Description
Macropisthodon rudis appears to mimic vipers, and the head takes a triangular shape when the snake takes a defensive position. However, it is only mildly venomous, although it is possible that its venomousness is underestimated.
The species grows to 120 cm (47 in) in total length. The head is broad and distinct from the neck. The dorsum is brown to grey brown, sometimes tinted with bronze, and interrupted by dark patterns of variable in size, disposition and intensity of pigmentation.
Female snakes give birth to 12–27 young per litter in late summer and autumn. The newly hatched young measure 13–20 cm (5.1–7.9 in) cm in total length.
Habitat and conservation
Macropisthodon rudis is a common species that inhabits montane meadows, riparian areas of brooks, valleys, road sides, shrubs, and rock piles. Its altitudinal range is 600–2,650 m (1,970–8,690 ft) above sea level.
The species is traded in significant numbers, which might present a localized threat. However, the overall population of this widespread species is stable and its conservation status is assessed as "Least Concern".
