An amateur naturalist has found a new species of fish in an Arunachal Pradesh river and named it Garra Magniduscus meaning ‘huge disc fish’.
The medium-sized fish of the genus 'Garra' was found in the Upper Siang district by Lakpa Tamang, a former staff of the Northeast unit of the GB Pant Institute of Himalayan Environment and Development.
The discovery has been recently published in a reputed German international journal "Ichthyological Exploration of Freshwaters," institute director PP Dhyani said.
Tamang has described the species taxonomically and designated it as Garra magnidiscus (in Latin 'magnus' means large and 'discus' means disc) which is an allusion to the very large adhesive disc of the species. The disc is located in the posterior region of its mouth enabling it to easily station itself in fast-flowing water.
The genus 'Garra' includes about 80 species found in an area spread from China through the Middle East and Arabian Peninsula to East and West Africa. "Seventeen such species are known to exist in Africa and nine in the Arabian Peninsula. The sighting of the new species takes the total number of Garra species found in the Northeast to 17," Tamang said.
So far, 10 species of Garra are found in Arunachal Pradesh, Tamang said.
He reportedly discovered three new species of catfishes – Erethistoides senkhiensis, Glyptothorax Dikrongensis and Pseudolaguvia viriosa from Senkhi stream, Dikrong river in Papum Pare and Sille river in East Siang districts respectively in the last few years while working with the institute.
