The specific name, beddomii, is in honor of British army officer and botanist Richard Henry Beddome (1830–1911).

The head is covered in scales that have a sharp keel running along the centre, a feature also found in the Sri Lankan species (O. nigristigma and O. wiegmanni ).

The scales on the back are unequal in size with the larger ones forming regular V-shaped marks with the point facing backwards, enlarged ones sometimes forming regular chevrons on the back, with the point facing backward.

[4] A. beddomii is an oviparous species, with adult females laying clutches of 3–5 eggs.

[4] The distribution of A. beddomii is highly fragmented in patches of dense forest in the Western Ghats from and south of the Shencottah Gap.
