Kathablepharis (kath-a-bleff-a-riss) remigera (V+rs, 1992) Clay and Kugrens, 1999. Cells are 11 to 18 microns long, not flattened and with two rows of extrusomes located ventrally. The cells are oblong or cylindrical with two flagella inserting subapically. The flagella are thick, longer than the cell, and unequal in length and may coil around the body during swimming. The anterior flagellum is about twice the length of the cell and may coil up during resting, and the posterior flagellum is about three times cell length. The nucleus lies in the middle of the cell. The cells rotate while swimming. Rarely observed.

Leucocryptos marina (Braarud, 1935) Butcher, 1967. Cells are 5-7 x 10-20 microns Asymmetrical, droplet-shaped cell with two thick, subequal flagella, about as long as the cell and inseted subapically. One or two, ventral and longitudinal rows of 1-5 large extrusomes are visible in the light microscope. There is a central nucleus. When swimming one flagellum coils around the anterior, while the other trails. The flagellate is propelled rapidly forwards, spiraling around its axis.

Kathablepharis (kath-a-bleff-are-is) is a kethablepharid flagellate. Recently, the genus Leucocryptos has been regarded as referring also to the same organisms, and so is now an obsolete name. With two long thickened flagella inserting subapically, and with a line of refractile extrusomes running along the ventral face of the body. Usually eat protists and detritus. Phase contrast.

Kathablepharis observed in freshwater sediments in the vicinity of Broome, Western Australia in September 2003. This image was taken using differential interference contrast optics. This work was supported by the Australian Biological Resources Study.
