Description:

Ploeotia azurina Patterson and Simpson, 1996. Cells measure 10-16 microns, average 13.5 microns Profile ovate, dorsally convex with 7 ridges (2 forming the margins) running longitudinally or at a slightly oblique angle. Usually only 6 ridges can be seen at any time. Cells may be flattened ventrally with a mid-ventral ridge arising anteriorly at the opening of the flagellar pocket. In some cells two lateral ventral ridges may also be seen and these cells appear less ventrally flattened. Posterior flagellum 2 - 3.5 times cell length and appears thick, anterior flagellum about the same length as the cell. Posterior end of cell tapers. Cell moves by gliding, without Anisonema-like reversals.
