Pterinochilus murinus or the orange baboon tarantula,[2] is a nocturnal spider in the family Theraphosidae that was first described in 1897 by Reginald Innes Pocock.

[5] These nicknames reference a particular orange colour form that is prized in the hobby for its beauty, as well as its painful bite.

There are currently 5 known colour variants of Pterinochilus murinus: and also localities of those as listed after the color form names.

Consequently, it is not recommended that hobbyists keep this species without extensive prior experience handling venomous spiders.

These spiders build a tunnel shaped web and as adults should be provided around 2 - 3 inches of substrate.

Although their venom is not known to be lethal to humans, it is considered medically significant and thus it is advised to avoid handling this species.
