Cyriocosmus bertae
A small South American Cyriocosmus. The genus comprises small to medium spiders with type III urticating setae. Despite the 'Peruvian' trade name, scientific records are from Brazil and Bolivia.
Cyriocosmus bertae Pérez-Miles, 1998 was described in a revision of Cyriocosmus, a genus of 24 small to medium tarantulas distinguished by male palpal and female spermathecal structures, all with type III urticating setae (Wikipedia). The species list gives its range as Brazil, and GBIF has only two records, from Acre (Brazil) and Santa Cruz (Bolivia). The trade name 'Peruvian' does not match this, so check whether spiders sold as Peruvian are this species or another of the several Cyriocosmus found in Peru, such as C. aueri or C. peruvianus. Care information for C. elegans describes a tiny species of about 5 cm leg span, with females living up to 7 years and males about 2, very fast and quick to retreat into its burrow. It is distinct from the two Cyriocosmus species already listed.

Not listed in the CITES Appendices (checked on Species+). Theraphosidae are neither designated invasive alien species nor taxa requiring an identification certificate on import in Japan (September 2026). Use a lockable enclosure to prevent escapes, and never release captive animals.

A small terrestrial burrower. Use a small enclosure with ample room relative to its leg span, with deep substrate, a hide and a small water dish.
Species data are scarce. Care information for C. elegans gives 20-24 C, with moist lower substrate and a drier surface.
Being small, it needs small crickets or roach nymphs. Remove uneaten prey and wait a few days after a moult.
All Cyriocosmus carry type III urticating setae; C. elegans relies more on speed than setae for defence. Keep setae away from eyes and skin.
The trade name does not match the recorded range and other Cyriocosmus may be sold under it; confirm the scientific name and origin. Small and fast, it escapes easily — never release captive animals.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The average lifespan of Peruvian dwarf beauty is Little data (congener C. elegans: females up to 7 years, males about 2). With proper care and nutrition, they can live a long and healthy life.
Peruvian dwarf beauty feeds on: Carnivorous (live insects such as crickets and roaches). Aim for a balanced diet with appropriate feeding frequency.
