Recently our paper on the The phylogenetic position of Lepidopygopsis typus (Teleostei: Cyprinidae), a monotypic freshwater fish endemic to the Western Ghats of India has been published. This is an important work and a significant contribution to the Ichthyology of the Indian Peninsula, since it clears a longstanding misconception.

First of all, let me say that the species Lepidopygopsis typus a monotypic freshwater fish endemic to the Periyar Tiger Reserve (PTR) forests, is a relative of the Mahseers, and allied large barbs distributed in India, Pakistan, Afghanistan, Iran, Nepal and several North African regions.

It was until now confused to be a species within the “schizothoracinae”, which comprise the hill trouts or the mountain barbells of the Himalayas. The “disjunct distribution” has baffled ichthyologists and biogeographers at the same time.

Now we show that it is just a case of a “false disjunct” which arose due to improper systematic position of the species.

Here, using phylogenetic hypothesis testing, and using both mitochondrial DNA and nuclear DNA phylogenies we solve the puzzle. All are welcome to read the paper and comment on it. If the readers need a full text of the paper please feel free to mail me or one of my co-authors who will happily share it with you for non-profit/research purposes.
