Abstract
Stragulum bicolor n. gen. & n. sp. (Octocorallia: Clavulariidae) is described from Brazil. It was found in shallow waters of the States of Ceara, Rio de Janeiro, Sao Paulo, Parana and Santa Catarina, and is probably invasive. The genus forms encrusting sheets on solid objects, such as seaweed basal stems, barnacle shells and artificial substrates. The new taxon has spindles, crosses and radiates in the outer layer of the coenenchyme, fused sclerites in the interior and the polyps are unarmed. The newgenus is compared with other taxa that have fused sclerites.
