About Lycodon fasciatus (Anderson, 1879)
Adults of Lycodon fasciatus can reach a total length of 53 cm (21 inches), with a tail that measures 11 cm (4¼ inches) long. The species has a distinct color pattern: broad purplish-black rings completely encircle the body, and these rings are separated by yellowish or reddish gaps. The first black ring does not wrap all the way around the neck. Dorsal scales are arranged in 17 rows; they are weakly keeled toward the front of the body, and the keels grow more pronounced toward the rear of the body. This species has 205 to 213 ventral scales, an entire anal scale, and 77 to 90 divided subcaudal scales. Lycodon fasciatus is distributed across India (Assam), Bangladesh, Myanmar, Thailand, Laos, Vietnam, Tibet, and southwestern China, where it occurs from Yunnan and Guangxi to Hubei, extending north to Shaanxi and Gansu, and also in Fujian and Sichuan.
