Phylogenetic interrelationships of 32 species belonging to 18 genera and four families of the superfamily Microphalloidea were studied using partial sequences of nuclear lsrDNA analysed by Bayesian inference and maximum parsimony. The resulting trees were well resolved at most nodes and demonstrated that the Microphalloidea, as represented by the present data-set, consists of three main clades corresponding to the families Lecithodendriidae, Microphallidae and Pleurogenidae + Prosthogonimidae. Interrelationships of taxa within each clade are considered; as a result of analysis of molecular and morphological data, Floridatrema Kinsella & Deblock, 1994 is synonymised with Maritrema Nicoll, 1907, Candidotrema Dollfus, 1951 with Pleurogenes Looss, 1896, and Schistogonimus Lühe, 1909 with Prosthogonimus Lühe, 1899. The taxonomic value of some morphological features, used traditionally for the differentiation of genera within the Lecithodendriidae and Prosthogonimidae, is reconsidered. Previous systematic schemes are discussed from the viewpoint of present results, and perspectives of future studies are outlined.
利用贝叶斯推断和最大简约法分析的核小核糖体DNA部分序列，研究了微杯科18个属、4个科的32个物种的系统发育关系。得到的树在大多数节点上都得到了很好的解析，表明以本数据集为代表的微杯科由三个主要分支组成，分别对应于枝腺科、微杯科和侧殖科+前殖科。考虑了每个分支内分类单元的相互关系；通过对分子和形态学数据的分析，1994年的佛罗里达吸虫属（Floridatrema Kinsella & Deblock）与1907年的海生吸虫属（Maritrema Nicoll）同义，1951年的透明吸虫属（Candidotrema Dollfus）与1896年的侧殖吸虫属（Pleurogenes Looss）同义，1909年的裂睾吸虫属（Schistogonimus Lühe）与1899年的前殖吸虫属（Prosthogonimus Lühe）同义。重新考虑了一些传统上用于区分枝腺科和前殖科内属的形态特征的分类价值。从当前结果的角度讨论了以前的系统发育方案，并概述了未来研究的前景。
