“…The division of echinoids into two broad groups according to whether their periproct opens at the apex of the test inside the apical disc (`regular' echinoids) or is displaced towards the mouth and opens within an interambulacral zone (`irregular' echinoids) has been established for almost 200 years (Latreille 1825). Amongst the irregular echinoids, those with a strongly marked bilateral symmetry and the mouth displaced towards the anterior have long been recognised as a natural group, variously termed heart urchins, spatangoids or atelostomates (e.g.…”

Phylogeny and Systematics of Holasteroid Echinoids and Their Migration Into the Deep‐sea

ABSTRACT. Holasteroids are a major clade of irregular echinoids that today is con®ned to the deep-sea, but which has a rich fossil record extending back to the start of the Cretaceous Period. A cladistic analysis of this clade, encompassing the great majority of living and fossil genera, is undertaken based on new data on test architecture. The classi®cation of the group is reviewed and a new hierarchical scheme is proposed. The highly atypical apical disc structure of pourtalesiid holasteroids is discussed and critical data for understanding its plate homologies are provided by the most primitive pourtalesiid, the Late Cretaceous Galeaster. This supports the idea that plates previously identi®ed as posterior genital plates in pourtalesiids are in fact ocular plates II and IV. An evolutionary tree for holasteroids is constructed by calibrating the cladogram against the stratigraphic record. This is then used to examine how holasteroid diversity and ecology have changed through time. Holasteroids have migrated into the deep-sea at least four times independently. Three of these lineages can be traced back to sister taxa living in deep-water continental shelf environments in the Late Cretaceous±early Tertiary, while a fourth represents a very much younger migration event, possibly Late Miocene in age.

“…Branchiomma is a large, widespread, sabellid genus of about 30 species, which are found in sheltered waters such as bays, lagoons and harbours, mainly on floating docks, dock pilings (metal, wood, concrete), floating buoys (metal and PVC) and the hulls of vessels, but also on rocks, coral crevices, sponges and molluscs (Tovar-Hernández and Knight-Jones, 2006). Wide geographical distributions of some sabellid species referred to as cosmopolitan are suspect and detailed study usually finds that more than one species with narrower distributions is involved (Tovar-Hernán-dez and Knight-Jones, 2006;Licciano and Giangrande, 2008). However, at least four species of Branchiomma have been considered as alien (Tovar-Hernández et al, 2009); these include B. luctuosum (Grube, 1870), B. boholense (Grube, 1878), B. curtum (Ehlers, 1901) and B. bairdi (McIntosh, 1885).…”

“…As a result their taxonomy is better studied and several species have been described within these genera (Tovar-Hernández, 2007;Nishi et al, 2009). The genus Branchiomma Kölliker, 1859 has only partial revisions from the Caribbean Sea (Tovar-Hernández and KnightJones, 2006) and the Mediterranean Sea (Licciano and Giangrande, 2008), and phylogenetic analyses have not been performed.…”

“…Living specimens are easily recognized due to their often colourful crown frequently projecting from the mouth of their tubes. Rioja (1923) divided the sabellids into three subfamilies based primarily on chaetal characters: Sabellinae Latreille, 1825, Myxicolinae Koch in Renier, 1847and Fabriciinae Rioja, 1923. Fitzhugh's (1989 morphology-based cladistic analysis resulted in significant changes to the previous classification of Sabellidae as it demonstrated that only the subfamilies Fabriciinae and Sabellinae could be accepted as monophyletic.…”

SUMMARY: Four new species of soft-bottom sabellid polychaetes are described and illustrated. Branchiomma costaricensis n. sp. is described from 31 m depth off Isla del Coco, Costa Rica; Dialychone arabica n. sp. from 105 m depth in the Arabian Sea; Dialychone blakei n. sp. from 487 m depth off Louisiana in the Gulf of México and Paradialychone harrisae n. sp. from 30 m depth in southern California. Branchiomma costaricensis n. sp. is characterized by having microstylodes with the median pair 1.5 times longer than neighbouring pairs, thoracic uncini with two rows of teeth above the main fang, an unspotted body and large interramal eyespots. Dialychone arabica n. sp. has the anterior peristomial ring lobe exposed beyond the collar and a pre-pygidial depression occupying eight segments. In D. blakei n. sp., the anterior peristomial ring lobe is not exposed beyond the collar, the pre-pygidial depression occupies the last four segments and the posterior segments possess thin elongate, narrowly hooded chaetae. Paradialychone harrisae n. sp. differs from the other species of the genus in having the anterior peristomial ring lobe bilobed and exposed beyond the collar, a rectangular ventral collar shield and paleate chaetae with a long mucro.Keywords: Sabellidae, Branchiomma, Dialychone, Paradialychone.RESUMEN: Cuatro nuevas especies de gusanos plumero (Polychaeta: Sabellidae) de localidades mundiales. -Se describen e ilustran cuatro nuevas especies de poliquetos sabélidos de fondos blandos. Branchiomma costaricensis n. sp. es descrita para la Isla del Coco, Costa Rica, a 31 m de profundidad; Dialychone arabica n. sp. para el Mar de Arabia a 105 m; Dialychone blakei n. sp. frente a Louisiana en el Golfo de México a 487 m y Paradialychone harrisae n. sp. para el sur de California a 30 m. Branchiomma costaricensis n. sp. se caracteriza por presentar microstilodos con el par medio 1.5X más largo que los vecinos, uncinos torácicos con dos hileras de dientes sobre el diente principal, cuerpo amaculado y manchas interramales grandes. Dialychone arabica n. sp. tiene el lóbulo del anillo peristomial anterior expuesto sobre el collar y la depresión pre-pigidial ocupa ocho segmentos. En D. blakei n. sp., el lóbulo del anillo peristomial anterior no está expuesto sobre el collar, la depresión pre-pigidial está formada por cuatro segmentos y los segmentos posteriores poseen setas extremadamente largas. Paradialychone harrisae n. sp. difiere de otras especies del género por presentar el lóbulo del anillo peristomial anterior bilobulado y expuesto sobre el collar, un cojinete ventral del collar rectangular y setas paleadas con mucro largo.Palabras clave: Sabellidae, Branchiomma, Dialychone, Paradialychone.

“…On page 111, he uses the name ''Amphibiens'' for an order containing solely ''Protees et les Sirens'' (proteids and sirenids), rendering Amphibiens de Blainville a synonym of Perennibranchia Latreille (1825). We follow de Blainville in his use of the term as a formal taxon name-in other words, as a synonym of Perennibranchia Latreille (1825).…”
