Cyathella is a monospecific hexactinellid sponge genus, whose systematic position within the Hexactinellida has been so far unresolved. The original material of the type species, C. lutea SCHMIDT 1870, which has been re-examined, is here re-described and the genus is revised. The dictyonal skeleton of C. lutea is investigated, and a new subfamily Cyathellinae is erected to comprise this special type of skeletal architecture. C. lutea is compared with fossil hexactinellid species attributed to this new sub-family.
