          Abstract

          The morphology of 38 species from eight genera of the order Dinophysiales was studied based on about seven hundred 20 μm phytoplankton net samples taken from May 2005 through April 2008 at 27 sampling stations in the National Park Sistema Arrecifal Veracruzano, southwestern Gulf of Mexico. Short descriptions and synonyms are given for each species. Cell size variation with the mean and the standard deviation are given for most species. Twenty-three species are provided with affinities and morphological, taxonomic and nomenclatural comments. Dichotomous keys for identification of the genera and species of Amphisolenia (4 species), Dinophysis (7), Heteroschisma (1), Histioneis (6), Ornithocercus (7), Phalacroma (9), Pseudophalacroma (1) and Sinophysis (3) are presented, and species are illustrated with light and scanning electron microscope photographs and line drawings. Phalacroma equalanti (Balech) Okolodkov comb. nov. is established. Thirteen species are new records for the State of Veracruz, and Histioneis isseli and Pseudophalacroma nasutum are new for the Gulf of Mexico.

          Translated abstract

          Se estudió la morfología de 38 especies de ocho géneros del orden Dinophysiales con base en aproximadamente 700 muestras de red fitoplanctónica (20 μm) tomadas de mayo de 2005 a abril de 2008 en 27 estaciones de muestreo en el Parque Nacional Sistema Arrecifal Veracruzano, la parte suroeste del Golfo de México. Para cada especie se dan descripciones cortas, así como la sinonimia. La variación del tama-o de las células, el promedio y la desviación estándar se presentan para la mayoría de especies. Para 23 se proporcionan notas sobre sus afinidades, al igual que comentarios morfológicos, taxonómicos y nomenclaturales. Se presentan claves dicotómicas para la identificación de los géneros y especies de Amphisolenia (4 especies), Dinophysis (7), Heteroschisma (1), Histioneis (6), Ornithocercus (7), Phalacroma (9), Pseudophalacroma (1) y Sinophysis (3), así como las fotografías en microscopio fotónico y microscopio electrónico de barrido e ilustraciones de todas las entidades encontradas. Se establece Phalacroma equalanti (Balech) Okolodkov comb. nov. Trece especies son nuevos registros para el Estado de Veracruz, e Histioneis isseli y Pseudophalacroma nasutum lo son para el Golfo de México.
