Madapolystoma ramilijaonae n. sp. and Madapolystoma cryptica n. sp. (Monogenea, Polystomatidae) are described from the urinary bladder of disjunct populations of the Madagascar shrub frog Guibemantis liber. Although only minor morphological characters distinguish the new species from the single nominal species of the genus, i.e. Madapolystoma biritika, their strong and concordant differentiation in a mitochondrial and a nuclear gene supplemented by phylogenetic analyses indicates that M. ramilijaonae n. sp. and M. cryptica n. sp. should be regarded as two distinct species. Because anuran polystomes are known to be host-specific, the description of two cryptic species from a single host species points to a taxonomic complex situation in G. liber, a widespread frog that is characterized by the presence of several deep conspecific lineages and possibly by hybridization and admixture with other species of Guibemantis.
新物种马达加斯加多盘虫（Madapolystoma ramilijaonae n. sp.）和隐秘多盘虫（Madapolystoma cryptica n. sp.）（单殖吸虫纲，多盘科）是从马达加斯加灌木蛙（Guibemantis liber）分散种群的膀胱中发现的。尽管新物种与该属唯一的命名物种即比氏多盘虫（Madapolystoma biritika）仅在微小形态特征上存在差异，但它们在线粒体和核基因上的强烈且一致的分化，再加上系统发育分析表明，马达加斯加多盘虫新物种和隐秘多盘虫新物种应被视为两个不同的物种。由于已知无尾两栖类多盘虫具有宿主特异性，从单一宿主物种中描述出两个隐秘物种，这表明在马达加斯加灌木蛙中存在分类学复杂的情况，这种分布广泛的蛙类的特征是存在几个深度分化的同物种谱系，并且可能与吉氏蛙属的其他物种发生杂交和混合。
