Abstract

In this study, the benthic diatoms of Homa lagoon were determined between June 2006 and September 2007. Samples were collected from four selected sampling sites. The major confusion in genus Nitzschia identification is largely caused by the lack of comprehensive descriptions of nomenclatural types and undescribed variability of diagnostic features. Therefore it’s important to describe the species in sufficient detail to permit correct species recognition. For this purpose, structural details of observed in nine species of genus Nitzschia were examined. Nitzschia compressa var. balatonis (Grunow) Lange-Bertalot, Nitzschia rectirobusta Lange-Bertalot, Nitzschia vidovichii Grunow were reported for the first time from the Turkish coastal waters. Original photographs, morphological features and some information on their distribution patterns and the substratum they inhabit were also provided.
