Euprepiophis mandarinus, commonly known as the Mandarin rat snake, is a species of nonvenomous colubrid snake endemic to Asia. It is closely related to Euprepiophis conspicillatus, the Japanese forest rat snake. Mandarin rat snakes are one of the most popular rat snakes found in the pet trade.

Description

It is a relatively small rat snake; adult size is 1.4 m (4 ft 7 in) or less in total length (body + tail).^[3]

Distribution

India (Arunachal Pradesh), Myanmar, Laos, Vietnam, Taiwan, China (Anhui, Beijing, Chongqing, Fujian, Gansu, Guangdong, Guangxi, Guizhou, Hainan, Hebei, Henan, Hubei, Hunan, Jiangsu, Jiangxi, Liaoning, Shaanxi, Shanghai, Shanxi, Sichuan, Tianjin, Tibet, Yunnan, Zhejiang)^[1]

Type locality: China: Chekiang, Chusan island (modern transliteration: Zhejiang, Zhoushan) (Cantor, 1842)^[4]

Taxonomy

In recent years there has been some taxonomic controversy over the genera of rat snakes. Based on mitochondrial DNA, Utiger et al. (2002)^[5] argued for a splintering of the genus Elaphe and suggested a reworking of the genera.^[6]

Natural history

The Mandarin rat snake is a secretive species, often using rodent burrows for shelter. It feeds primarily on small rodents, prefers cooler temperatures, and is predominately crepuscular. It occurs from sea level to at least 3,000 m (9,800 ft).
