Cyriocosmus bertae
Cyriocosmus • Theraphosidae
A tiny, jewel-like dwarf with a golden-bronze heart-shaped abdominal marking. Rare in the hobby, so species-specific data is thin — care follows the Cyriocosmus genus (as for the well-known C. elegans): a small terrestrial/burrowing setup with lightly moist substrate, a hide, and a small water dish, warm (low-to-mid 80s) to grow it out in about two years. Docile and confident, not prone to bolting. New World: urticating hairs, non-medically-significant venom. A great dwarf for beginners short on space.
