Protoperidinium Bergh (Dinophyceae) of the National Park Sistema Arrecifal Veracruzano, Gulf of Mexico, with a key for identification
The morphology of 46 species of Protoperidinium was studied based on 510phytoplankton net samples taken from May 2005 through February 2007 at 7 stations inthe northwestern part of the National Park Sistema Arrecifal Veracruzano, southern Gulfof Mexico.

| Sumario: | The morphology of 46 species of Protoperidinium was studied based on 510phytoplankton net samples taken from May 2005 through February 2007 at 7 stations inthe northwestern part of the National Park Sistema Arrecifal Veracruzano, southern Gulfof Mexico. Forty-three species are represented by vegetative cells and three species only bycysts (P. oblongum, P. cf. stellatum and P. subinerme). Descriptions with an emphasis on thefirst apical and the second intercalary plates and synonymy are given for each species. Cellsize variation, the mean and the standard deviation of three or four measurements are givenfor most species. The hypothecal pore in the first postcingular plate, a stable taxonomicfeature, was observed only in P. solidicorne, P. pellucidum, P. ovum, P. sp. E meta-hexaand P. cf. hirobis; the position of the pore is also a conservative characteristic. Twentyfivespecies are provided with affinities and taxonomic, nomenclatural or biogeographiccomments. A dichotomous key for identification of all the species found is presented, andspecies are illustrated with light microscope photographs. A new combination is proposed:Protoperidinium persicum (J. Schill.) Okolodkov comb. nov. Fifteen species are new recordsfor the Gulf of Mexico, and about 25 species for the state of Veracruz |
