The Valley is surrounded by mountain ranges and has a diverse topography with a mosaic of varied habitats that have remained isolated from extraneous influences. The present report describes urostyloid ciliates from diverse ecozones within the core zone of the National Park. Six species of the urostyloids, including Anteholosticha angida n. sp. and Bakuella nilgiri n. sp., were found in soil samples. Anteholosticha angida n. sp. differs from its cogeners in having a unique combination of characters – presence of colourless cortical granules, ~ 53 macronuclear nodules, ~ 3 micronuclei, ciliature with 3–4 buccal cirri in a row and 4 dorsal kineties. Bakuella nilgiri n. sp. is characterized by the presence of colourless cortical granules, ~ 98 macronuclear nodules, 3–4 micronuclei, ciliature with 4–8 buccal cirri in a row and a mid-ventral complex comprising of ~ 21 cirral pairs and 2–10 cirri in 2–3 rows reaching up to the level of the 6–11 transverse cirri.
