Paravaejovis spinigerus
A Sonoran Desert scorpion from the south-western United States and north-western Mexico with brownish stripes along the keels of its tail. It reaches about 6-7 cm, and its venom is not considered medically significant to people.
Paravaejovis spinigerus (Wood, 1863), known in English as the stripe-tailed or devil scorpion, is a scorpion of the family Vaejovidae; it was placed in Hoffmannius until 2013. It lives in the Sonoran Desert of north-western Mexico (Sonora, Baja California and Baja California Sur) and the south-western United States (Arizona, New Mexico and parts of California), sheltering under rocks and surface objects from the desert floor to rocky hillsides, and seeks out the most humid spots available. Brownish stripes run along the keels on the back of the tail, and it can be told from the Arizona bark scorpion (a buthid) because its tail is thicker than its slender claws and pedipalps. The species name refers to the spiniform granules at the ends of the dorsal tail keels. It is venomous, but the venom is not medically significant to humans or other mammals and is not considered dangerous. It feeds mainly on small invertebrates. In Japan it appears only occasionally at specialist shops.

It is not a member of the Buthidae, so it is not a designated invasive alien species in Japan. However, every scorpion species is on Japan's list of taxa that need an identification certificate, so imports must be accompanied by documents certifying the species. It is not listed by CITES (September 2026). Keep it in escape-proof housing and never release captive animals.

Carnivorous (small invertebrates such as crickets, mealworms and roaches)
It shelters under rocks and surface objects, so use a sandy substrate with flat stones or bark as hides. Keep singly.
Little data on keeping temperatures exist. It is a desert species but seeks out the most humid spots, so keep the enclosure mostly dry with slightly moist substrate under the hides.
Small prey such as crickets, mealworms and roaches sized to the scorpion. It also eats other scorpions, so do not house them together.
It is venomous, but the venom is not considered medically significant to people or other mammals. A sting still hurts, so do not handle it bare-handed; use tongs.
Scorpions escape through small gaps and loose lids, so use a container with a lockable lid. Always check the scientific name so it is not confused with the similar-looking Arizona bark scorpion, a buthid and a designated invasive species in Japan. Never release captive animals.
