Description:

Ventral view of the dysteriid ciliate, Trochilia minuta (Roux, 1899) Kahl, 1931. The ventral surface is flat and the dorsum is strongly arched. Ciliature is restricted to the ventral surface except for a small dorsal brush on the left anteriorly. There are four right-sided ventral kineties. The two right-most kineties arch anterior to the cytostome to terminate at the left anterior end of the cell. There are two short preoral kineties and two very short left ventral kineties at the level of the cytostome. The cytopharynx is supported by two stout nematodesmata. There are two contractile vacuoles. There is a posteroventral adhesive podite seen here projecting beyond the posterior end of the cell. The ovoid macronucleus is heteromerous .
