چکیده
The genus Zygocystis Stein 1848 comprises acepha line gregarines with pyriform gamonts, always found in frontal syzygy, and navicular oocysts. Levine (1988) listed 14 species in this genus and 3 more species have been added since (Segun, 1978; Pradhan and Dasgupta, 1983, Bandyopadhyay and Mitra, 2004). Two of them, Zygocystis indicus Pradhan and Dasgupta 1983 and Z. levinei Bandyopadhyay and Mitra 2004, have been reported from Indian earthworms. The present paper contains the description of yet another Indian Zygocystis species obtained from the earthworm Perionyx graveleyi in West Bengal.
