|Scientific name||Lampropeltis ruthveni|
|English name||Ruthvens Kingsnake; Querétaro Kingsnake|
|Distribution||In the following states of Mexico: Michoacán, Queretaro, Jalisco, Hidalgo, Guanajuato and possibly also in Durango.|
|Habitat||Thorns and pine covered rocky areas between 1500 and 2250 meters high on the Mexican Plateau.|
|Details||Ruthvens kingsnake was first described in 1920. Soon after this, it was described as a subspecies of L. triangulum, but in 1994 Liner gave them back the species status.
This Mexican species is on average about 60 cm long, with peaks of up to about 90 cm. At birth, they are between 18 and 22 cm long.

Little is known about the reproduction in the wild. This probably will not differ much from the other Lampropeltis species. Probably a brumation of several months, copulations in the spring, eggs in the early summer and young in the late summer.
Also about the way of life is not much known. During the day they seem to live mostly in the humus layer of the biotope. But also under tree stumps, stones etcetera. They are usually active in the late evening and at night.
In the wild, this soil-dwelling species most probably predominantly feeds on lizards and small rodents. Snakes may occasionally be eaten as well.
Due to deforestation and catching them to sell to hobbyists, this species is threatened in its survival in some areas. The relatively small habitat of around 20,000 km2 also plays a role in this.
The care in the terrarium seems to be easy/problem-free. Later more about this.
