New reports and description of a new species of Sabellidae (Annelida) for the Iberian Peninsula and Balearic Archipelago

Abstract

The polychaete family Sabellidae Latreille, 1825, commonly known as feather-duster worms, is characterized by a striking, usually colourful radiolar crown that emerges from self-made tubes typically composed of mucus and sediment (Rouse, 2000; Merz, 2015), with the exception of Glomerula piloseta (Perkins, 1991), which inhabits calcareous tubes. This family represents one of the most diverse and ubiquitous families worldwide, comprising around 400 species belonging to 39 genera, all marine and benthic with the exception of one freshwater genus (Capa et al. 2014; Capa & Murray, 2015). Sabellids are found in a variety of habitats from the intertidal zone to abyssal depths (Tovar-Hernández, 2009). The systematics of Sabellidae has been considered in several studies. According to many morphological studies (e.g. Knight-Jones, 1981; Fitzhugh, 1989; Nogueira et al. 2010), Fabriciinae Rioja, 1921 was considered a subfamily of Sabellidae. More recently, however, both morphological and molecular studies consider Fabriciidae as an independent family and the sister clade to Serpulidae Rafinesque, 1815 (Kupriyanova & Rouse, 2008; Capa et al. 2011; Huang et al. 2011). However, the internal relationships of Sabellidae remain unclear, and further studies are needed to better resolve the sabellid phylogeny (Capa et al. 2014). Fitzhugh (1989) contributed greatly to the systematics of the family with an exhaustive revision. However, some traditional morphological features have been reported as inaccurate for taxonomic purposes in some taxa (e.g. Capa et al. 2010; Capa et al. 2013). Taxonomic revisions for some genera exist (e.g. Knight-Jones & Perkins, 1998; Knight-Jones & Mackie, 2003), but the establishment of the species delimitation of others remains doubtful, such as Myxicola with a poorly defined taxonomy (Giangrande et al. 2015) or Bispira, which lacks apomorphies (Capa, 2008). Moreover, despite the current knowledge of the family, some species keys still use older, inaccurate descriptions. Thus, greater effort is needed in order to clarify species statuses within some genera. To date, 19 genera and 40 valid species have been reported from the waters surrounding

“…Familia SABELLIDAE Latreille, 1825 Género Acromegalomma Gil y Nishi, 2017 Acromegalomma lanigerum (Grube, 1846) Gil (2011): 818-819;Cepeda & Lattig, 2017: 14-17, fig. 9.…”

“…Este taxón ha sido frecuentemente confundido con A. lanigerum en aguas mediterráneas (Giangrande & Licciano, 2008) y la revisión de parte del material mediterráneo ibérico (Cepeda & Lattig, 2017) ha corroborado la frecuencia de estos errores de identificación. Posiblemente la distribución de A. vesi culosum esté restringida al Atlántico norte (Giangrande et al 2015), por lo que sería necesario revisar el resto del material del área mediterránea iberobalear.…”

“…El examen de gran parte del material iberobalear identificado por diversos autores como C. duneri finalmente demostró que se trataba de indi viduos incorrectamente identificados y pertenecientes a otras especies de sabélidos (Cepeda & Lattig, 2017) como Dialychone dunerificta (TovarHernández, Licciano & Giangrande, 2007) Giangrande et al 2015), aunque sería necesario examinar el material colectado en la costa medite rránea del ámbito iberobalear para confirmar o des cartar su presencia en este área.…”
