This torrent species is differentiated from all known species in the genus by its very large size (snout vent length range 52–84 mm), stout body, rough and highly wrinkled dorsum, presence of two prominent folds in the tympanic region, prominent vomerine teeth located horizontally on highly-elevated strong ridges situated far behind the choanae. Hindlimb is short, tibio-tarsal articulation reaching the tympanic region, tips of fingers and toes dilated into prominent discs with circum-marginal grooves. Prominent and highly developed tubercles equal to the size of their respective terminal phalangial discs are present.

This species of Nyctibatrachus is described from the Western Ghats part of Kudremukh National Park, Karnataka, South India. Kudremukh National Park is located in the central Western Ghats (13°10'– 13°26'N and 75°05'–75°10'E) and comprises highly complex vegetation mosaic of tropical evergreen forest, shola-grassland and mixed semi-evergreen forest, richly nourished by several hill streams and torrents.

This large and robust species of Nyctibatrachus was recorded from a torrential stream ‘Kadambi Hole’, flowing through the Kudremukh National Park (altitude: 850–1110 m msl). These frogs inhabit caves beneath the boulders in the riffle zone of water.
