Sundar, Arjun, Sidharthan, Dahanukar and Raghavan 2022
The species name is based on the Sanskrit word pâtâla, which means ‘below the feet’, denoting the subterranean realms of the universe—which are located under the earth’s surface. A noun in apposition.
Holotype: KUFOS.FT.2020.1, 32.1 mm SL.
Paratypes: KUFOS.FT.2020.2, 18.9 mm SL, KUFOS.FT.2020.3, 22.3 mm SL.
Known only from the type locality: Thiruvanvandoor, Kerala State, India (9°20’23.09”N, 76°34’48.54”E), 7 m asl. See map below.
In common with other subterranean fishes in the area (Horaglanis krishnai, H. alikunhii, H. abdulkalami, Kryptoglanis shajii, Kryptoglanis undet, Rakthamichthys indicus, R. roseni, R. digressus and Aenigmachanna gollum) this species probably inhabits very small openings within the laterite aquifer. These are probably of the order of 5-10cm maximum diameter though there may well me many kilometers of tunnels overall. Animals are only seen, and sampled, via man-made well used for water-supply purposes.
The two subterranean Pangio species are each others sister species (see below). Britz, Ali and Raghavan 2012 described the epigean Pangio ammophila from the Western Ghats. A phylogenetic tree of the genus Pangio, based on mitochondrial co1 gene, given in Sundar et al. (2022) shows that P. ammophila is the sister species to a clade composed of the two subterranean Pangio species, P. bhujia and P. pathala. It seems very likley that either P. ammophila is the direct ancestor of both subterranen species, or that all three of these are derived from a fourth, so far unknown, species.
As above only.
