The recently described Dictyota cyanoloma ( Dictyotales , Phaeophyceae; Tronholm et al. 2010) is known from the Mediterranean coast of Spain ( Tronholm et al. 2010, Bárbara et al. 2015), the Adriatic, Portugal, Madeira, the Azores and Canary Islands ( Tronholm et al. 2010). Its phylogenetic affinities have been established by sequences of partial LSU rDNA, rbc L, psb A, cox 1, cox 3, and nad 1 ( Tronholm et al. 2010). Recent findings from Turkey (Taskin 2013) constitute the first records for the eastern Mediterranean so far.
The record of this taxon from Kefalonia Island reported here supports the notion that the eastern Mediterranean remains incompletely surveyed for its macroalgal diversity. DNA sequences unambiguously confirmed that the material belongs to Dictyota cyanoloma . In the eastern Mediterranean, D. cyanoloma has been previously reported from the Aegean coast of Turkey near Izmir (Taskin 2013), but not from Greek waters. This record suggests a contiguous, albeit rare distribution of this taxon in the shallow infralittoral from the Azores, Madeira and the Canary Islands, and throughout the Mediterranean, including the Adriatic to the Mediterranean coast of Turkey. Recent work ( Steen et al. 2017) has shown that this taxon is not native to Europe, but an introduction which has been present in the Adriatic as early as 1935. The same study ( Steen et al. 2017) showed that D. cyanoloma is also present in western and southern Australia.
