| Cette thèse a pour objectif principal la caractérisation taxonomique, physiologique et écologique d’espèces de dinoflagellés associées à des alertes de toxicité dans le golfe de Gabès à savoir : Alexandrium minutum, Prorocentrum lima, Coolia monotis et Ostreopsis ovata. L’optimisation des conditions de culture des espèces de dinoflagellés et la mise en place d’une phytothèque composée d’une collection de cultures de microalgues toxiques étaient notre priorité dans cette investigation. Une analyse de la base des données REPHY a été effectuée dans le cadre de cette thèse. L’étude taxonomique moyennant la microscopie électronique en transmission et à balayage nous a permis de déceler les importantes caractéristiques morphologiques de distinction pour chaque... |

| Dothiorella and Spencermartinsia are two botryosphaeriaceous genera with dark 2-celled conidia and found in parasitic, saprophytic or endophytic association with various woody host plants. Based on ITS and EF1-α sequence data and morphology, eight new species are described from Iran, New Zealand, Portugal and Spain. Of these, five species are placed in Dothiorella, namely D. iranica, D. parva, D. prunicola, D. sempervirentis and D. striata, and three species belong to Spencermartinsia named as S. citricola, S. mangiferae and S. plurivora. An identification key to the species of each genus is provided. |

| Species in the Botryosphaeriaceae are well known as pathogens and saprobes of woody hosts, but little is known about the species that occur in Iran. In a recent survey of this family in Iran two fungi with diplodia-like anamorphs were isolated from various tree hosts. These two fungi were fully characterised in terms of morphology of the anamorphs in culture, and sequences of the ITS1/ITS2 regions of the ribosomal DNA operon and partial sequences of the translation elongation factor 1-α. Phylogenetic analyses placed them within a clade consisting of Barriopsis and Phaeobotryon species, but they were clearly distinct from known species in these genera. Therefore, they are described here as two new species, namely Barriopsis iraniana on Citrus, Mangifera and... |

| Genus Maerua has around 60 species represented on the African continent, of which three have been reported for Angola. Two new species of Maerua (Capparaceae) from Angola are here described. Both are closely similar to M. juncea subsp. juncea, being distinguished by floral traits such as the receptacle, androphore and gynophore (M. pintobastoae) or leaf traits such as venation, as well as size and shape of the ovary and disc shape (M. mendesii). A key for Maerua species occurring in Angola is provided, as well as a table summarizing and comparing the morphological characters for the new species and similar African species. With the description of these two new species, the genus Maerua comprises five species in Angola. Resumo O género Maerua tem cerca de... |

| Hasta el momento se han identificado catorce especies de peces de la familia Pomacentridae en el Caribe colombiano. Siete de ellas en el género Eupomacentrus, incluyendo E. dorsopunicans, E. planifrons, E. partitus, E. leucostictus, E. meliis, E. variabilis y la estuarina E. otophorus. Las dos especies de Abudefduf del Caribe son conocidas en Colombia, A. saxatilis y A. taurus. Microspathodon chrysurus es uno de los pomacentridus más abundantes en los arrecifes coralinos colombianos, destacándose los juveniles de esta especie, pues desarrollan un comportamiento especial, que se expresa picando los costados de los peces que solicitan limpieza, disturbándolos. Chronih posee cuatro especies conocidas en el área, C. cyanea y C. muliilftieafa, que habitan en... |

| This is the first revision for the representatives of the genus Caiophora (Loasaceae) in Chile. The genus is widely distributed in the Andes from Argentina/Chile in the South to Central Ecuador in the North, and comprises approximately 60 species. In Chile only five species are present, Caiophora chuquitensis, C. cirsiifolia, C. coronata, C. deserticola sp. nov. and C. rosulata. Caiophora rosulata is here subdivided into two subspecies: western Andean C. rosulata subsp. rosulata (present in northern Chile and southern Peru), and eastern Andean C. rosulata subsp. taraxacoides, stat. and comb. nov. Furthermore C. superba syn. nov. and C. macrocarpa syn. nov. are placed into synonymy under C. chuquitensis, and C. rahmeri syn. nov. is synonymized to C.... |

