The phylogeny of Heterocapsa sp. (Dinophyceae) isolated from the south coast of Iran during a Cochlodinium polykrikoides bloom

The genus Heterocapsa Stein is a relatively small armoured dinoflagellate. Because it has few differences in morphological characteristics among its species, species identification is difficult. In this study, small Heterocapsa sp. cells associated with a dense bloom of Cochlodinium polykrikoides Margalef were collected from the south-east coast of Iran.
