Pseudorabdion albonuchalis is a species of snake in the family Colubridae. It is endemic to Borneo and occurs in Sabah and Sarawak (Malaysia), Kalimantan (Indonesia), and Brunei. It is also known as the white-collared reed snake.
Pseudorabdion albonuchalis has a small, slender body and a pointed head. It is oviparous.
Pseudorabdion albonuchalis occurs in lowland forest at elevations of 50m–600mm (160feet–2,000feetm) above sea level. It is semi-fossorial and lives in leaf litter. It is potentially threatened by deforestation. However, it has a wide range and occurs in many protected areas, and is therefore not considered threatened overall.
