Between January 2011 and March 2011 occurrence of trichodinid ciliophorans were studied in the freshwater fishes of the river Churni. The biodiversity survey revealed presence of a new species of the genus Trichodina (Ehrenberg 1830) infesting Glossogobius giuris (Hamilton-Buchanan). Another freshwater fish Labeo bata (Hamilton 1822) were found to be(More)
Two new species of the genus Trichodina Ehrenberg, 1838, T. silondiata sp. nov. and T. pangasi sp. nov. from the gills of freshwater fish Silonia silondia (Hamilton 1822) and Pangasius pangasius (Hamilton-Buchanan) respectively from the river Ganges of West Bengal are described here. Wet smears of gills and skins were prepared in the field, air dried and(More)
A survey aimed at exploring the endoparasitic acephaline gregarine diversity in South-western Bengal, detected a new species of the genus Monocystis Stein, 1848, that resides in the seminal vesicles of the earthworm, Apporectodea trapezoides Duges collected in the district of Bankura from alluvial soil. Monocystis apporectodae sp. nov. is a ribbon-like(More)
Biodiversity studies in search of endoparasitic acephaline gregarines revealed a new species of the genus Monocystis Stein, 1848 in the seminal vesicles of the earthworm Metaphire houlleti (Perrier) residing in alluvial soil of the district of North 24 Parganas. The new species is characterized by having bean-shaped gamonts measuring 94.0-151.0(More)
A new species of Henneguya parasitizing tissues affected by the ulcerative disease syndrome of a freshwater fish Anabas testudineus (Bloch) from Khiodum and Pumlen lakes of Manipur state is described. Of the fishes examined 75% were found to be infested with this myxozoan parasite. Mature spores of the new species are elongated, biconvex, and oval with(More)
A comprehensive icthyoparasotological survey among estuarine and freshwater fishes of West Bengal, India revealed Trichodinella sunderbanensis sp. nov. and Trichodina acuta Lom, 1961 from an estuarine fish Mystus gulio (Hamilton, 1822) from the Vidyadhari river; Trichodina nandusi sp. nov. from a freshwater fish, Nandus nandus (Hamilton-Buchanan);(More)
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(More)
In a survey of the endoparasitic acephaline gregarines in the Satkhira district of Bangladesh, seminal vesicles of earthworm, Metaphire posthuma were found to be infested with a new species of the genus Enterocystis Tsvetcov 1926, Enterocystis elongatum sp. nov. The new species is elongated and measures 55.3-87.8 (67.7 ± 10.3) μm in length and 33.2-37.8(More)
During the course of surveys of endoparasitic aseptate gregarines in Darjeeling district of West Bengal, India, seminal vesicles of Amynthas hawayanus (Rosa 1891) found to be infested with a new species of the genus Apolocystis (Cognetti de Martiis 1923). Trophozoites are spherical or rounded and without any polar differentiation. Diameter of the(More)
As a part of an ongoing biodiversity survey of aseptate gregarine fauna of oligochaete hosts of West Bengal, an expedition was carried out in the Darjeeling district of West Bengal and most of the earthworms collected were found to be infested with a species of Monocystis Stein, 1848. The monocystid species was collected from the seminal vesicles of the(More)
