Biodiversity studies in search of endoparasitic acephaline gregarines revealed a new species under the genus Nematocystis Hesse, 1909. The species has been obtained from the seminal vesicles of the earthworm, Eutyphoeus nicholsoni (Beddard). Gamonts of this species are solitary and bear a perfect nematoid appearance with smoothly curved terminals, especially in mature forms. Mature gamonts measure 245.40-302.66 (270.68±18.86) μm in length and 20.45-26.58 (24.54±2.10) μm in width. Nucleus is rounded or slightly ovoidal, 20.45-24.54 (22.69±1.74) μm in diameter. Gametocysts are almost rounded, measuring 77.71-85.89 (82.82±2.69) μm in diameter. Oocysts are navicular, measuring 7.70-8.47 (8.24±0.36) μm x 4.23-4.62 (4.50 ±0.18) μm.
