Argyrophis diardii, commonly known as Diard's blind snake, the Indochinese blind snake, the large blind snake, or the large worm snake, is a species of harmless snake in the family Typhlopidae. The species is endemic to South Asia and Southeast Asia. ^[1] There are two recognized subspecies.

Taxonomy

A. diardii was first described by Hermann Schlegel in 1839, as Typhlops Diardii. ^[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". ^[3]

Etymology

Both the specific name, diardii, and the common name, "Diard's blindsnake", are in honor of French naturalist Pierre-Médard Diard. ^{[4] [5]}

Subspecies

Two subspecies of Typhlops diardii are recognized as being valid, including the nominotypical subspecies: ^[2]

• Argyrophis diardii diardiiSchlegel, 1839 ^[4]
• Argyrophis diardii platyventris Khan, 1998 ^[6]

Description

A. diardii is heavy-bodied for a blindsnake. It has 22–25 scale rows around the body at midbody. The belly is distinctly flat. ^[2]

Distribution and habitat

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. ^[1]
