Protoperidinium bergh (Dinophyceae) of the National Park Sistema Arrecifal Veracruzano, Gulf of Mexico, with a key for identification

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

Se estudió la morfología de 46 especies de Protoperidinium con base en 510 muestras de fitoplancton de red tomadas desde mayo de 2005 hasta febrero de 2007 en siete sitios georeferenciados en la parte noroeste del Parque Nacional Sistema Arrecifal Veracruzano, en el sur del Golfo de México. Cuarenta y tres especies están representadas por células vegetativas y tres sólo por quistes (P. oblongum, P. cf. stellatum y P. subinerme). Para cada especie se dan las descripciones con énfasis en la primera placa apical y la segunda placa intercalar, así como la sinonimia. La variación de tamaño de células, el promedio y la desviación estandar se presentan para la mayoría de especies. El poro hipotecal en la primera placa postcingular, un rasgo taxonómico constante, fue observado sólo en P. solidicorne, P. pellucidum, P. ovum, P. sp. E meta-hexa y P. cf. hirobis; la posición del poro es también una característica estable. Para 25 especies se proporcionan notas sobre sus afinidades, al igual que comentarios taxonómicos, nomenclaturales y biogeográficos. Se presenta una clave dicotómica para la identificación, así como ilustraciones de todas las especies encontradas. De éstas, 15 representan nuevos registros para el Golfo de México, y cerca de 25 especies lo son para el estado de Veracruz.
