Class: Eurotatoria
Order: Flosculariaceae
Family: Trochosphaeridae
Description:
This species is characterized by the presence of a movable caudal seta, situated at a considerable distance of at least 40 µm from the posterior end to the point of insertion. The body is notably slender and elongated, taking on a cylindrical shape. It features two long anterolateral setae and a single posterior seta, positioned ventrally and away from the terminal point. The exact point of insertion for the posterior seta may vary. A distinctive circumapical ring of cilia is observed, encircling the anterior end. The presence of two trochal discs is notable. These trochal discs also bear longer cilia. The mastax is malleo-ramate, featuring a well-developed fulcrum, a pair of rami, and a pair of manubria, with each manubrium divided into three parts. Additionally, two unci are present, characterized by numerous teeth. These morphological features collectively define this species.
