“…At least two putative cryptic species exist in the Canadian Pacific (Carr et al 2011). Records of Laonice cirrata in the Mediterranean may actually belong to Laonice bahusiensis Söderström 1920 (Mikac 2015, see Sikorski 2003 for differences between species). The former is restricted to circumpolar areas, the very similar Laonice bahusiensis , however, has a more southern distribution and is also present in the Central and Eastern Mediterranean (Sikorski 2003, Çınar et al 2014).…”

BackgroundThe last annotated checklist of marine polychaetes in Greece was published in 2001. Since then, global taxonomic progress, combined with many new species records for Greece, required a thorough review of the taxonomic, nomenclatural and biogeographic status of the national species list. This checklist revises the status of all extant polychaete species reported from the Greek Exclusive Economic Zone since 1832. The work was undertaken as part of the efforts on compiling a national species inventory (Greek Taxon Information System initiative) in the framework of the LifeWatchGreece Research Infrastructure.New informationThis checklist comprises an updated and annotated inventory of polychaete species in Greek waters, compiled from literature reports, online databases, museum collections and unpublished datasets. The list provides information on 836 species-level taxa from Greece, of which 142 are considered questionable. An additional 84 species reported in the past are currently considered absent from Greece; reasons for the exclusion of each species are given. Fourteen species are reported here for the first time from Greek waters. At least 52 species in the present list constitute in fact a complex of cryptic or pseudo-cryptic species. Forty-seven species are considered non-native to the area. In addition to the species-level taxa reported in this checklist, eleven genera have been recorded from Greece with no representatives identified to species level. One replacement name is introduced. For each species, a comprehensive bibliographic list of occurrence records in Greece and the synonyms used in these publications are provided as supplementary material. Where necessary, the taxonomic, nomenclatural or biogeographic status is discussed. Finally, the findings are discussed in the wider context of Mediterranean polychaete biogeography, taxonomic practice and worldwide research progress.

“…These four species also can be distinguished by the more anterior occurrence of sabre chaetae, which ranges from chaetiger 10 to chaetiger 13 (for L. nuchala this information is lacking in the original description), their shorter caruncles, which never extend further than chaetiger 14, and by their occipital tentacle, which are digitiform instead of rudimentary, except for L. appelloeW that also bears a poorly developed one. A more similar species is L. norgensis (Sikorski 2003 (Hartman 1978;Blake 1983), and the sabre chaetae that appear in chaetigers 11-13 (Radashesky and Lana 2009). On the contrary, the second one do not belong to the same group of species, since it only bears two rows of capillaries in the fascicles of the anterior part of the body (Hartman 1953;Blake 1983).…”

“…Laonice vietezi diVers from these species by more posterior start of neuropodial pouches. Thus, in L. appelloeW, they Wrst appear in chaetiger 7 (Sikorski 2003), in L. blakei in chaetiger 3 (Sikorski 2003), in L. nuchala in chaetigers 7 or 8 (Blake 1996) and in L. macioleckae in chaetigers 6 or 7 (Aguirrezabalaga and Ceberio 2005). These four species also can be distinguished by the more anterior occurrence of sabre chaetae, which ranges from chaetiger 10 to chaetiger 13 (for L. nuchala this information is lacking in the original description), their shorter caruncles, which never extend further than chaetiger 14, and by their occipital tentacle, which are digitiform instead of rudimentary, except for L. appelloeW that also bears a poorly developed one.…”

“…Since most species diagnoses rely on combination of morphometric characteristics, many misidentiWcations occurred in the past resulting in dubious geographical ranges for supposedly cosmopolitan species. However, recent regional revisions (Sikorski 2003;Aguirrezabalaga and Ceberio 2005;Radashevsky and Lana 2009) are clarifying this problem, a trend that can be expected to continue with further research.…”

During the Antarctic summers of 2002-2003 and of 2005-2006, the Spanish BENTART cruises were conducted to the Bellingshausen Sea (Western Antarctica), aiming to study its benthic communities, from depths ranging from 100 to 2,000 m. To achieve it, 30 stations were selected; each one was surveyed in such a way that the infaunal, epifaunal and suprabenthic components of the communities were suYciently characterized. As a part of the study, some spionid individuals were identiWed as belonging to a new species of the genus Laonice Malmgren, 1867. The new species belongs to a group within the genus that is characterized by the presence of more than two rows of very numerous capillary chaetae in both noto-and neuropodial fascicles of anterior part of the body. However, it can be readily distinguished from the rest of species within the group by the posterior position in which neuropodial pouches appear (chaetiger 16 or 17) and by the caruncle reaching posteriorly chaetiger 19. In addition, other remarkable features of the new species are the short and triangular occipital tentacle, the rudimentary eyes, the hooded neuropodial hooks Wrst appearing in chaetigers 34-37 and the sabre neurochaetae Wrst occurring in chaetigers 20-27.
