A new species of Cinachyra Sollas (Porifera, Spirophorida) was dredged from 500 m depth off Espirito Santo State, SE Brazil, by Project REVIZEE Central SCORE. Cinachyra helena sp. nov. is characterized by the presence of a single category each, of protriaenes, anatriaenes, anisoactinal choanosomal oxeas, isoactinal cortical oxeas, and sigmaspires. The cortex is formed by small isoactinal oxeas arranged obliquely to the surface, and an anchoring basal spicule mass is absent. This is the first valid record of Cinachyra from the Atlantic; all similar species lacking a cortex should be transferred to Cinachyrella or other genera of Tetillidae. At the present state of knowledge, there are four valid species in the genus Cinachyra: C. barbata Sollas, C. crustata (Wilson), C. uteoides Dendy, and C. helena sp. nov.
