Fig. 4. 1, 2 in Heterotrophic Flagellates from Freshwater and Soil Habitats in Subtropical China (Wuhan Area, Hubei Province)

Fig. 4. 1, 2 – Petalomonas minuta (small cell with single anterior flagellum and longitudinal groove); 3, 4 – P. pusilla (small cell with single anterior flagellum and truncate anterior end); 5–7 – Phalansterium sp. (colonies of unikont spherical cell surrounded by mucilage); 8–12 – Phyllomitus apiculatus (cells with visible flagellar pocket, two heterodynamic flagella, anterior flagellum curves back over the rostrum (8), big food vacuoles), (12) whole mount (TEM); 13, 14 – Protaspa simplex (gliding spherical cells, cell body wags in unison with the flagellar beat); 15, 16 – Pteridomonas pulex (single apical flagellum emerging from a slight depression at the top of the cell, flagellum is surrounded by 12 stiffarms, body attaches to substrate by thin stalk); 17–19 – Rhynchomonas nasuta (oval cell bears undulating proboscis and long posterior flagellum), (19) whole mount (TEM); 20, 21 – Salpingoeca amphoridium (cell with narrow neck inside amphora-like lorica); 22 – S. gracilis (cylindrical cell inside cyathiform lorica); 23–25 – S. minor (spherical cell with narrow neck inside round lorica); 26–29 – Spongomonas uvella, (spherical cells with two isokont long acronematic flagella form colonies surrounded minute granules) (29) whole mount (TEM). Scale bars: 4 µm (3, 4), 5 µm (18, 23–25, 28, 29), 6 µm (1, 2), 8 µm (5, 7, 17, 19), 10 µm (6, 8–10, 12–14, 20, 27), 15 µm (11, 15, 21, 22, 26), 25 µm (16).
