| Litter frogs currently compose 11 genera that have about 112 species. They have an Oriental distribution and range from Pakistan to China and southward into Indonesia and the Philippines. All have aquatic eggs with some being laid in temporary ponds; others are laid in stream environments; most have large eyes and large mouths. Their body form tends to be plump with short legs, but their are exceptions (see the Leptolalax below). Adults are mostly terrestrial or semifossorial. The largest species reach 125 mm, the smallest species have adults in the 14-16 mm range. For many years these frogs were considered to be part of the Pelobatidae. Molecular studies suggest they need to be placed in their own family, but they do appear to form the sister group to the Pelobatidae. |
