Cyriocosmus ritae, from western Brazil (Humaitá, Rio Branco, Acre) and adjacent eastern Peru (Río Callería, Colonia), is a remarkable member of the genus. Coloration and pattern are different from the orange/black of its cousins. Yet it is every bit a dwarf species of the Cyriocosmus type, with keeping requirements identical to those used for Cyriocosmus in general. C. ritae is hardy, eats well, and grows fast. It has not been available on a yearly basis, but hopefully that will change. It deserves space in any dwarf collection where it quickly becomes a favorite.
