14. Triadinium polyedricum (Pouchet) Dodge, 1981

Diagnostic characters: Thecate dinoflagellate with an areolated surface. Body shape polyhedral. The equatorial girdle encompassed by conspicuous lists. Surrounding the apical pore are three almost equalsized plates, and near the antapex three additional plates are present. Antapex is flattened. Presence of crested thecal sutures. In some forms, a megacytic growth process takes place, altering the shape of some plates, since this growth produces wide pore-free bands ( Fig. 2p View Fig ).

Distribution: South Andaman region, India 20, Andaman Sea 3, 21, Bay of Bengal 13, Indian Ocean 11, ROPME Sea Area, Iranian coastal waters 25, Black Sea 27, Caribbean Sea 32, Mexican waters, Pacific Ocean 33, New Zealand coastal waters 30, Australian waters 31.

This species was recorded from the stations APK1, APK3, APK4 (surface and subsurface depths), and APK2 (subsurface depths) for the first time in Kakinada waters, and in the state of Andhra Pradesh.
