Onuphidae (Annelida, Polychaeta) da região de Ubatuba, litoral norte do estado de São Paulo, Brasil Onuphidae (Annelida, Polychaeta) from Ubatuba, north coast of the São Paulo State, Brazil

<abstract language="eng">Ten species of onuphid polychaetes were identified from the sublitoral of Ubatuba, on the coast of the state of São Paulo, Brazil: Diopatra cuprea (Bosc, 1802); Diopatra tridentata Hartman, 1944; Kinhergonuphis difficilis (Fauchald, 1982); Kinhergonuphis fauchaldi Lana, 1991; Kinhergonuphis orensanzi (Fauchald, 1982); Kinhergonuphis tenuis (Hansen, 1882); Mooreonuphis nebulosa (Moore, 1911); Mooreonuphis pallidula (Hartman, 1965); Mooreonuphis intermedia (Kinberg, 1865); Onuphis dibranchiala Willey, 1905. A discussion on the characteristics of the species found and related species is also provided

Espécies do gênero Munida Leach (Crustacea, Decapoda, Galatheidae), distribuídas na costa do Brasil Species of the genus Munida Leach (Crustacea, Decapoda, Galatheidae) with distribution in the Brazilian coast

<abstract language="eng">The purpose of this work is to analyse the taxonomy and distributional patterns of the species of the genus Munida Leach, 1820 which occur along the Brazilian coast. The species of Munida present some peculiar characteristics, rarely found in any other marine group. They live in groups with great number of individuals (gregariousness) and with several species found together in the same population (sintopy). In addition, they exhibit a great degree of intraspeciftc variation and, paradoxally, a little variability among the species. These factors make a better understanding of the systematics of this group very difficult. In the present study the utilization of non variable characters was emphasized. As a corollary of this study, "species-complexes" were defined including groups of species morphologically very similar but yet well characterized. Sixteen species with distribution along the Brazilian coast were studied. An identification key is provided. A general discussion where the main problems on taxonomy and distributional patterns of species were analysed was done

The family Donacidae (Bivalvia: Tellinoidea) in Thai waters

The species belonging to the family Donacidae living in Thailand waters are herein revised. After an exhaustive bibliographical search, 29 nominal species were found from this area. Materials from several institutions and specimens collected during fieldwork in Phuket and the Gulf of Thailand were studied. All the type materials were illustrated and redescribed. Details of the type localities, repositories, habitats and biogeographical distribution are discussed. In addition, some collected specimens and the type materials of the valid species and synonyms are illustrated. Currently, eight valid species are confirmed as living in Thailand waters: Donax (Deltachion) spinosus Gmelin, 1791, Donax (Deltachion) semigranosus (Dunker, 1877), Donax (Dentilatona) incarnatus Gmelin, 1791, Donax (Hecuba) scortum (Linnaeus, 1758), Donax (Latona) cuneatus Linnaeus, 1758, Donax (Latona) faba Gmelin, 1791, Donax (Latona) solidus Spengler, 1798 and Donax (Paraserrula) introradiatus Reeve, 1855. The presence of Donax (Deltachion) semisulcatus Hanley, 1843, Donax brazieri Smith, 1892, Donax (Tentidonax) veruinus Hedely, 1913 and Donax victoris Fischer-Piette, 1942 in Thailand waters remains uncertain. These species have been reported in the study area in the literature, but they were not sampled during this study.Fil: Signorelli, Javier Hernan.

Anelídeos poliquetos da região de Ubatuba (SP): padrões de distribuição geográfica

<abstract language="eng">This work constitutes a systematic survey of the Annelida Polychaeta from the sublitoral of the São Paulo State coast (Ubatuba), southeast Brazil. From 105 identified species, 20 are new records for the brazilian coast. An analysis of affinity degree between the fauna of the studied region and of the adjacents biogeographic provinces shows that 25,5% of the species are endemic for the Paulista Province, 19,0% amphi-american, 17,0% cosmopolite and 16,8% amphi-atlantic. An affinity with species from the Patagonian (7,4%) and Caribbean (2,0%) Provinces is smaller than that of other authors, for the southeast Brazilian coast
