This family is known only from the Western Ghats of India and from Sri Lanka. Several studies confirm the monophyly of this ancient clade, which originated in the tropical mountains in India in the mid to late Cretaceous (Van Bocxlaer et al. 2012).

Most species from this family are in the genus Nyctibatrachus, which occur in the Western Ghats of India. Lankanectes occurs in forests of Sri Lanka.

News Highlight
February 27, 2017: The Night Frogs, Nyctibatrachidae, is a small, ranoid family endemic to the Western Ghats in peninsular India. Until now, the moderate-to large-sized species (up to more than 80 mm body size) have been primarily stream-dwelling. Research in the Western Ghats continues to be productive, with new species from several families being announced at regular intervals, and it is widely recognized as an important biodiversity hotspot. Garg et al. (2017) discovered seven new nyctibatrachids, but what is special about this find is the first miniaturized species in the family. Four of these new species, roughly 12 - 15 mm body size, were found in damp forest floor leaf litter and marsh vegetation. Apparently all have a tadpole stage. They have been overlooked in the past because of the small size, insect-like call, secretive habits and different habitat preferences, and they are locally abundant. Nevertheless, these habitats are subject to strong anthropogenic influences. The authors estimate that about one-third of nyctibatrachids are threatened with imminent extinction. (DW)
