Magelonidae (Annelida, Polychaeta) Do Litoral Sudeste Do Brasil

Abstract

(Magelonidae (Annelida; Polychaeta) from the southeastern Brazilian coast). A systematic survey of the Magelonidae (Annelida; Polychaeta) from the southeastern Brazilian coast (Paraná, São Paulo and Rio de Janeiro States) is presented. A total of six species are described: Magelona papillicomis Muller, 1858; Magelona riojai Jones, 1963; Magelona variolamellata sp. n.; Magelona posterelongata sp. n.; Magelona nonatoi sp. n.; Magelona crenulata sp. n.Apresenta-se um levantamento sistemático da família Magelonidae (Annelida; Polychaeta) do litoral sudeste do Brasil (Paraná, São Paulo e Rio de Janeiro), representada regionalmente por seis espécies: Magelona papillicomis Muller, 1858; Magelona riojai Jones, 1963; Magelona variolamellata sp. n.; Magelona posterelongata sp. n.; Magelona nonatoi sp. n.; Magelona crenulata sp. n. Descrições e ilustrações são apresentadas para todas as espécies, juntamente com uma chave de identificação.

The Magelonidae (Annelida: Polychaeta) from the Seychelles 2: description of four additional species, three new to science

“…Magelona mahensis n. sp. resembles three species; M. capax Hartman, 1965, M. variolamellata Bolívar andLana, 1986, and an undescribed species Magelona sp. I of Uebelacker and Jones, 1984 in exhibiting a reduction in the size of the thoracic neuropodial lamellae.…”

“…The following species all approach M. symmetrica in having sharply triangular abdominal lamellae: M. polydentata Jones, 1963, M. variolamellata Bolívar andLana, 1986 and an undescribed species, Magelona sp. I of Uebelacker and Jones, 1984. However, M. polydentata and Magelona sp.…”

Polychaete Associations in a Subtropical Environment (São Sebastião Channel, Brazil): A Structural Analysis

“…In the Brazilian coastal zone the benthic subtidal fauna has been intensively studied during the past few years especially in the south‐eastern shelf ( Lana, 1986a; Pires, 1992; Pires‐Vanin, 1993). The annelid polychaetes, for example, have been well studied, but most of these investigations have dealt with taxonomy ( e. g., Amaral, 1982 ; Amaral & Nonato, 1984; Bolivar & Lana, 1986, 1987; Camargo, 1995; Camargo & Lana, 1994, 1995a, b; Lana, 1986b, 1991; Nonato, 1965; Nonato & Luna, 1970a, b; Nonato et al, 1986 ) or are only available in an unpublished thesis.…”

Observations on the tubicolous annelidMagelona alleni(Magelonidae), with discussions on the relationship between morphology and behaviour of European magelonids

“…In general, magelonids have been reported to be relatively motile, burrowing more or less continually through sediments (Jones, 1968; Fauchald & Jumars, 1979; Mortimer & Mackie, 2014). Although some species such as Magelona polydentata Jones, 1963, Magelona variolamellata Bolívar & Lana, 1986, Magelona longicornis Johnson, 1901 (Jones, 1971), Magelona cincta Ehlers, 1908, Magelona falcifera Mortimer & Mackie, 2003, Magelona symmetrica Mortimer & Mackie, 2006 and Magelona alleni Wilson, 1958 have previously been reported to construct tubes (Mortimer et al ., 2012; Mortimer, 2017), no information on the permanency of tubes has been recorded.…”
