In describing a new species of pedunculate barnacle that occurs in large numbers in sulphidic seep conditions on a volcanic seamount off Lihir Island, Papua New Guinea, it has been necessary to revise the Neolepadinae and erect two new genera. Capitulum and peduncle characters distinguish the new genera from the species ofNeolepas that occur at hydrothermal vents along the East Pacific Rise. The new genus and species from Lihir Island also differs fromNeolepas osheai described from the Kermadec… 
Systematics and ecology of a new species of stalked barnacle (Cirripedia: Thoracica: Scalpellomorpha: Eolepadidae: Neolepadini) from the Pacific-Antarctic Ridge at 38° S
The adult specimens were accompanied by large numbers of juveniles and recently settled individuals, suggesting either good recruitment or slow growth, and the coating of the capitulum and stalk indicate the vent fluid was rich in heavy metals.
A new neolepadid cirripede from a Pleistocene cold seep, Krishna-Godavari Basin, offshore India
Valves of a thoracican cirripede belonging to a new species of the Neolepadidae, Ashinkailepas indica Gale sp. nov. are described from a Late Pleistocene cold seep (52.6 ka), cored in the
A new deep-sea hot vent stalked barnacle from the Mariana Trough with notes on the feeding ecology of Vulcanolepas
A new species of deep-sea neolepadid stalked barnacle, Vulcanolepas verenae sp. nov. , is described from Hafa Adai hydrothermal vent field in the Mariana back-arc basin, northwest Pacific.
Integrative Taxonomy Reveals Two New Species of Stalked Barnacle (Cirripedia, Thoracica) From Seamounts of the Western Pacific With a Review of Barnacles Distributed in Seamounts Worldwide
Integrative taxonomy indicates that stalked barnacles collected from deep-sea seamounts of the tropical western Pacific by remotely operated vehicles represent two new species belonging to the families Scalpellidae and Poecilasmatidae, respectively.
Origin and phylogeny of verrucomorph barnacles (Crustacea, Cirripedia, Thoracica)
Asymmetrical thoracican cirripedes of superfically similar ‘verrucomorph’ morphology are shown to have evolved independently three times from pedunculate ancestors, enabling barnacles to catch crawling benthic prey in deep ocean environments where food is scarce.
A new deep-sea scalpelliform barnacle, Vulcanolepas buckeridgei sp. nov. (Eolepadidae: Neolepadinae) from hydrothermal vents in the Lau Basin.
The present study describes a new species of Vulcanolepas from the Lau Basin in the South Pacific. The basal angle of the tergum of Vulcanolepas buckeridgei sp. nov. is elevated from the
Vulcanolepas scotiaensis sp. nov., a new deep-sea scalpelliform barnacle (Eolepadidae: Neolepadinae) from hydrothermal vents in the Scotia Sea, Antarctica.
A new deep-sea stalked barnacle is described from hydrothermal vents at depths of 2400-2600 metres along segments of the East Scotia Ridge and from 1400 metres in the Kemp Caldera, confirming a wide distribution in southern seas for Vulcanolepas, complementing the previous records from deep- sea vents in the Lau Basin and Kermadec Ridge in the southwest Pacific.
Phylogeography of hydrothermal vent stalked barnacles: a new species fills a gap in the Indian Ocean ‘dispersal corridor’ hypothesis
It is shown morphologically that Neolepas specimens collected from the South West Indian Ridge, the South East Indian Ridge and the Central Indian Ridge belong to the new species, and suggested that diagnostic characters in Eolepadidae should be based mainly on more reliable arthropodal characters and DNA barcoding.

A new record of the Late Cretaceous cirripede Eoverruca hewitti (Verrucomorpha, Proverrucidae) from southern Poland
Isolated valves of proverrucid cirripedes from upper lower Campanian strata exposed at Je owka, near Wolbrom (southern Poland), are shown to be conspecific with the type (and sole) species of the genus Eoverruca, E. hewitti.


Neolepas osheai sp. nov., a new deep‐sea vent barnacle (Cirripedia: Pedunculata) from the Brothers Caldera, south‐west Pacific Ocean
This new record increases the number of described Neolepas species to four, three of which are living and the other, a fossil, is however tentatively ascribed to the genus and is known in rocks of Early Jurassic age.
Vestimentiferans (Pogonophora) in the Pacific and Indian Oceans: a new genus from Lihir Island (Papua New Guinea) and the Java Trench, with the first report of Arcovestia ivanovi from the North Fiji Basin
Explorations by the German Research Vessel Sonne in the fore-arc and back-arc basins of the western Pacific Ocean have collected vestimentiferan tube worms from both warm vent and cold seep sites.
Ectosymbiosis between filamentous sulphur bacteria and a stalked barnacle (Scalpellomorpha, Neolepadinae) from the Lau Back Arc Basin, Tonga
The occurrence, in an undescribed neolepadine from the Lau Back-Arc Basin, of cirral setae that are at least twice as long as those in other vent barnacles and bear growths of filamentous bacteria.
A study of the ovigerous fraena of barnacles

Ovigerous fraena were found in most, but not all lepadomorphs, and in a primitive balanomorph, Catophragmus (Catomerus) polymerus, which demonstrates the independent origin of these two inner mantle structures.
A new sessile barnacle (Cirripedia, Brachylepadomorpha) from the Lau Back-Arc Basin, Tonga ; first record of a living representative since the Miocene

Influence of sea-floor spreading on the global hydrothermal vent fauna
ONE remarkable discovery of recent decades is the presence of hundreds of unusual species, including fourteen new families, at hydrothermal vents. These animals, unknown from other habitats, live in
Plate tectonic history and hot vent biogeography
Abstract Since the 1977 discovery of hydrothermal vents and their extraordinary fauna, vents have been discovered along mid-ocean ridges in the eastern Pacific, on the Mid-Atlantic Ridge and on the
Biogeography and Ecological Setting of Indian Ocean Hydrothermal Vents
Most organisms found at these Indian Ocean vent fields have evolutionary affinities with western Pacific vent faunas, but a shrimp that ecologically dominates Indian Ocean vents closely resembles its Mid-Atlantic counterpart.
