Metadelphis tkachi n. sp. is described based on material from the gall-bladder of Molossus molossus (Pallas) (Chiroptera: Molossidae) in the Brazilian eastern Amazon. The main differentiating characters of the new species include lobed, tandem testes and elongated clusters of vitelline follicles commencing at the level of the seminal receptacle. The new species can be distinguished from Metadelphis lenti (Santos & Gibson, 1998) and Metadelphis apharyngotrema (Marshall & Miller, 1979) by the shape and position of the testes; from Metadelphis evandroi Travassos, 1944 by having tandem, lobed testes and shorter clusters of vitelline follicles; from Metadelphis compactus Travassos, 1955 by having tandem testes and more elongated clusters of vitelline follicles, and from Metadelphis alverangai Travassos, 1955 by having smaller testes and body, and vitellarium with large follicles. New morphological data are reported for M. lenti based on light and scanning electron microscopy; intraspecific variation was observed.
基于巴西东部亚马逊地区皱唇犬吻蝠（Pallas）（翼手目：犬吻蝠科）胆囊中的材料，描述了新物种特氏后阴吸虫（Metadelphis tkachi n. sp.）。新物种的主要鉴别特征包括叶状、前后排列的睾丸以及始于受精囊水平的细长卵黄滤泡簇。新物种可通过睾丸的形状和位置与缓殖后阴吸虫（Metadelphis lenti）（Santos & Gibson，1998年）和无咽后阴吸虫（Metadelphis apharyngotrema）（Marshall & Miller，1979年）区分开来；通过具有前后排列的叶状睾丸和较短的卵黄滤泡簇与埃氏后阴吸虫（Metadelphis evandroi）（Travassos，1944年）区分开来；通过具有前后排列的睾丸和更细长的卵黄滤泡簇与紧密后阴吸虫（Metadelphis compactus）（Travassos，1955年）区分开来，以及通过具有较小的睾丸和身体以及带有大滤泡的卵黄腺与阿尔氏后阴吸虫（Metadelphis alverangai）（Travassos，1955年）区分开来。基于光学显微镜和扫描电子显微镜，报道了缓殖后阴吸虫的新形态学数据；观察到种内变异。
