Description:

Goniomonas amphinema Larsen and Patterson, 1990. Cells are 3 - 9 microns long. Two flagella insert in an anterior lateral pocket, one directed anteriorly, one posteriorly. The two flagella are unequal in length. The long flagellum usually trails over the body and is slightly longer than the cell. The cells are flattened with anterior row of ejectisomes and with or without several longitudinal ridges. The row of ejectisomes is at times difficult to observe.
