| A new marine benthic Prorocentrum species from sandy habitats of South Brittany (northwestern France), P. consutum sp. nov., is described using LM and SEM and molecular phylogenetic analyses. Cells have a subcircular to broadly ovoid shape and are plainly flattened. They are 57-61 lm long and 52-55 lm wide. A central pyrenoid is present, and the kidney-shaped nucleus is positioned in the posterior region. In right valve view, the periflagellar area is deeply excavated, and the left valve forms a prominent apical ridge. The periflagellar area consists of nine platelets, and a small narrow collar is present around the flagellar pore. The ornamentation of this new species is very peculiar and is characterized by a ring of round areolae located at the... |

| A new benthic dinoflagellate species, Prorocentrum bimaculatum sp. nov., is studied from Kuwaits marine sediments, based on detailed morphological and molecular data. Cells are large, oblong oval in shape. They are 49.955.3 mu m long and 38.443.2 mu m wide. The ornamentation of this new species is peculiar, and characterized by smooth valves with large pores (0.320.50 mu m) scattered on their surface, except in two circular patches of similar to 15 mu m in diameter, devoid of ornamentation and located on both sides of the valve centers. The periflagellar area is widely triangular, located in a moderate excavation of the right valve, and comprises nine platelets. The intercalary band of P. bimaculatum is smooth. The molecular phylogenetic position of this... |

| About 30 benthic Prorocentrum species have been described, some of which producing okadaic acid and derivatives involved in diarrhetic shellfish poisoning. The western Caribbean has been extensively studied for benthic dinoflagellates associated with ciguatera, and fifteen Prorocentrum species were described from mangroves and coral reefs of Belize. In contrast, no study reported the diversity of this genus in the Eastern Caribbean, especially in the Lesser Antilles. This study adds to the biodiversity knowledge in Martinique Island by investigating one site of the Caribbean coast from 2010 to 2017. Sediment samples were collected each year in March and studied taxonomically. Identification was realized morphologically by scanning electron microscopy,... |

| El género Prorocentrum Ehrenberg, incluye 81 especies, 21 son consideradas formadoras de florecimientos algales nocivos, de las cuales aproximadamente nueve especies producen toxinas. Considerando lo anterior, el objetivo de este trabajo consistió en determinar la distribución y abundancia de las especies del género Prorocentrum durante un ciclo anual, en dos estaciones de muestreo ubicadas dentro del ámbito de las granjas atuneras y en una estación fuera de la influencia de las granjas en la Bahía de La Paz, Golfo de California. Las muestras de agua se recolectaron mensualmente (junio 2006-mayo 2007) con una botella van Dorn en diferentes niveles de profundidad. En San Juan de La Costa (SC) se recolectaron en superficie 25 y 50 m, en Rancheros del Mar... |

| Este estudo teve por objetivo identificar as morfo-espécies de dinoflagelados do microplâncton (>20 μm) das Ordens Peridiniales e Prorocentrales ao largo do Cabo de Santa Marta Grande, CSMG (SC, 28º 40' S) e Albardão-Chuí, AC (RS, 34º 40' S) durante dois cruzeiros oceanográficos: inverno de 2005 e verão de 2007. Amostras de plâncton foram coletadas através de arrastos verticais com rede de plâncton (20 μm), preservadas com formalina 4% e analisadas ao microscópio invertido equipado com câmara digital. Quando necessário, a identificação de espécies de Peridiniales foi efetuada através do número e morfologia das placas da teca realçadas com Calco Flúor Branco MR2; espécies de Prorocentrales foram identificadas com base em seu tamanho, forma, presença de... |
