Polychaetes of Greece: an updated and annotated checklist Author Faulwetter, Sarah Author Simboura, Nomiki Author Katsiaras, Nikolaos Author Chatzigeorgiou, Giorgos Author Arvanitidis, Christos text Biodiversity Data Journal 2017 5 20997 20997 http://dx.doi.org/10.3897/BDJ.5.e20997 journal article http://dx.doi.org/10.3897/BDJ.5.e20997 1314-2828--20997 Polydora ciliata (Johnston, 1838) Notes Species complex. Mustaquim (1986) and Mustaquim (1988) provided behavioural (boring and tube-dwelling) and genetic evidence of two forms present under Polydora ciliata ; morphological differences between the forms are also reported. Radashevsky and Pankova (2006) , regarding European material, assign the tube-dwelling form to Polydora ciliata and the boring form to Polydora calcarea (Templeton, 1836). The presence of Polydora ciliata in the Mediterranean was questioned by Cinar et al. (2005) and Dagli et al. (2011) ; but see also Mikac (2015) . The former authors suggest that Polydora ciliata could have been confused with Polydora cornuta Bosc, 1802 or Polydora agassizii Claparede , 1869; a Mediterranean species synonymised with Polydora ciliata by Carazzi (1893), but resurrected by Radashevsky and Hsieh (2000) . Until re-examination of the Greek material is possible, these records are retained under Polydora ciliata in this checklist.
