Eleven species of Dirivultidae (Copepoda: Siphonostomatoida) have been found at deep-sea vent areas on the Mid-Atlantic Ridge at the Snake Pit site, 23°23'N, 44°56'W depth 3,500 m, and near the Azores at the Lucky Strike site, 37°N, 32°W, depth 1,620 m. Rimipontius mediospinifer new genus, new species, is characterized by the formula 0-0; I for the endopod of leg 4 and by the presence of five setae on each caudal ramus. Aphotopontius atlanteus new species is distinguished by the length of the… Expand
Copepods of the family Dirivultidae (Siphonostomatoida) from deep-sea hydrothermal vent fields on the Mid-Atlantic Ridge at 14ºN and 5ºS
The discovery of dirivultids at 5oS represents the first record of copepods from a deep-sea hydrothermal vent southward of the Logachev field in the Atlantic Ocean. Expand
A new and primitive genus and species of deep-sea Tegastidae (Crustacea, Copepoda, Harpacticoida) from the Mid-Atlantic Ridge, 37°N (Azores Triple Junction, Lucky Strike)
The distinctive and primitive features of the new genus allowing an amendment of the family diagnosis are the elongate caudal rami, the 10-segmented male antennule and the leg 6 represen- ted by 2 small setae on the ventral side of the female genital double-somite. Expand
Dirivultidae (Copepoda: Siphonostomatoida) from hydrothermal vent fields in the Okinawa Trough, North Pacific Ocean, with description of one new species
Abstract Two species of dirivultid copepod (Siphonostomatoida), Stygiopontius senckenbergi Ivanenko & Ferrari, 2013 and Dirivultus kaiko sp. nov., were discovered from hydrothermal vent fields in theExpand
A new species of Exrima, synonymy of four species of Aphotopontius, Stygiopontius and Rhogobius, and record of first copepodid stage of Dirivultidae (Copepoda: Siphonostomatoida) from deep-sea hydrothermal vents of the East Pacific Rise (13°N)
Females of the new species Exrima walteri sp. nov. were found in sediment trap samples deployed over different sites of the East Pacific Rise (13°N) at 2600 m depth. Four traps were deposited duringExpand
Lecithotrophic nauplius of the family Dirivultidae (Copepoda; Siphonostomatoida) hatched on board over the Mid-Atlantic Ridge (5 S)
Morphological features of the planktonic nauplius of S. pectinatus suggest nutritional independence during their dispersal and the presence of two inner setae on the mandibular endopod is hypothesized to be a primitive character of dirivultids that distinguishes them from the remaining siphonostomatoid genera.

Advances in Taxonomy, Ecology, and Biogeography of Dirivultidae (Copepoda) Associated with Chemosynthetic Environments in the Deep Sea
Dirivultids have a world-wide distribution, but most genera and species are endemic to a single biogeographic region and thus can be considered the most successful taxon at deep-sea vents. Expand
Distributional and Biological Aspects of Copepods at Hydrothermal Vents on the Juan de Fuca Ridge, north-east Pacific ocean
The abundance patterns of copepods on the Juan de Fuca Ridge was examined and one species was studied in detail, finding that this copepod co-occurs with the alvinellid polychaete Paralvinella sulfincola. Expand
Sex ratio of Stygiopontius senokuchiae (Dirivultidae, Copepoda), an endemic copepod species at deep hydrothermal vent sites, is biased to males
It is suggested that neither population density nor chemoautotrophic food availability drives the sexual difference in the spatial distribution around vents among the adults of the Stygiopontius copepods species. Expand
Population structure and reproduction of the alvinocaridid shrimp Rimicaris exoculata on the Mid-Atlantic Ridge: variations between habitats and vent fields
A hypothetical scenario depicting R. exoculata's mating system and brooding behavior is proposed, and more generally intraspecific interactions during its benthic life stages are discussed. Expand
Extraordinary host switching in siphonostomatoid copepods and the demise of the Monstrilloida: integrating molecular data, ontogeny and antennulary morphology.
Adult monstrilloids secondarily returned to a free-living, predator-exposed mode of life and it is postulate the pressure on maintaining a functional approaching-predator detection system has progenetically delayed the suppression of the 5-point antennulary sensory array. Expand
