Etymology:
Suda et al. (2002): Planktothricoides (Plank.to.thric.oi«des. N.L. n. Planktothrix a genus of cyanobacteria; Gr. comp. oides resembling; N.L. fem. n. Planktothricoides resembling Planktothrix Anagnostidis et Komárek).

Type species: Planktothricoides raciborskii Suda et M.M. Watanabe in Suda et al. 2002 [formerly Planktothrix raciborskii (Wolszyńska) Anagnostidis et Komárek 1988]
Descriptions:
Suda et al. (2002): The trichomes are solitary, float, are generally straight, or slightly bent near the apex and attenuated toward their ends. Occasionally, a very thin, clear sheath is observed. Cross walls are slightly constricted, or not constricted and not granulated. Many small gas vacuoles are scattered at the periphery of the cells and they are easily ruptured during observation with a light microscope when the cover slip is placed on a drop of culture. It has no phycoerythrin and no capacity
to undergo complementary chromatic adaptation. Fatty acid composition is Type 4. DNA base composition is about 44 mole % GC. This species forms a independent phylogenetic cluster from Planktothrix based on 168 rDNA sequence analysis. The type species of this genus is Planktothricoides raciborskii. The genus description is based on the data cited above.
