Material examined. Korea, Gangwon-do , Yangyang-gun, Namdaecheon Stream (38°04′39″N, 128°37′55″E), 21 Oct 2017, collected by Won Je Lee.

Description. Cells are oval or globular in shape, 4.5-7.0 (avg. 5.7) μm long and rigid. The cells have a small rostrum in the anterior end ( Fig. 1m, 1o, 1q , arrowheads), behind which two flagella insert. The active anterior flagellum is short and is 0.3-0.4 times the cell length, and bends slightly ventrally. The longer posterior flagellum is 1.3-1.8 times the cell length and trails posteriorly. This species is common in freshwater habitats. This genus is morphologically similar to the genera Heteromita and Neoheteromita .

Previously reported cell length. 4-5 μm ( Hollande, 1942; Howe et al., 2009).

Habitat. Freshwater sediments, soils.

World distribution. France ( Hollande, 1942), USA ( Howe et al., 2009), Korea.

Deposition. National Institute of Biological Resources, Korea (NIBRPR0000109168).

Identifiers. Won Je Lee.
