Abstract :Nanoplanktic diatom species are generally overlooked in conventional microscopy analyses. Phytoplankton samples were collected from surface water of a shallow coastal region in the northeastern Mediterranean Sea and analysed with scanning electron microscopy. Two new nanoplanktic diatom species were recorded; Cocconeis sigillata Riaux-Gobin et Al-Handal and Amphicocconeis rodriguensis Riaux-Gobin et Al-Handa. In addition, Delphineis australis insert ignore into journalissuearticles values(Petit); Watanabe, Tanaka, Reid, Kumada et Nagumo, Amphicocconeis disculoides insert ignore into journalissuearticles values(Hustedt); De Stefano et Marino which was previously observed in the Mediterranean Sea was also presented here. A specimen previously recorded as Psmammococconeis cf. disculoides from Argentina waters were first time recorded in the Mediterranean Sea from the external sternum valva view in this study. Differences between this Psmammococconeis cf. disculoides species and Amphicocconeis disculoides were reported. Cocconeis cf. peltoides found in this study shows different characteristics than previously identified specimens.
