Stephanthus antarcticus gen. nov. et sp. nov. is described and illustrated from six specimens collected in the Antarctic Peninsula on the Polarstern cruises ANT XV/3 and ANT XIX/3. The new genus is characterised by the absence of sphincter and basilar musculature, the presence of a single strong siphonoglyph with a basal enlargement, distinct parietobasilar musculature, tentacles without acrospheres, two cycles of six pairs of mesenteries (only one of them perfect), and a deep fosse with… Expand

Figures and Tables from this paper

Halcampulactidae (Actiniaria, Actinostoloidea), a new family of burrowing sea anemones with external brooding from Antarctica
TLDR
Molecular evidence is used to establish the phylogenetic position of the new family within the order Actiniaria, a new family of burrowing sea anemones from Antarctica characterized by a novel combination of morphological features: twelve mesenteries and invaginations of the oral disc similar to glandular sacs of Oractiidae Riemann-Zürneck. Expand
Tenactis gen. nov. (Actiniaria, Haloclavidae) a new genus of sea anemones from the Gulf of California, Mexico
TLDR
A new genus and species of sea anemone from the intertidal in the Gulf of California (Mexico) is described and the combination of having a decamerous arrangement of mesenteries, single siphonoglyph, conchula and cinclides indicate this new genus belongs to Haloclavidae. Expand
A new vermiform sea anemone (Anthozoa: Actiniaria) from Argentina: Harenactis argentina sp. nov.
TLDR
This work describes an undescribed vermiform sea anemone collected on Punta Pardelas and Fracaso Beach (Peninsula Valdes, Argentina) as a new species within the genus Harenactis (family Haloclavidae), the first record of this genus in the southern hemisphere and the first report of a soft bottom-dwelling sea anEMone in the Argentine continental zone. Expand
Metapeachia schlenzae sp. nov. (Cnidaria: Actiniaria: Haloclavidae) a new burrowing sea anemone from Brazil, with a discussion of the genus Metapeachia.
TLDR
The diversity of burrowing sea anemones from Brazil is poorly known with only three species recorded, but the two valid species of Metapeachia differ in the morphology of the conchula, internal anatomy, cnidae and geographical distribution. Expand
Description of Calliactis tigris sp. nov.: reconciling taxonomy and phylogeny in hermit-crab symbiotic anemones (Cnidaria: Actiniaria: Hormathiidae)
TLDR
Taxonomy and the present evolutionary framework are reconciled to avoid defining taxonomic groups based on characters prone to convergence and formalize the synonymy of Adamsia and Calliactis and provide updated diagnoses for the valid genera Calliactsis and Paracalliactis to bring more stability to the group. Expand
Anthopleura and the phylogeny of Actinioidea (Cnidaria: Anthozoa: Actiniaria)
TLDR
It is found that Anthopleura is paraphyletic: although species of the genus cluster together, some groups also include members of genera like Bunodosoma, Aulactinia, Oulactis, and Actinia, and this paraphyly is explained in part by the discovery that acrorhagi and verrucae are pleisiomorphic for the subset of Actinioidea studied. Expand
Genera of orders Actiniaria and Corallimorpharia (Cnidaria, Anthozoa, Hexacorallia), and their type species*
TLDR
The type species, if any, for the 425 genera of the order Actiniaria and for the 19 generA of order Corallimorpharia are determined. Expand
Biogeography of Antarctic sea anemones (Anthozoa, Actiniaria): What do they tell us about the origin of the Antarctic benthic fauna?
The present study of the biogeography of the Antarctic sea anemone fauna is based on new records and redescriptions of material collected from the Weddell Sea and Peninsula Antarctica, and on anExpand
Diversity and Distribution of Actiniaria
Sea anemones (Order Actiniaria) are among the most well successful groups of animals on the planet. They are distributed along the entire planet in several environments, from pole to pole, and soExpand
The phylum Cnidaria: A review of phylogenetic patterns and diversity 300 years after Linnaeus
TLDR
This work contrasts the Linnaean perspective on cnidarian diversity with the modern, phylogenetic perspective, and details diversity at the family level, providing phylogenetic context where possible. Expand

Rosgorgia inexspectata, new genus and species of Subergorgiidae (Cnidaria, Octocorallia) from off the Antarctic Peninsula
TLDR
The new genus Rosgorgia with the new species inexspectata is placed in the family Subergorgiidae by the presence of smooth, fusiform and often anastomosing needles in the axis, wart spindles in the coenenchyme, and coelenteric cavities of polyps only present in theCoenenchies. Expand

Oractis bursifera sp. nov., an Arctic deep-sea anemone with peculiar invaginations of its oral disc (Cnidaria: Actiniaria)
TLDR
The peculiar characters of the new species confirm the extraordinary position of the genus Oractis McMurrich, 1893, and warrant the establishment of thenew family Oractiidae within the endomyarian sea anemones. Expand
Two disc-shaped deep sea Anthozoa from the Gulf of Biscay, with a survey of adaptation types in the Actiniaria
TLDR
The two Anthozoans represent a novel morphological adaptation type (Lebensform type) with their disc-shaped bodies presumably floating on the ooze-like surface of the deep sea sediment with the known adaptational types in the Actiniaria surveyed. Expand
Antarctica as an evolutionary incubator: evidence from the cladistic biogeography of the amphipod Family Iphimediidae
Abstract The modern Antarctic marine fauna is quite distinct, with levels of endemism reaching 90% at the species level and 70% at the generic level. Since the modern Antarctic waters are very coldExpand

A guideline to nematocyst nomenclature and classification, and some notes on the systematic value of nematocysts*
TLDR
Cnidocyst nomenclature is based on the structure of the tubule and its armature as viewed in the light microscopy (LM) but some errors in the interpretation of the fine structure of tubules and armature of nematocysts have been revealed. Expand
