Dinenympha fimbriata

Pyrsonympha minor

Description: They are pyriform or lanceolate. These cells have four equally spaced flagellar cords, eight if they are about to divide, with flagella hanging free from each of the flagellar cords. They range in size from 75-140 micrometers in length to 25-45 micrometers in width. They are often found with wood fragments and bacteria within the cytoplasm. They have an axostyle that is attached at the anterior portion of the cell and articulates within the cytoplasm.

Trichonympha agilis

The relative abundance of T. agilis are considered and indicator species of in R. virginicus (19%) and is found in less than 7% in R. flavipes and R. hageni (Lewis and Forschler 2004b). Also reported from R. virginicus (Yamin 1979) and R. hageni (Lewis and Forschler 2004b). Description: They range is size from 55-115 micrometer in length to 22-45 micrometers in width. The body is fusiform, pyriform or lanceolate with an anterior rostrum. These cells have many attached flagella at the anterior portion of the body and are vigorous swimmers. They are often seen with wood fragments within the cytoplasm.
