Abstract
Ectopleura obypa, a new species referable to the family Tubulariidae, is de scribed from the southeastern coast of Brazil. Specimens were collected on experimental panels and other artificial substrates at depths from about 1 to 15 m. The hydroid stage is a remarkable green color when blastostyles ar e developed. A free medusa, with 2 opposed capitate marginal tentacles and 8 meridional tracks of nematocysts on the exumbrella, is present in the lif e cycle.
