Cell outline like a grain of barley, 21±37 Mm long, 13±17 Mm wide, ¯attened, with a ventral groove which diminishes posteriorly. With about nine longitudinal pellicular grooves on each of the ventral and dorsal faces of the cell. In some cells, the grooves are ®ne and di cult to see but in a few cells they are deeper. The anterior ¯agellum is about 1.5 times the cell length and beats freely from side to side. The trailing posterior ¯agellum is about 1.7±3.2 times the length of the cell, is thicker than the anterior ¯agellum, lies in the ventral groove, and tapers posteriorly. This species contained diatoms up to 25 Mm long and one cell had four diatoms as long as 17 Mm. The ¯agellar pocket is located in the left side of the cell and the nucleus is in the right side. This species glides smoothly, but jerks backwards when changing direction. Commonly observed. Description based on observations of 29 cells.
