viviparus represents an interspecific differentiation level. Our results have an ambiguous explanation, indicating that the implication of the presence of one or two compact vitellarial aggregations for the differentiation of Zoogonoides and Pseudozoogonoides should be reconsidered or that our results open up the question of the taxonomical status of trematodes previously denoted as Z. viviparus and P. subaequiporus.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
