A biodiversity survey of aseptate gregarines in earthworm hosts in the Calcutta district of West Bengal State revealed the existence of a new species of aseptate gregarine under the genus Monocystis Stein, 1848. The monocystid gregarines obtained from the earthworm host, Eutyphoeus quaripapillatus Michelsen, 1907 have been identified as a new species. The mucron was indistinct. The gamonts are elongated, ovoid, have a hood like structure at the anterior end and measure 150.1-212.4 (188.1+/-2.1) micromx66.1-112.1 (72.3+/-1.1) microm. The gametocysts are ellipsoid and measure 92.3-136.3 microm (111.2+/-2.1)x78.3-114.4 microm (82.6+/-3.6) microm. Prominent syzygy was apparent. Oocysts are navicular, measuring 14.1-22.3 (18.1+/-3.2) micromx9.1-15.2 (11.9+/-1.1) microm.
对西孟加拉邦加尔各答地区蚯蚓宿主中无隔簇虫的生物多样性调查显示，存在一种隶属于1848年斯坦因（Stein）建立的单房簇虫属（Monocystis）的新无隔簇虫物种。从蚯蚓宿主——1907年米克尔森（Michelsen）命名的四乳头真蚓（Eutyphoeus quaripapillatus）中获得的单房簇虫已被鉴定为一个新物种。其尾刺不明显。配子体细长呈卵形，前端有帽状结构，大小为150.1 - 212.4（188.1±2.1）微米×66.1 - 112.1（72.3±1.1）微米。配子囊呈椭圆形，大小为92.3 - 136.3微米（111.2±2.1）×78.3 - 114.4微米（82.6±3.6）微米。明显可见显著的配对现象。卵囊呈舟形，大小为14.1 - 22.3（18.1±3.2）微米×9.1 - 15.2（11.9±1.1）微米。
