Common names: dwarf pipe snakes.[2]

The Anomochilidae, or anomochilids, are a monotypic family created for the genus Anomochilus, which currently contains three monotypic species.[2]


The typical specimen has a small head, not distinct from the neck, with large, symmetrical shields. The eyes are very small, distinct from the surrounding shields. The nostrils are in a single nasal, which forms a suture with its fellow behind the rostral. The body is cylindrical. The dorsal scales are smooth, in 21 rows. The ventrals are very small, scarcely enlarged. The tail is extremely short and blunt.[3]

These three species much resemble those of the family Cylindrophiidae (Asian pipesnakes). However, they lack both a chin groove and teeth on their pterygoid.

Geographic range[edit]

They are found in West Malaysia and on the Indonesian island of Sumatra.[1]

T) Type species.[1]


The name of the genus was originally Anomolochilus, which was given to it by T.W. van Lidth de Jeude in 1890. In 1901, C. Berg pointed out the name was already occupied by a genus of Coleoptera (beetles), and he proposed as a replacement the name Anomochilus.[4]

The genus, together with Cylindrophis, was previously assigned to the subfamily Cylindrophinae under the family Uropeltidae, but both were removed by Cundall et al. (1993) to prevent a paraphyletic relationship.[1]
