Specimens of Teissiera polypofera Xu, Huang & Chen, 1991 were found in waters off the northeast Brazilian coast between 8.858 degrees S, 34.809 degrees W and 9.005 degrees S, 34.805 degrees W and 56 to 717 m depth. The genus can be distinguished from other anthomedusae by the two opposite tentacles with cnidophores and four exumbrellar cnidocyst pouches with ocelli. Specimens were assigned to Teissiera polypofera due to the long and narrow manubrium transposing bell opening and polyp buds with medusoid buds on it, issuing from the base of manubrium. This study represents the first record of the genus in the Atlantic Ocean.