| From now on, the genus Bragasellus Henry & Magniez, 1968 includes 2 oculated and 17 stygobiotic species. As a natural and monophyletic taxonomic unit, we consider it a good genus. Its original area corresponds to the north-west quarter of the Iberian Peninsula. Secondarily, this area has extended eastward, using mainly the alluvial channels of hydrographic systems (Ríos Douro + Ebro and tributaries), finally reaching the underground waters of several Mediterranean rivers. This active expansion is exclusively due to the migration of two stygobiotic sibling species: B. lagari Henry & Magniez, 1973 towards the high basin of the Río Tajo, then downstream to the basins of the Ríos Jucar and Turia (Prov. Valencia); and B. lagarioides n. sp., downstream... |

| ABSTRACT The number of studies on Neotropical mantises has been growing in recent years, and the systematics of Mantodea is now a dynamic field with noteworthy contributions. Several taxonomic revisions have been published recently. The taxonomy of Paraphotina Giglio-Tos, 1915 is reviewed as part of current studies on systematics of Neotropical Mantodea. Currently, Paraphotina contains four species from South America: P. caatingaensis (Menezes & Bravo, 2013) comb. nov., P. insolita (Rehn, 1941), P. occidentalis Lombardo, 1998 and P. reticulata (Saussure, 1871). Paraphotina venezuelana Beier, 1963 is a new junior synonym of P. insolita . Keys for the Paraphotina species are proposed. The distribution of Paraphotina species is apparently correlates with... |

| The number and identity of the species of black widow spiders of the genus Latrodectus that inhabit Chile remain unclear. Here we present results of taxonomic work based on morphologic and molecular characters of a large series of specimens collected throughout Chile, which aimed to assess Chilean Latrodectus diversity. Results show that all studied populations belong to a single species, for which the correct name is Latrodectus thoracicus Nicolet 1849. Therefore, we remove this taxon from the synonymy of L. mactans (Fabricius, 1775). In addition, we suggest that L. mirabilis (Holmberg, 1876) may be junior synonym of L. thoracicus. We recognize two species of black widows for continental Chile, L. thoracicus andi. variegatus Nicolet, 1849. We provided an... |

| Eumycetoma is a chronic fungal infection characterised by large subcutaneous masses and the presence of sinuses discharging coloured grains. The causative agents of black-grain eumycetoma mostly belong to the orders Sordariales and Pleosporales. The aim of the present study was to clarify the phylogeny and taxonomy of pleosporalean agents, viz. Madurella grisea, Medicopsis romeroi (syn.: Pyrenochaeta romeroi), Nigrograna mackinnonii (syn. Pyrenochaeta mackinnonii), Leptosphaeria senegalensis, L. tompkinsii, and Pseudochaetosphaeronema larense. A phylogenetic analysis based on five loci was performed: the Internal Transcribed Spacer (ITS), large (LSU) and small (SSU) subunit ribosomal RNA, the second largest RNA polymerase subunit (RPB2), and translation... |

| The deep-sea squat lobster, Munidopsis serricornis (Loven, 1852), originally described from the north-eastern Atlantic, has long been considered near cosmopolitan with numerous reports also from the western Pacific and northern Indian Ocean. These Indo-West Pacific records are reviewed along with new material from seamounts throughout the region. Munidopsis serricornis sensu stricto is restricted to the Atlantic Ocean. Six new species are described from the Indo-West Pacific: M alcocki sp. nov. from the central to western Indian Ocean; M atlantis sp. nov., from the Southwest Indian Ridge; M macphersoni sp. nov. from the Austral Islands, French Polynesia; M spiridonovi sp. nov. from the western Indian Ocean; M nias sp. nov. from southern Indonesia and the... |
