Abstract
A survey to know the diversity of endoparasitic protozoan parasites of the earthworms of West Bengal, revealed a new species of the genus Monocystis Stein, 1848, that resides in the seminal vesicle of the earthworm Perionyx excavatus Perrier. Monocystis kuidongae 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.
