Country

India

Types

Only a holotype has been assigned: ICAR-NBFGR/CHAPMAH.1 127mm SL

Distribution

Known only from the type locality: A well near to Thiruvalla, Pathanamthitta District, Peringara, Kerala, India

Habitat

The true habitat is not known as the only sample was from a well.

Systematics

A COI sequence shows a 12.3% distance bewtween A. mahabali and the only other species in the genus A. gollum (Kumar et al. 2019). This is not surprising given the distance between type localities (over 200km), and the presence of a major biogeographic barrier, the Palghat Gap, between them.

Biological Notes

The title of the paper containing the original decscription of this species states that the species is troglophilic. This term is used for animals which are found in both epigean (surface) and hypogean (subterranean) habitats and are equally able to live successfully in both (Trajano and Carvalho 2017) . Since this species is currently known from a single specimen taken from a hypogean habitat its presence in epigean waters is currently unknown. Therefore any assesment as to whether is is troglophilic is premature. The animal does not appear, from photographs in the paper and videos (see below for links), to be even slightly troglomorphic despite it being described as such in the Introduction to the paper. Its present status should be currently be considered as unconfirmed.
