( Figs 2f View Fig , 3f View Fig )
Cells are 5.5–6 μm long and ovoid with a short collar and a long stalk. The pseudopodia are symmetrical and longer than the cell. The thickened flagellum is 2–2.5 times the cell length and acronematic. The cells may attach to the substrate by the stalk and swim. Observations based on 3 colonies with 12 cells. Occurance: every month at Acı Lake, temperature 1–23.5 °C, salinity 24–67.5 psu, dissolved oxygen 3.75–13.2 mg /L.
Remarks: Choanoflagellates have been revised based on the molecular phylogenetic studies ( Carr et al. 2008, Nitsche et al. 2011). The genera of Codosigidae were placed under Salpingoecidae sensu Nitsche et al. (2011) . Generally, the observations are in accordance with those of Hibberd (1975) and Vørs (1992a). It was reported that the taxonomy of Codosiga is likely to be confused ( Vørs 1992a) with Monosiga . Codosiga botrytis includes taxa with thin and thick stalks, but is distinguished primarily by the formation of unique colonies. Single celled forms of the genera may be indistinguishable from the genus Monosiga (Leadbeater and Morton 1974) . This species was also found at marine sites in eastern North America, Denmark, Gulf of Finland, Germany and Italy ( Griessmann 1913, Norris 1965 as Codosiga pyriformis, Hibberd 1975 ; Vørs 1992a, b).
