The collection of this species from a 54-m depth on a sandy-mud bottom on August 2017 near Kalkan, Turkey, also represents the first report of the genus Pseudocodium from the Mediterranean. The species was previously reported from southern Japan (type locality, Okinawa), Indonesia, New Caledonia and Papua New Guinea. Oil tankers and the several permanent/semi-permanent man-made structures are the likely vectors of introduction. © 2018 Walter de Gruyter GmbH, Berlin/Boston 2018.EnglishIndonesiaJapanMediterranean SeaNew Caledonia [Melanesia]New Caledonia [New Caledonia (DPN)]Okinawa IslandOkinawa IslandsOkinawa [Okinawa Island]Okinawa [Ryukyu Islands]Papua New GuineaRyukyu IslandsTurkeyCaulerpalesChlorophytaPseudocodiumanatomydatagreen algamorphologynew recordtype localityArticle10.1515/bot-2018-0014
