The dangerously venomous Bungarus magnimaculatus is endemic to Myanmar, recorded from Magway, Mandalay, and Sagaing Divisions. Recent surveys have found this species mainly in indaing (dipterocarp) forests (moist deciduous). The type locality for this species lies in seasonal dry forest and this species likely occurs throughout Myanmar’s central dry zone. Individuals have been found in disturbed habitats near villages and in agricultural areas. These snakes are active at night. (Leviton et al. 2003 and references therein)
Leviton et al. 2003 provide a technical description of Bungarus magnimaculatus: Dorsal scales in 15 longitudinal rows at midbody; subcaudal scutes undivided throughout; midorsal row of scales (vertebrals)strongly enlarged, as broad or broader than long; tail tapering, terminating in a point. Ventrals 214-235; subcaudals 40-48. Above, there are 11 to 14 broad, white crossbars, as wide as the black interspaces, the centers of each of the scales spotted with black.
