Abstract

Specimens of the hydromedusa Cnidocodon leopoldiBouillon, 1978Bouillon, J. 1978. Hydroméduses de la Mer de Bismarck (Papouasie Nouvelle-Guinée. Partie I: Anthomedusae Capitata (Hydrozoa-Cnidaria). Cahiers de Biologie Marine, 19: 249-297. were collected in waters off the northeast Brazilian coast between 7.4°S, 34.3°W and 8.7°S, 34.8°W. The genus can be distinguished from other anthomedusae by the presence of four marginal perradial bulbs having an adaxial nematocyst cushion and branched capitate tentacles, an umbrella with scattered nematocysts, and gonads around a cylindrical manubrium shorter than the umbrella. Specimens were assigned to C. leopoldi due the tentacles with 4-5 branches and the absence of ocelli on tentacle bulbs differing from the congeneric Cnidocodon ocellataHuang, Xu, Lin & Qiu, 2008Huang, J.; Xu, Z.; Lin, J. & Qiu, M. 2008. Three new species of Anthomedusae (Hydrozoa, Hydroidomedusae) from the Fujian Sea Water. Journal of Xiamen University (Natural Science), 47: 408-412..
