About the Burrowing Ratsnake

Euprepiophis conspicillata, commonly known as the Japanese forest rat snake, is a species of nonvenomous colubrid snake endemic to Japan. Its Japanese common name, jimuguri, roughly translates to "the burrower". It is closely related to Euprepiophis mandarinus, the Mandarin rat snake.

Euprepiophis conspicillata is native to all four main islands of Japan, including some smaller outlying islands, as well as Kunashir Island (territory disputed between Japan and Russia). Adults are usually 70 to 100 cm (2.3 to 3.3 ft) in total length (body + tail).

In recent years there has been some taxonomic controversy over the genera of rat snakes. Based on mitochondrial DNA, Utiger et al. (2002) argued for a splintering of the genus Elaphe and suggested a reworking of the genera.

However, all published taxonomy remains a taxonomic suggestion until ruled on by the International Commission on Zoological Nomenclature (ICZN - https://www.iczn.org/), but that body has so far not supported the change and has not addressed the taxonomic suggestion. Thus the official taxonomy remains Elaphe.
