Mahatha lacuna is only known from its type locality, near Galle, and is therefore considered critically endangered by the IUCN.^[6] The specific epithet lacuna, from the Latin for "hole", refers to the deep burrow in which the species was found.^[4]

Mahatha ornatipes

Mahatha ornatipes was originally described in 1915 by Roux as Paratelphusa ornatipes, and was later described as Ceylonthelphusa inflatissima Bott, 1970. It is widespread in the wet zone of Sri Lanka and is considered a species of Least Concern by the IUCN.^[7]
