“…This seems to be consistent with results from molecular analysis, where B. serrata, as well as B. manicata and B. porifera are always separated from the other examined Bispira (see Enrichetti et al, 2022); there are some features common to both Sabella and Bispira, especially with regard to the shape of the thoracic uncini, which are typically composed of numerous rows of teeth, all similar in size. The need for a deep revision of the whole Sabellinae subfamily is firmly shared by taxonomists worldwide, as well as the necessity to find informative morphological characters for its taxonomy.…”

Due to the presence of companion chaetae on the thoracic notopodia, a feature unnoticed on the material of the original description, the species Pseudobranchiomma tarantoensis (Knight-Jones & Giangrande, 2003) and P. marmarensis (Çinar & Giangrande, 2018) are here transferred to different genera; the former to the genus Sabella Linnaeus, 1767 and the latter to Bispira Krøyer, 1856. A discussion on the boundary existing among the genera belonging to the clade Sabellinae is made, underlying the importance of the thoracic uncini shape, which shows consistency with species separation from a molecular point of view.

“…However, the mistreatment of the material from the Ehrenberg expedition leads to some uncertainties on the actual origin of the majority of the species [98]; therefore, also in this case, we prefer to consider this species as cryptogenic. Lastly, the tropical sabellid Bispira melanostigma was reported by Ben-Eliahu [41] as Sabella bipunctata Baird, 1865 (currently considered synonymous); considering the difficult taxonomy of the genus Bispira, together with the recent description of some Mediterranean species [99,100], and the absence of a description of the examined specimens and deposited material, we decided to keep this record and consider it questionable.…”

The diversity and distribution of polychaetes in the coastal area and the EEZ of the Republic of Cyprus is presented based on both the literature records and new data acquired in a wide range of environmental monitoring programmes and research projects. A total of 585 polychaete species belonging to 49 families were reported in Cyprus waters; among them, 205 species (34%) were recorded based on the literature only, 149 (26%) were new records based on our own data, and a total of 231 spp. (40%) were recorded from both the literature and new data. A total of 51 polychaete species were identified as non-indigenous; among them, 32 were confirmed as alien species, 4 were considered cryptogenic, and 15 were considered questionable as there were doubts about their identity. The Indo-Pacific Schistomeringos loveni was reported for the first time in the Mediterranean Sea, while four species already reported in the literature, namely, Bispira melanostigma, Fimbriosthenelais longipinnis Leonnates aylaoberi, and Rhodopsis pusilla, were added to the list of non-indigenous polychaetes in the Mediterranean Sea. The current work highlights the importance of implementing environmental monitoring programmes and carrying out research surveys targeting benthic macrofauna assemblages.

“…In the marine benthic environment, numerous animals function as ecosystem engineers [1,2], constructing intricate frameworks with a high degree of structural complexity that provide refuge to vagile and sessile species [3]. These structuring organisms can profoundly alter the surrounding habitat, affecting larval settlement, regulating community structure by enhancing substrate stability and sediment resuspension, and modulating the current flow velocity and the distribution and availability of resources for other species [4][5][6][7][8]. The most-studied organisms are several filter-feeding taxa such as Cnidarians (i.e., gorgonians, sea fans, bamboo, stony and black corals), massive Poriferans (i.e., sponge grounds), and other colonial invertebrates [9][10][11].…”

Nevertheless, organisms with gregarious capacities, such as for example bivalves and polychaetes, also show the same ability to build complex structures e.g., [8,[12][13][14]. In addition, species that modify sediment have received attention for their direct and indirect effects on the suitability of benthic habitat for other organisms [15,16].…”

Many sessile and tube-dwelling polychaetes can act as ecosystem engineers, influencing the physical–chemical and biological characteristics of their habitats, increasing structural complexity. Thus, they are considered structuring species. In summer of 2021, in southern Sicily (Ionian Sea), benthic assemblages dominated by Ampharetidae Amage adspersa were discovered via an ROV survey at a depth range between 166 and 236 m on muddy horizontal seafloor. Large aggregations of this species (up to 297.2 tubes m−2), whose tubes are formed from Posidonia oceanica debris, occurred alternately with tube-free areas. The area was characterized by the sporadic presence of vulnerable sea pens Funiculina quadrangularis (up to 0.08 col. m−2) and Virgularia mirabilis (up to 0.16 col. m−2), and it was possible to detect signs of trawling as well the presence of marine litter (up to 24.0 items 100 m−2). The habitat description, distribution, and density of the tubes of A. adspersa were assessed via imaging analysis. In addition, morphological diagnostic analyses were carried out on some sampled specimens and on their tubes. The acquired data shed new light on how polychaetes can exploit the dead tissues of P. oceanica, contributing to highlight interactions between benthic fauna and seagrass detritus in the marine environment and their ecological role in enhancing the spatial heterogeneity of soft areas of the Mediterranean seafloor.
