Fantastic!

New frog from India was considered to be a member of new Anuran family:

This cute little guy is Nasikabatrachus sahyadrensis, a new species and a member of a new family of frogs recently discovered in India. His closest relatives are found in the Seychelles, far away in the Indian Ocean, which dates their separation way back in the Mesozoic. The discovery is cool for another reason:

Just how significant is the discovery of another family of frogs? Only 29 families are known, encompassing the approximately 4,800 known species. Most of these families were named by the mid-1800s, and the last discovery of a species of frog belonging to a new family, as opposed to merely a taxonomic rearrangement, was in 1926. All others date to the 1700s and 1800s, making this a once-in-a-century find. Moreover, according to fossils and evolutionary ‘clocks’ devised using molecular data, families of frogs are about as ancient as orders and superorders of mammals, having diverged from one another during the heyday of the dinosaurs in the mesozoic era (251-65 million years ago).

Nasikabatrachus sahyadrensis Biju and Bossuyt, 2003, Nature, 425: 711. Holotype: BNHS 4202, by original designation. Type locality: "Disturbed secondary forest near a dardamom plantation at Kattappana (09˚ 45´ N, 77˚ 05´ E), altitude approximately 900 m), Idukki district, Kerala, Western Ghats, India".

I could not even imagine that such fantastic animals still can be found!

Indeed!

Despite I am studying amphibians for last 7 years I was sure that all families are already known! At least any new families could be obatined by splitting old taxons into several monophyletic lineages.

But this is absolutely new form of frog, very different from anything we knew afore this outstanding discovery!

So we should keep our eyes open wide, even in the XXI!
