[4] The type locality of Schlegel's specimen was "Cochinchina [southern Vietnam]".
Saint Girons (1972: 32) described it as "Cochinchina sans certitude [southern Vietnam without certainty]", and Hahn (1980: 56) as "East Indies".
[4][5] Two subspecies of Typhlops diardii are recognized as being valid, including the nominotypical subspecies:[3] A. diardii is heavy-bodied for a blindsnake.
[3] A. diardii is found in India (Jalpaiguri-West Bengal, as far west as Dun Valley in Assam), Bangladesh, Myanmar, Thailand, Laos, Cambodia, Vietnam, the Malay Peninsula, Nias Island, Sumatra, Web Island (off northwest Sumatra), Bangka, and Borneo.
[1] The preferred natural habitats of A. diardii are forest, shrubland, and grassland, but it has also been found in agricultural areas.
