Spinular Night Frog

The spinular night frog (Nyctibatrachus acanthodermis) is endemic to the Western Ghats, known from Kerala and Tamil Nadu, where the specimens used to describe it were collected. It was described in 2011 as one of 12 new species in its genus by the herpetologist Sathyabhama Das Biju and colleagues. It is a large night frog, with adult males measuring 52.9-66.2 mm in snout-vent length (Wikipedia, general species account).

It has a brownish-grey back, a grey underside, dark brown limbs and dark grey feet; preserved in ethanol it is black above with greyish-brown undersides. The head is wider than long, and the ovoid snout is longer than the diameter of the eye (Wikipedia, general species account).
