| Popis: | Nematocystis indicus sp. nov. (Figs. 1���4) Gamont Length (GL) 172.0���400.0 ��m (257.0�� 65.0 ��m); Gamont Width (GW) 18.0���49.0 ��m (25.0�� 9.0 ��m); Nucleus Length (NL) 18.0���26.0 ��m (20.0�� 3.3 ��m); Nucleus Width (NW) 9.0���11.0 ��m (9.5 �� 0.8 ��m); Gametocyst Diameter (GD) 48.0���68.0 ��m (56.0�� 1.3 ��m); Oocyst Length (OL) 7.0��� 11.5 ��m (9.3 �� 1.1 ��m). Gamonts are elongated, with a cylindrical main body and a short wider anterior portion which contains the small nucleus. Both the ends are gradually narrowed like a ���V��� to a nearly pointed tip. The anterior one��third of the cell is approximately two times wider than the posterior portion. Body length varies from 172.0���400.0 ��m (257.0�� 65.0 ��m). The maximum body width ranges from 18.0���49.0 ��m (25.0�� 9.0 ��m) while the average body width ranges from 5.5 ���11.0 ��m (7.0�� 1.5 ��m). Ectoplasm is thin, hyaline, about 1.0���2.0 ��m wide. The width of ectoplasm is greatest at the anterior tip where it is 5.0���6.0 ��m in thickness. At the posterior end the thickness of the ectoplasm is 1.5 ���2.0 ��m. Endoplasm is finely granular. Within the endoplasm very small spindle��shaped paraglycogen reserve granules of about 1.0 ��m by 0.5 ��m size have been observed. Nucleus is small, slightly elongate, measuring 18.0���26.0 x 9.0���11.0 ��m, having karyosome diffused throughout the nucleoplasm, enclosed within a nuclear membrane. Gametocyst almost rounded with two almost equal gametocytes. Dimension of the gametocyst ranges from 48.0���68.0 ��m (56.0�� 1.3 ��m). Oocysts biconical, measuring 7.0��� 11.5 ��m (9.3 �� 11.0 ��m). Taxonomic summary Type Host: Perionyx excavatus (Perrier) Location of the parasite: Seminal vesicles of the host. Type Locality: Sandeshkhali, South 24 Parganas, West Bengal, India Symbiotype: Host PE 03��� 16 / 11 / 2004 deposited in the museum of the Department of Zoology, University of Kalyani, Kalyani 741235, West Bengal, India. Type specimens: Syntypes on the slides no. NI/04, NI/ 12 and NI/ 14 are deposited in the Museum of the Zoological Survey of India, Kolkata�� 700016 (Registration no. 2901, 2903, 2904). Etymology: The species Nematocystis indicus sp. nov. has been named after our motherland, India.
