Nyctibatrachus major, the Malabar night frog, large wrinkled frog, or Boulenger's narrow-eyed frog, is a species of frog in the family Nyctibatrachidae, commonly known as the robust frogs. It was described in 1882 by the zoologist George Albert Boulenger, and is the type species of the genus Nyctibatrachus. It is a large frog for its genus, with an adult snout–vent length of 31.5–52.0 mm (1.24–2.05 in) for males and 43.7–54.2 mm (1.72–2.13 in) for females. It is mainly brownish to greyish in colour, with a dark greyish-brown upperside, a greyish-white underside, and light grey sides. It also has a variety of grey or brown markings. When preserved in ethanol, it is mostly greyish-brown to grey, with whitish sides. Sexes can be told apart by the presence of the femoral glands (bulbous glands near the inner thigh) in males. The species is endemic to the Western Ghats mountain range of India, where it is found in Kerala, Tamil Nadu, and Karnataka.
