Polychaetes of Greece: an updated and annotated checklist Faulwetter, Sarah Simboura, Nomiki Katsiaras, Nikolaos Chatzigeorgiou, Giorgos Arvanitidis, Christos Biodiversity Data Journal 2017 5 20997 20997 373FT 46592 Orsted, 1843 Orsted 1843 Polychaeta Cirratulidae Dodecaceria CoL Animalia Dodecaceria concharum Terebellida 0 20997 Annelida species concharum  Notes Questionable status. Castelli et al. (2008)and Mikac (2015)consider the presence of the species in the Mediterranean uncertain as it may have been confused with Dodecaceria saxicola(Grube, 1855), Dodecaceria sextentaculata(Delle Chiaje, 1822), Dodecaceria fimbriata(Verrill, 1880) or Dodecaceria joubiniGravier, 1905. Several Greek specimens were examined by P.H. Gibson and differ from the northern European species; instead, different species (e.g. Dodecaceria joubini) could be present in Greece (P.H. Gibson, pers. comm. in Simboura 1996). The identification of Dodecaceriaspecies depends on reproductive characteristics ( Gibson 1978) but it is unknown which form was described by Orsted. Thus, identity of Dodecaceria concharumis confused and Orsted'soriginal species is probably not valid due to an insufficient original description and loss of type material ( Gibson 2015). Neotypes were designated by Gibson and Heppell (1995), but it is unclear whether these correspond to the original species of Orsted.
