6. Cyrtolophosis muscicola Stokes, 1885 ( Figure 2 A-C)

Diagnosis of the Indian population (Data based on 5 specimens): Size about 20 × 10 μm in protargol preparations; shape ovoid, oral aperture with a prominent shallow groove occupying the anterior third of the cell. Nuclear apparatus composed of one spherical and centrally positioned macronuclear nodule and one or two micronuclei attached to macronuclear nodule. About 15 kinety rows, anterior tuft of cilia present.

Material deposited: One slide including protargol-impregnated specimens have been deposited at the National Zoological Collections of the Zoological Survey of India, Kolkata, India with the following accession numbers Pt. 4012/2 (11 specimens) .

Occurrence and ecology: Cyrtolophosis muscicola has a cosmopolitan distribution, it has been reported from five biogeographic regions, i.e., Holarctis, Palaeotropis, Australis, Neotropis, and Archinotis. The present study reports its presence from soil sample collected from the Flamingo Bird Sanctuary (19°06’40’’N 72°59’49’’E). The sampling site was having a small ponds, grassland, trees and mangrove. It feeds mainly on bacteria.
