Recommended three-letter abbreviation: Alc. (see the file ¤ "Three-letter code for abbreviations of generic names").

Note: Imhoff et al. propose the new genera Allochromatium, ¤ Halochromatium, ¤ Isochromatium, ¤ Marichromatium, ¤ Thiococcus, ¤ Thiohalocapsa and ¤ Thermochromatium. The names Allochromatium (Gr. adj. allos, other) and Halochromatium (Gr. n. hals, salt) are from different sources but they can be homophones. Indeed, the "H" is not pronouced in some languages such in French, Spanish, Portuguese or Italian. Moreover, in Latin, the aspirated "H" has not always been used (see: Quintilian, Institutio Oratoria, Liber primus, 5: XIX, XX, and XXI). It has been employed at the beginning of the Latin civilization but lost as early as the end of the Republic (-27) even if some educated people have retained the aspirate till Aurelius Augustinus (354 - 430). Therefore, in the spoken language the names Allochromatium and Halochromatium can be a cause of uncertainty. The proposal of the name "Dissimilichromatium" (L. adj. dissimilis, different) for Allochromatium or the proposal of the name "Salichromatium" (L. n. sal, salt) for Halochromatium would allow to avoid confusion.
