It is endemic to the islands of Borneo and Sumatra, where it inhabits montane and lowland dipterocarp forest at altitudes of 300–1,000 m (980–3,280 ft).

Described by the herpetologist Theodorus Willem van Lidth de Jeude in 1890, the species is a stout, cylindrical snake with a small head and short, conical tail.

The IUCN Red List currently classifies A. weberi as being data deficient due to a lack of information about its range and threats to the species; however, it may be threatened by habitat loss caused by logging and urbanisation.

[6] The specific name, weberi, is in honor of German-Dutch zoologist Max Wilhelm Carl Weber van Bosse.

[10] The head is continuous with the neck, and, despite the fossorial (adapted to living underground) nature of the species, the snout has no reinforcements to aid in burrowing.

[4] It differs from both A. monticola and A. leonardi by the presence of pale stripes along its sides and a paired parietofrontal scale on the forehead.

[3] The species lays eggs in clutches of four; this is unique within the superfamily Uropeltoidea, the rest of which give birth to live young.

[3][4] The species is currently classified as being data deficient by the International Union for Conservation of Nature due to a lack of information about its range, population size, and threats affecting it.
