Taxonomy

Argyrophis diardii was first described by German herpetologist 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]

The synonym, Typhlops Mülleri Schlegel, 1839, was named in honor of German naturalist Salomon Müller.[5]

Subspecies

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

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

Description

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

Geographic distribution

Argyrophis 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]

Habitat

The preferred natural habitats of Argyrophis diardii are forest, shrubland, and grassland, at elevations of 30–1,524 m (98–5,000 ft), and it has also been found in agricultural areas.[1]
