Subsequent to the publication of the above paper it has been brought to our attention that the species epithet proposed for the taxon represented by strain Ma-20T is not grammatically correct as “spirulinensis” should have been proposed as spirulinae. Moreover, in order to correct an imprecision in the formation of the genus name, we propose renaming the genus Nonhongiella as Pseudohongiella.
Therefore, we propose here the corrected name for the taxon represented by strain Ma-20T.
Description of Pseudohongiella gen. nov.
Pseudohongiella (Pseu.do.hong.i.el’la. Gr. adj. pseudês, false; N.L. fem. n. Hongiella, generic name of a bacterium; N.L. fem. n. Pseudohongiella, a false Hongiella).
The description of the genus is as given for Nonhongiella in Wang et al. (2013) Antonie van Leeuwenhoek 104:933–939.
Cells are Gram-negative, aerobic, non-spore-forming, catalase-positive, oxidase-negative, and motile rods with single polar flagellum. Major fatty acids are C18:1 ω6c /C18: 1ω7c, C16:1ω6c/C16:1ω7c, C16:0, C12:0 3-OH and C12:0. The polar lipids include phosphatidylethanolamine, three unidentified phospholipids and three unidentified polar lipids. The major respiratory quinone is Q-8. The DNA G+C content of the type species is 58 mol%. Member of the Gammaproteobacteria. The type species is Pseudohongiella spirulinae.
Description of Pseudohongiella spirulinae
Pseudohongiella spirulinae (spi.ru.li’nae. N.L. gen. n. spirulinae, of Spirulina).
The description of the species is as given for Nonhongiella spirulinensis in Wang et al. (2013) Antonie van Leeuwenhoek 104:933–939.
The description is as for the genus with the following additional properties. Cells are usually 0.73–0.8 μm in diameter and 1.24–4.26 μm long. Colonies on marine agar are pale-yellow, non-translucent, and circular with regular edges. Growth occurs at pH 6.0–10.0 and 10–43 °C in the presence of 0.5–11% (w/v) NaCl, and grows optimally at 30 °C, pH 7.5–9.0 in natural seawater medium.
Production of H2S or indole doesn’t occur. Negative for arginine dihydrolase, β-galactosidase, β-glucuronidase, utilization of urea, and reduction of nitrate.

The type strain is sensitive to sodium lactate, fusidic acid, guanidine hydrochloride, niaproof, lithium chloride, sodium bromate, potassium tellurite.
The type strain, Ma-20T (=KCTC 32221T=LMG 27470T), was isolated from a pool of Spirulina platensis cultivation, Sanya, China.
