“…Traditionally, M. sanguinea has been regarded as a widespread species; but recent studies and our results show it is a morphologically distinguishable species complex that can be differentiated based on features not previously studied in detail, e.g. form and number of pectinate chaetae and hirsute shaft of spinigers (Hutchings & Karageorgopoulos 2003;Lewis & Karageorgopoulos 2008;Glasby & Hutchings 2010 and herein). In the Grand Caribbean, M. acicularum, M. nobilis and M. viridis were regarded as junior synonyms of M. sanguinea; however, we have shown that they are different and consequently reject the synonymy.…”

Thus, they redescribed the species and restricted its distribution to northern Europe.…”

As part of a study on Marphysa de Quatrefages, 1865 from the Grand Caribbean, three species regarded as junior synonyms of M. sanguinea (Montagu, 1913) were studied to clarify their taxonomic status. The examination of type and additional materials collected in the southern Gulf of Mexico and the Mexican Caribbean regions, allowed us to clarify that M. acicularum Webster, 1884, M. nobilis Treadwell, 1917 and M. viridis Treadwell, 1917 are distinct species. Therefore, the three species were redescribed and some important morphological features such as maxillary apparatus, shape of parapodial lobes, shape of ventral cirri and pectinate chaetae, among others, were described and evaluated. Furthermore, we consider that previous records of M. sanguinea for the Grand Caribbean are doubtful and it is necessary to reassess those specimens to clarify their taxonomic identity.

“…Considered cosmopolitan in the past, but Marphysa sanguinea actually comprises a complex of numerous pseudo-cryptic species (Zanol et al 2016). Hutchings and Karageorgopoulos (2003) designated a neotype based on pectinate chaetae distribution instead of branchiae and Hutchings et al (2012) encourage re-examination of all material outside the English Channel and North Sea. Recent studies have described several new species similar to Marphysa sanguinea or resurrected species from synonymy with the latter (Lewis and Karageorgopoulos 2008, Molina-Acevedo and Carrera-Parra 2015, Zanol et al 2016, Liu et al 2017).…”

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.

“…This species is recorded as a cosmopolitan species, distributed globally at temperate to tropical latitudes (e.g. Fauvel 1923, Hutchings and Karageorgopoulos 2003, Prevedelli et al 2007). However, voucher specimens for many populations do not exist or were poorly identified.…”

“…However, voucher specimens for many populations do not exist or were poorly identified. Taxonomists have recently reexamined many of these specimens, concluding that they may be a few to several different sibling species (Hutchings and Karageorgopoulos 2003, Prevedelli et al 2007, Lewis and Karageorgopoulos 2008. All literature referring to M. sanguinea and its biology should therefore be referred to with caution.…”

Summary: Ultrastructural features of oogenesis of the iteroparous and long lived eunicid polychaete Marphysa sanguinea (Montagu, 1815) from the Lagoon of Tunis were studied using both light and transmission electron microscopy methods. The ovaries consist of coelomic germ-cell clusters surrounded by a thin envelope of follicle cells derived from the peritoneum. They are attached to the genital blood vessels. Oogenesis is asynchronous; therefore, germ cells in premeiotic and previtellogenic phases are observed in one cluster. The oogenesis is of the extraovarian type. In each cluster the more differentiated oocytes detach and float free in the coelomic cavity where they undergo vitellogenesis as solitary cells. Inside the ovary, follicle cells are connected to young oocytes by intercellular bridges and data suggest that in the early stages of vitellogenesis, ribosomes, multivesicular bodies and dense bodies are transferred from the follicle cells to the oocytes through the intercellular bridges. Different morphological evidence supports the heterosynthetic (presence of endocytotic vesicles, abundant microvilli adorning the surface of the egg) and autosynthetic (proteosynthetic organelles well developed, formation of blebs by the external membrane of the nuclear envelope) origin of yolk in M. sanguinea. The cytoplasmic material of the mature oocytes is asymmetrically distributed; large lipid droplets (1.5 µm in size) and large yolk spheres (6 µm in size) occupy the vegetal pole of the oocyte while small yolk spheres (2-3 µm in size) and numerous membranous organelles (mitochondria, cisternae of endoplasmic reticulum) occupy the animal hemisphere. Spherical to elongated cortical granules up to 1.8 µm in size are located in the cortex of the mature oocytes. Finally, fibrogranular aggregates ("nuage") similar to that within the nucleus are observed in the cortical ooplasm located in the animal pole of mature oocytes. These aggregates probably come from the nucleus and represent maternal cytoplasmic determinants of embryonic cell fate. Oocytes that have completed vitellogenesis measure 250-300 µm in diameter.Keywords: Marphysa sanguinea; annelid; Polychaete; oogenesis; vitellogenesis; ultrastructure. Estudio ultraestructural de la ovogénesis en Marphysa sanguinea (Annelida: Polychaeta: Eunicida) en la Laguna de TúnezResumen: Se estudiaron las características ultraestructurales de la ovogénesis del poliqueto de la familia Eunicidae, Marphysa sanguínea (Montagu, 1815), caracterizado por ser iteróparo y presentar una largo periodo de vida vital. Los ejemplares proceden de la Laguna de Túnez y se estudiaron tanto mediante microscopía óptica como mediante microscopía electrónica de transmisión. Esta especie presenta ovarios consistentes en agrupaciones de células germinales celómicas rodeadas por una envoltura delgada de células foliculares derivado del peritoneo y unidos a los vasos sanguíneos genitales. La ovogénesis es asincrónica, por lo que se observan células germinales en fases premeióticas y previtelogénicas en cad...
