“…The monophyly of Eunice and most of its taxonomically informal groups was rejected in the present results: they were paraphyletic in all MPT (Figs 9, 10A, B). The group bearing dark unidentate hooks (group D), represented by Eunice fucata Ehlers, 1887 and Eunice sebastiani Nonato, 1965, was the only informal subgroup monophyletic in some unconstrained MPT. The monophyly of all other informal groupings required the trees to be between three and eight steps longer than the MPT (Table 5).…”

Species of Eunice are distributed worldwide, inhabiting soft and hard marine bottoms. Some of these species play significant roles in coral reef communities and others are commercially important. Eunice is the largest and most poorly defined genus in Eunicidae. It has traditionally been subdivided in taxonomically informal groups based on the colour and dentition of subacicular hooks, and branchial distribution. The monophyly of Eunice and of its informal subgroups is tested here using cladistic analyses of 24 ingroup species based on morphological data. In the phylogenetic hypothesis resulting from the present analyses Eunice and its subgroups are paraphyletic; the genus may be divided in at least two monophyletic groups, Eunice s.s. and Leodice, but several species do not fall inside these two groups. Most of the traditional characters used in the taxonomy of Eunice are homoplasies; however, characters used for the first time in this study, such as certain jaw characters and characters derived from a close examination of chaetal variation along the body, are promising sources of phylogenetic signal. © 2007 The Linnean Society of London, Zoological Journal of the Linnean Society, 2007, 150, 413–434.

“…Eunice sebastiani Nonato, 1965, is currently regarded as an endangered species (D.O.U., 2004) because of its widespread use as fish bait (Amaral & Jablonski, 2005). This species was described by using large specimens collected at Araçá beach, São Sebastião, in south-east Brazil.…”

“…This species was described by using large specimens collected at Araçá beach, São Sebastião, in south-east Brazil. Nonato (1965) examined ten specimens and designated one complete specimen as type material; it was 208 cm long and 2 cm wide in the anterior region. He stated that the new species resembled E. aphroditois (Pallas, 1788), and E. roussaei de Quatrefages, 1866, but that it could be distinguished by the different shape of anterior and median notopodial cirri, and by the form of the maxillary apparatus.…”

“…The comparative study of materials belonging to these species has allowed us to have a better understanding of the morphological differences and now we regard them as distinct species. Furthermore, the examinations of these specimens allowed us to re-evaluate some features described by Nonato (1965), and Fauchald (1992) to have a better understanding of the species. Herein, we provide complete descriptions and illustrations for both species.…”

In a series of studies on eunicids, there were explicit or implicit indications that Eunice riojai described from the north-western Caribbean Sea, and Eunice sebastiani described from south-east Brazil, were synonyms. This was based upon a then recent monograph on the genus, and on the fact that some specimens were found in drifting wood which would explain the large geographical range. The study of some large specimens of E. sebastiani, collected at the type locality, shows that there are several relevant morphological differences between the two species and thus both species names must be regarded as distinct. In fact, E. sebastiani is unique in the genus because their maxillae V are bidentate. Furthermore, herein we re-describe these two species and re-evaluate some morphological features described in previous studies.

O conceito de que a temperatura constitui um fator limitante, essencial na distribuição, tem sido amplamente aceito. No entanto, fixar áreas limítrofes e distinguir conjuntos faunísticos com precisão, tem se mostrado extremamente diffcil. Uma análise dos numerosos estudos sôbre a oceanografia do Atlântico Sul e da costa brasileira, acompanhada de uma revisão cronológica da literatura sobre a zoogeografia dessa região, foi efetuada por PALÁCIO (1982).No litoral do Estado de São Paulo, a região de Ubatuba é uma das mais estudadas, havendo um razoável número de trabalhos sobre a sistemática e a ecologia de anelídeos poliquetos de substrato mole:
