First record of Ebria tripartita (Schumann) Lemmermann, 1899 from south of the Caspian Sea

Ebria tripartita (Schumann) Lemmermann, 1899, a non-photosynthetic flagellate algae was identified from the southern coast of the Caspian Sea in December 2012. Water temperature at the sampling time was 10 ºC The average concentration of nitrate, phosphate and silicate were 0.7, 0.1 and 1.8 mg.l ^-1 respectively at the time when species was observed. Total observed phytoplankton cells was 3 × 10^6 cells.l^ -1, of which E. tripartita constitute 2×10^3 cells.l -1 representing only 0.75% of phytoplankton community.
