Description
From Karawang, West Java, Indonesia

The Malayan krait may attain a total length of 108 cm (43 in), with a tail 16 cm (6.3 in) long.

Dorsally, it has a pattern of 27–34 dark-brown, black, or bluish-black crossbands on the body and tail, which are narrowed and rounded on the sides. The first crossband is continuous with the dark color of the head. The dark crossbands are separated by broad, yellowish-white interspaces, which may be spotted with black. Ventrally, it is uniformly white.

An unbanded black phenotype also occurs in some populations, reportedly in West and Central Java.[2]

The smooth dorsal scales are arranged in 15 rows, with the vertebral row much enlarged. The ventrals number 195–237; the anal plate is entire; and the single (undivided) subcaudals are 37–56 in number.[3]

Distribution and habitat

It is found in southeast Asia from Indochina south to Java and Bali in Indonesia.

Venom

In mice, the IV LD50 for this species is 0.1 mg/kg.[4] It has caused an untreated mortality rate of 60–70% on humans.[5]
