Capitellethus dispar (Ehlers, 1907)


Capitellethus dispar (Ehlers, 1907) 


Questionable status. Listed by Arvanitidis (2000a), subsequently included in the checklist by Simboura and Nicolaidou (2001) but in fact based on a record from the Turkish Aegean, which is considered questionable by Çınar et al. (2014). The actual first record of the species from Greece is by Akoumianaki (2004). However, this species can be confused with several species of Notomastus  Sars, 1851, based only on the thoracic chaetal formula which was traditionally used for identification. Green (2002) clarified some inaccuracies in previous descriptions of Capitellethus  and used the teeth pattern in hooks as a reliable differentiating character between these two genera. If the presence of this species in Greece can be confirmed, it should be regarded as a non-native species. Originally described from New Zealand.
