Asian Tree Toads

This genus contains only two species at the moment, R. rugosus and R. hosii.

These are moderately stocky toads which spend most of the time up in the trees. The inhabit South India, the Malay Peninsular, Borneo and Sumatra.


The Frogs of Borneo

We exclusively cover frogs from the island of Borneo. To navigate to them, use the family navigation in the left sidebar or the list below.  Once you are in the respective family, there will be a list with genera and species in the right sidebar to navigate directly to the species you want to see. 

For a comprehensive compilation of the latest frog taxonomy and a list of all frog families and species see Amphibian Species of the World by Dr. Darrel Frost, American Museum of Natural History, New York. We are grateful to Dr. Frost for letting us cross-link to his database for taxonomic information on each species.

Amphibia Web is a scientific web site with coverage of currently recognized amphibian taxa. It applies a more conservative taxonomy of frogs. It offers a wealth of informations, such as species descriptions, images of species, sound files, country searches, distribution maps, amphibian declines... and a lot more.

This website is dedicated to the frogs of East Malaysia (Borneo) and their larval forms. It covers more than 100 species, each with an easy to access page, biological information, color image of adult, and many of them with color images of their larval forms.

Our mission: Easy access, easy use, unique imagery, and reliable information. We want to serve a broad range of users. We keep it as simple as possible, but provide you with further links and reading suggestions to deepen your knowledge. We like to be in touch with you; send us your field observations!

Taxonomy is an active research field. New insights lead to amendments. Species previously considered an evolutionary unit are split up into several species and new species names come into play. This may seem confusing for some, but only documents how little we still know about the true diversity of Bornean frogs. We expect many discoveries in the future. We try to keep track on this site as good as we can, however, we always try to keep the general user in mind. There are dedicated web sites that list the latest on frog taxonomy. In particular, we recommend Amphibian Species of the World as the most comprehensive and most up-to-date source for taxonomic species accounts in amphibians.
