Diagnosis:
Type species: Starria zimbabweensis Lang 1977. - Monospecific genus.
Descriptions:
Komárek (1992): Filamentous; filaments unbranched, uniserial, isopolar, solitary, short or variable in length, straight to helically twisted, more or less equally wide along the whole length, about 15 um wide and slightly torulose, without sheaths or with delicate sheaths 3 um thick following the contours of the cell; trichomes flattened and triradiate in transverse section slightly constricted at the cross walls, immotile. Cells shorter than broad, in cross section with broad arm-like projections 120 degrees apart, separated by U-shaped depressions, arms broaden somewhat toward their extremities which may be obtuse to truncate at outer edge; pigmentation is concentrated in arms. Thylakoids localized along the cell walls and more agglomerated and coiled within the protrusions. Cell content blue-green, without prominent granules and inclusions. Heterocytes and akinetes are missing.
