As a part of an ongoing biodiversity survey of aseptate gregarine fauna of oligochaete hosts of West Bengal, an expedition was carried out in the Darjeeling district of West Bengal and most of the earthworms collected were found to be infested with a species of Monocystis Stein, 1848. The monocystid species was collected from the seminal vesicles of the earthworm and was identified as a new species, Monocystis amynthae sp. nov. The gamont of the new species is characterized by having an elongated body with broad anterior end, separated from the narrow posterior end by a prominent constriction measuring 49.0-77.0 (66.0+/-1.3) microm x 32.0-41.0 (37.0+/-2.8) microm. The gametocysts are oval-shaped, measuring 40.0-65.0 (58.0+/-2.1) microm. The oocysts are navicular, measuring 8.0-12.0 (10.5+/-1.1) microm x 4.0-6.0 (5.5+/-1.1) microm.
作为西孟加拉邦寡毛纲宿主的无隔簇虫动物群正在进行的生物多样性调查的一部分，在西孟加拉邦大吉岭地区开展了一次考察，发现所采集的大多数蚯蚓都感染了一种1848年斯坦因发现的单房簇虫属物种。该单房簇虫物种是从蚯蚓的精囊中采集的，并被鉴定为一个新物种，即阿米恩单房簇虫（Monocystis amynthae sp. nov.）。新物种的配子体特征为身体细长，前端宽阔，与狭窄的后端由一个明显的缢缩分开，缢缩大小为49.0 - 77.0（66.0±1.3）微米×32.0 - 41.0（37.0±2.8）微米。配子囊呈椭圆形，大小为40.0 - 65.0（58.0±2.1）微米。卵囊呈舟形，大小为8.0 - 12.0（10.5±1.1）微米×4.0 - 6.0（5.5±1.1）微米。
