Article
Natural and experimental wood falls harbor a rich and abundant macrofaunal community in the deep-sea. Two undescribed capitellids have been collected from wood species bundles deployed at 3,100 m at the “Deadwood 2” site in Monterey Bay and several other locations in the northeastern Pacific. Capitella blakei sp. nov. is a widely distributed deep-s...

Zootaxa has been the leading journal on invertebrate systematics especially within Annelida. Our current estimates indicate annelids include approximately 20,200 valid species of polychaetes, oligochaetes, leeches, sipunculans and echiurans. We include herein the impact of Zootaxa on the description of new annelid species in the last two decades. S...
Article
Herein we provide a taxonomic revision of Phyllodoce species from Brazil, describing 10 new species in addition to two new records, Phyllodoce longipes Kinberg, 1866 and Phyllodoce cf. madeirensis Langerhans, 1880. Phyllodoce sp. A. and Phyllodoce sp. B. are probably new but the number and condition of available specimens do not provide adequate an...
Article
A new genus and species of Hawaiian sabellid polychaete, Euchonoides moeone n. gen. et n. sp. is described. This new species has consistently been one of the most abundant polychaetes collected in Mamala Bay, Hawaii, reaching densities of 141,046 ind. m-2 and representing up to 30.6% of all polychaetes collected in that region. The species has a sm...

Introduction: Brazil has more than 8 000 km of coastline but its marine invertebrates are still poorly known. The cirratulid polychaetes have been an especially neglected group because of its challenging taxonomy. Objective: to describe a new species of Protocirrineris. Methods: In a recent survey in two of the largest Brazilian bays, Todos os Sant...
Article
Dissolution of coral rubble collected in the vicinities of a tropical ocean outfall yielded two maldanid species, one of them not previously recorded to Hawaii. The putative species Boguea cf. enigmatica was originally described from North Carolina in coral sand. The Hawaiian material fits very well the original and subsequent descriptions but it i...
Article
Abstract Intertidal, shallow subtidal and deep-water opheliids from the Hawaiian Islands, Guam in the Mariana Islands and Tutuila in American Samoa were examined and nine species are described, five of which are new. Armandia garretti sp. nov. and A. circumpapillata sp. nov. are new species proposed for previous records of A. intermedia Fauvel, 190...

A new and abundant species of Paradoneis Hartman, 1965 is described from the vicinities of a sewage outfall in Mamala Bay, Oahu, Hawaii. This species belongs to a group of at least six Paradoneis species that have three prebranchiate segments, modified notopodial lyrate chaetae from chaetiger 3, and lack additional types of modified chaetae. Parado...

La revisión de Protocirrineris de Brasil incluye un total de 3 tipos morfológicos nuevos para la zona de estudio, los cuales se encuentran caracterizadas en el presente trabajo. Las características utilizadas para la identificación de cada morfotipo fueron: posición de los filamentos tentaculares con respecto al primer par de branquias, el tipo de...
Article
Cirratulid polychaetes are abundant and diverse members of the benthic macrofauna and their particle collection mechanisms may strongly affect particle mixing and sediment grain size distribution in sediments. The feeding morphology differs in having a pair or many feeding tentacles and the ecological importance of both methods of food collection n...

Among the polychaetes, the family Cirratulidae is one of the most challenging taxonomically because most of the currently used diagnostic characters change during ontogeny. It is therefore necessary to use a combination of characters to make an accurate identification. The present work is the first of a planned revision of the genus Cirratulus from...
Article
The genus Raricirrus is characterized by the absence of feeding palps, presence of filamentous branchiae, posterior segments shorter and wider than preceding ones, and by having diverse types of chaetae, including serrate capillaries, long natatory capillaries, falcate and finely pectinate, coarsely serrate chaetae and simple curved spines. A new s...
Article
A new species of Ctenodrilus is described based on morphology, anatomy and molecular (COI and 16S) data. Phylogenetic analyses revealed that the newly described Hawaiian species is the sister taxon of the widely distributed C. serratus. Comparisons of K2P distances show distances of at least 10.9 % for 16S and 18.7 % for CO1. Morphology of C. serra...

Lacydonia Marion & Bobretzky in Marion, 1874 is the only known genus in Lacydoniidae Bergstro¨m, 1914, which is composed of small polychaetes scarcely sampled. Studies on the biology and ecology of this group are rare and most species descriptions are based on one or a few specimens. There are 13 nominal species from different parts of the world. W...
Article
Polychaetes from the Mariana Islands of Guam and Saipan have been characterized in previous studies but a thorough taxonomic study of the cirratulids has only been possible recently. Here we report on two new records, Caulleriella pacifica and Chaetozone flagellifera , and a new species, Monticellina lueldredgei , sp. nov. The species C. pacifica i...
Article
Pherecardia striata (Kinberg 1857) is a polychaete worm of the family Amphinomidae. Amphinomids are known as ‘fireworms’ due to the discomfort and itching sensation if touched. P. striata is an active predator that can swallow pieces of fish and live prey such as small crabs, shelled gastropods, and other worms and even be hand fed in aquaria (Glas...
Article
A new species, Poecilochaetus anterospinus sp. nov., is described from the east and south shores of Oahu, Hawaii. Poecilochaetus anterospinus sp. nov. is unique in the genus by the presence of noto-and neuropodial spines from chaetiger 11 to posterior segments. Neuropodial spines on anterior chaetigers are absent in all other Poecilochaetus species...

A large number multitentaculate cirratulids have been described worldwide but most are only known through the original descriptions. Type material, voucher and recently collected specimens from Brazil were revisited in order to reveal their true identity and confirm the records of widely distributed species in this region. Six species are described...

A new species of the genus Lacydonia is described from shallow waters off Oahu, Hawaii. This species is unique among its congeners by the presence of two pairs of small eyes; other lacydoniids may have either one pair of large or small eyes or no eyes at all. The description of Lacydonia quadrioculata sp. nov., brings the number of valid species wi...
Article
A survey of the capitellids from the Hawaiian Islands has yielded 16 species in seven genera, most represent new records and two species are newly described, Notodasus dasybranchoides sp. nov. and Scyphoproctus edmondsoni sp. nov. The species Capitella minima, Capitellethus cinctus and Scyphoproctus pullielloides are the most common and widely dist...

The coral reef inhabiting tubeworms from the Marshall Islands have been studied by few authors mainly by samplings in Enewetak Atoll. We report several new records of serpuline and spirorbine tubeworms from Enewetak Atoll as well as from Kwajalein, Utirik and Rongelap Atolls. Twenty-one species of Serpulinae and seven species of Spirorbinae are des...
Article
The ornamental marine trade has increased on a worldwide scale. Although Brazil is amongst the major exporters, data about this activity are underestimated. Therefore, the profile and consequences of such activity to the wild populations are not fully understood. In spite of being basically supported by fish collection, charismatic invertebrates al...

Polychaete assemblages are of special interest when studying dynamic environments such as estuaries because of their high plasticity in life strategies to cope with environmental variability. We tested the hypothesis that polychaete feeding guilds would be more related to environmental characteristics than to taxonomic composition. Polychaetes were...

Despite the existing proposals for sustainable use of the Brazilian coast, there are few mechanisms for quantification and qualification of anthropogenic impacts. For instance, the Projeto Orla (MMA, 2006) defines typologies of coastline classification, taking into account aspects of the landscape such as originality, human population density and l...
