Nyctibatrachus manalari, the Manalar night frog, is endemic to the Western Ghats, known from Periyar Tiger Reserve in Kerala and Meghamalai Wildlife Sanctuary in Tamil Nadu, though its range is likely larger than currently known. In Tamil Nadu the frogs have been seen in secondary forest inside a plantation. It is a diminutive frog, with an adult male snout-vent length of 13.1-15.4 mm (Wikipedia, general species account).
It is mainly reddish brown with a pale patch on the snout, lighter undersides and dark brown horizontal lines on the limbs. It reproduces by laying eggs, and the only known clutch had eight eggs. Its calls are single-pulsed, each lasting 51.1 milliseconds, with a dominant frequency of 3.6 kHz (Wikipedia, general species account).
