Scientific name Lampropeltis herrerae
English name Isla Todos Santos Sur Mountain Kingsnake
Habitat Open, rocky, sage-covered areas along the coast and also the rocky, scrubland-covered outback of the island.
Distribution This species only occurs on the southern island of the Isla Todos Santos, along the Pacific coast of Baja California, Mexico.
Details This species was previously considered a subspecies of L. zonata.

In 2002 this snake was described as a separate species by L. Grismer.

After 2002 the status of this snake has been changed a few times, but I do not have access to the scientific articles about this, so, for now, I consider this snake as a separate species…

This is a ground-dwelling snake species that leads a hidden life. They are, for the most part, coloured black and white.

Adult snakes are on average between 60 and 75 cm long. The length of new-born specimens is less than 20 cm.

I have found no data about the food in the wild until now. The same applies to data about keeping in captivity.

The habitat of this species is barely 100 square kilometres and is therefore seen as extremely vulnerable. The snake is therefore considered “seriously threatened” and the number of specimens within this small area seems to decrease.
In 1995 Mellink reports that snake traps have been found everywhere on the southern island of Isla Todos Santos. The captured snakes were meant for export. At the same time, the poachers caused considerable damage to the habitat in which the animals live. Numerous stones, which were used as hiding places by the snakes, were turned over and not returned, rendering them unusable. Also, rock masses were disrupted to catch snakes.

The island is not protected formally, but access is limited because it is a military outpost.
