Flamella sp. ( fig. 4 View Fig )
The species belongs to the FLamellian morphotype. Locomotive shape is FLattened and semicircular. Anterior edge of hyaloplasm is uneven and chaotically forms numerous short subpseudopodia, thin or conical. Lateral hyaloplasm also can produce subpseudopodia. Cytoplasm contains several contractile vacuoles.This amoeba is capable of rapid locomotion. Posterior part of the cell is as a rule concave, rarely convex, usually with numerous short filaments. Amoebae of the genus Flamella are able to encyct ( Page, 1988; Page, Siemensma, 1991) though we did not observe this in the cultures. Cell length is 30–55 μm, width is 50–70 μm, L/B ratio is 0.4–1.2. There is a single nucleus 4.8–9.0 μm in diameter.
Assignment of observed amoebas to the genus Flamella is confirmed by the complex of above mentioned morphological features, the presence of the semi-circular locomotor form, the wide frontal zone of hyaloplasm, which creates subpseudopodias, and formation of the adhesive filaments on the posterior end of cell ( Michel, Smirnov, 1999); for the definitive identification electron microscopy and cyst survey are needed.
Distribution: species of the genus Flamella occur in Europe and North America ( Page, Siemensma, 1991).
Habitats: we found representatives of the genus in the rivers (River Guyva of Zhytomir and Andrushivka cities; River Kam’yanka near Zhytomir city, Lopatychi village, Olevsky District, and Velyky Lug village, Chervonoarmiysky District of Zhytomir Region; the river near Perga village, Zdolbunivsky District and near Groziv village, Ostrozky District of Zhytomir Region), lakes (Pedynka village, Lyubarsky District of Zhytomir Region; Chevel village , Staro-Vyjivsky District of Volyn Region), bogs ( Berezivka village , Zhytomir District ; Galiyivka village , Vel. Korovytskogo District of Zhytomir Region; Chevel village , Staro- Vyzhyvsky District of Volyn Region) and drainage canal near Ostrog city of Rivno Region.
