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of polychaete species in Greek waters, compiled from literature reports, online databases, museum collections and unpublished datasets.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.

“…Such damage precludes the existence of the molluscan hosts especially in the most inner part of the bay. This in turn limits the distribution of boring spionids, especially subtidal species, Dipolydora giardi and Polydora hoplura (previously recorded as Polydora uncinata in Japan: see Sato-Okoshi et al 2017;Radashevsky and Migotto 2017), which were collected mostly from subtidal gastropods in the present and previous studies (Sato-Okoshi 1999; Sato-Okoshi and Abe 2012). Large molluscs such as the scallop Patinopecten yessoensis, subtidal limpet Niveotectura pallida (as Acmaea pallida), and abalone, which spionids had often infested in the previous study (Sato-Okoshi 1999), do not distribute in or rarely inhabit Tokyo Bay.…”

An investigation of the distribution and habitat utilization of spionid polychaetes in Tokyo Bay revealed eight shellboring and 18 non-boring (interstitial, epifaunal, and infaunal) species, of these 11 species were recorded in the area for the first time. Most of the boring and interstitial species, which are associated with mollusc shells, were mainly distributed in exposed environments favoured by their host species outside Tokyo Bay. Only two boring species, Polydora websteri and Polydora haswelli preferred the enclosed waters of Tokyo Bay. Epifaunal and infaunal species were mainly distributed in the sandy and/or muddy sediment within Tokyo Bay. A widespread or localized distribution pattern within species was observed corresponding to the larval developmental mode. We concluded that habitat availability determines distribution patterns of spionid polychaetes around Tokyo Bay. Novel habitats for Boccardiella hamata, Boccardia proboscidea, Carazziella spongilla, and Polydora cornuta were recorded. Boccardia pseudonatrix, which was recorded for the first time from Japan with clear locality information, is considered to be a potential alien species.

“…2005. Heavy worm infestations have been associated with decreased host condition, weakened host shell and increased host mortality rates (Lunz 1940, Hopkins 1958, Zottoli & Carriker 1974, Lafferty & Kuris 1996, Read 2010, Sato-Okoshi et al 2017. Given these host−pest interactions, Simon & Sato-Okoshi (2015) and others have labeled P. websteri as one of the most virulent of polychaete pests to shellfish aquaculture.…”

Genetic homogeneity among geographically distant populations of the blister worm Polydora websteri

The shell-boring polychaete worm Polydora websteri, also known as blister worm, is a pest species that infests the shells of several commercially important shellfish species, including those of the oysters Crassostrea virginica and C. gigas. Historical records indicate that infestations of blister worm have impacted shellfish culture worldwide for over 100 yr. Although a lot of attention has been given to the burrowing habits of and damage created by blister worms, few studies have examined the levels of population genetic structure in this cosmopolitan species. We examined the patterns of sequence divergence at the mitochondrial cytochrome c oxidase subunit I (mtCOI) gene for individual P. websteri specimens sampled from oysters and scallops collected from shellfish farms along the US Atlantic and Gulf coasts, and Hawaii. The mtCOI sequences we obtained were aligned and compared with published sequences for P. websteri adults and larvae sampled at an oyster farm in Guangdong Province, China. We observed little genetic variation, overall, and no differentiation between populations of P. websteri, a pattern that suggests high levels of connectivity among locations. It is unlikely that natural dispersal alone can account for this lack of differentiation; rather, our results are consistent with the hypothesis that human-mediated introductions have led to genetic homogeneity across large geographic distances for this pest polychaete species.
