Alan: In a case like this, it would be wise choice to do to mentioning of the references for your direct referrings. For the information of others, above represented phylogenetic tree is originally published from Nature: Biju, S.D. & Bossuyt, F., 2003. New frog family from India reveals an ancient biogeographical link with the Sheychelles. Nature, Vol. 425:711-714.
For the information of Duo and Elisabeth, I doubt that as a herpetocultural species, this species would never be a member of that group, since it is already under great threat in its natural surroundings (see e.g. Aggalwal, R.K., 2004. Ancient frog could... Nature, Vol. 428:467). Unfortunately, that is the situation right now...
However, it is still very fascinating and interesting species of Anura, indeed.
