“…Capa and Murray (2009) provided a good synthesis of the form and development of the dorsal margins of the collar, and the chaetal shape, describing an additional feature present in the peristomium (keel); in addition, the presence of dorsal lappets in the collar and the shape of abdominal chaetae were considered taxonomically discriminant features. The variation of the collar margin was formalised by Tovar-Hernández and Carrera-Parra (2011) and later revised by Giangrande et al (2015). Capa and Murray (2009) also proposed a cladistic analysis to test the validity of the previous artificial classification by Knight-Jones (1997).…”

“…The genus Acromegalomma includes 37 species properly named from worldwide localities (Giangrande & Licciano 2008;Capa & Murray 2009;Tovar-Hernández & Carrera-Parra 2011;Mikac et al 2013;Giangrande et al 2015;Gil & Nishi 2017;Tovar-Hernández et al 2017). Several authors revised the taxa present in the Mediterranean basin (Giangrande & Licciano 2008;Mikac et al 2013;Giangrande et al 2015), where up to now eight species have been reported: Acromegalomma vesiculosum (Montagu, 1815), Acromegalomma lanigera (Grube, 1846), Acromegalomma vigilans (Claparède, 1869), Acromegalomma cfr.…”

“…Tovar-Hernández and Carrera-Parra (2011) tried to individuate a combination of morphological features regarding the shape of the collar dorsal margin, and proposed four stages of development of dorsal lappets. Later, this scheme was modified by Giangrande et al (2015) to include more intermediate steps towards the progressive reduction of dorsal lappets and dorsal pockets.…”

The genus Acromegalomma has been recently introduced as nomen novum for the polychaete genus Megalomma. Recently specimens of A. messapicum were collected from the coastal area of Civitavecchia (Tyrrhenian Sea, Italy) and re-collected from the type locality (Brindisi, Adriatic Sea, Italy) allowing us to examine additional fresh material and to add some useful morphological and biological information to the original description. The present data widens the distribution of the species. The possibility to examine several specimens of A. messapicum collected in different areas allowed us to state with certainty the absence of variability as concerns both the distribution of the radiolar eyes and the collar shape. The new findings revealed a colouration pattern present in the thorax and in the branchial crown, as well as the presence of large pygidial eyes previously not reported. Specimens have very broadly hooded chaetae, especially at the beginning of the abdomen, becoming more slender and therefore narrowly hooded, proceeding towards the end of the abdomen. This could explain the incorrect statement in the original description, of the presence of narrowly hooded abdominal chaetae as characterising A. messapicum. The present data also allowed some biological observations. Acromegalomma messapicum is gonocoric with eggs measuring about 120 mm in diameter. Most of the specimens were collected in cold months but ripe specimens were found in warm months. In addition a scheme of groups of Acromegalomma species modified from that previously proposed by different authors is given, where some taxa have been moved to different groups on the basis of a new interpretation of the collar features.

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

Non-indigenous polychaetes along the coasts of Italy: a critical review

et al. 2020

Non-indigenous species (NIS) represent one of the most relevant threats to biodiversity, ecosystem functioning and human activities, and their occurrence and spread have been the subject of numerous works and revisions. However, the information available is rather confused for several taxa, including polychaetes, which are characterised by having a high number of cryptogenic and questionable species. This work aims at providing a revised checklist of alien polychaetes occurring along the coasts of Italy, based on the examination of newly collected and deposited material and on the critical analysis of published and gray literature, and whenever possible on the re-examination of historical material. Of the 86 polychaete species reported as NIS in Italian waters, 25 are confirmed as alien species, while 3 are cryptogenic, and 40 should be considered questionable. Finally, 18 species were excluded from non-indigenous species checklists, either because they are native, or because they represent misidentifications of other species. The high number of cryptogenic and questionable species points at the need of molecular studies and taxonomic revisions for the majority of polychaete taxa reported as NIS, in order to clarify their taxonomy, origin, introduction pathways and spreading patterns.
