A survey to know the diversity of endoparasitic protozoan parasites of the earthworms of West Bengal, revealed a new species of the genus Stein, 1848, that resides in the seminal vesicle of the earthworm Perrier. sp. nov. is characterized by ovoidal gamonts (trophozoites) with inconspicuous mucron and measure 69.53-102.25 (86.29 ± 11.48) μm × 24.54-61.35 (35.17 ± 12.82) μm. Shape of the gametocysts are almost rounded and measure 81.80-110.43 (96.11 ± 8.85) μm in diameter. Oocysts are navicular with pointed ends and measure 11.55-12.32 (11.78 ± 0.36) µm × 5.00-5.77 (5.39 ± 0.25) µm.
一项旨在了解西孟加拉邦蚯蚓体内寄生原生动物寄生虫多样性的调查，发现了1848年斯坦属的一个新物种，该物种寄生于Perrier蚯蚓的精囊中。新物种的特征为卵形配子体（滋养体），具不明显的短尾，大小为69.53 - 102.25（86.29 ± 11.48）μm × 24.54 - 61.35（35.17 ± 12.82）μm。配子囊形状几乎呈圆形，直径为81.80 - 110.43（96.11 ± 8.85）μm。卵囊呈舟形，两端尖，大小为11.55 - 12.32（11.78 ± 0.36）μm × 5.00 - 5.77（5.39 ± 0.25）μm。
