However, this name is illegitimate because it was not based on the name of a genus. Of the genera placed in this family, five have familial names based on them. All of these names were published by Bavendamm in the same paper and, on the basis of page priority, Thiocapsaceae, with type genus Thiocapsa, is the correct name of this family. Nevertheless, the genus Chromatium Perty, which is the type genus of Chromatiaceae Bavendamm, is the best known and most studied genus of the red sulfur bacteria. Consequently, the Judicial Commission of the International Committee on Systematic Bacteriology is asked to conserve the familial name Chromatiaceae Bavendamm over the earlier subjective synonyms Thiocapsaceae Bavendamm, Lamprocystaceae Bavendamm, Thiopediaceae Bavendamm, and Amoebobacteriaceae Bavendamm. The family Chromatiaceae Bavendamm is emended to contain the genera Chromatium Perty, Thiosarcina Winogradsky, Thiocystis Winogradsky, Thiospirillum Winogradsky, Thiocapsa Winogradsky, Lamprocystis Schroeter, Amoebobacter Winogradsky, Thiodictyon Winogradsky, Thiopedia Winogradsky, and Ectothiorhodospira Pelsh. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-21-1-15
