A new marine dinoflagellate genus, Testeria gen. nov., is reported from coral reef‐mangrove pond. A new generic name is proposed for two species: Testeria novellus sp. nov. and a new combination fot Testeria steidingerae (Balech) comb. nov. These two species differ in thecal plate morphology from Protoperidinium species based on the following characteristics. Plates of Testeria novellus and T. steidingerae exhibit: 1) a wide, symmetric, ortho apical plate 1' disconnected from a slender apical horn and in direct contact with the cingulum. 2) apical pore complex absent. 3) anterior intercalary plate (2a) hexa situated dorsally. The thecal plate formula is as follows: 4′, 3a, 7′′, 4c)3+t), 5′′′, 6s, 2′′′′. Cells are colorless or pale pink, chloroplasts absent. The similarities and differences of Testeria and Protoperidinium are discussed with respect to their taxonomical history, species associations and ecology.
