Halovibrio Fendrich 1989, gen. nov.
Type species: ¤ Halovibrio variabilis Fendrich 1989.
Etymology: Gr. n. hals halos, salt; L. v. vibro, to set in tremulous motion, move to and fro, vibrate; N.L. n. vibrio, that which vibrates, and also a bacterial genus name of bacteria possessing a curved rod shape (Vibrio); N.L. masc. n. Halovibrio, halophilic vibrio.
Valid publication: Validation List no. 29. Int. J. Syst. Bacteriol., 1989, 39, 205-206.

Note: Dobson and Franzmann 1996 propose to transfer ¤ Halovibrio variabilis Fendrich 1989 (the type species of the genus Halovibrio) to the genus ¤ Halomonas as ¤ Halomonas variabilis (Fendrich 1989) Dobson and Franzmann 1996, comb. nov. According to Rule 37a, bacteriologists adhering to this proposal must change the name Halovibrio to ¤ Halomonas.

→ ¤ Halomonas variabilis (Fendrich 1989) Dobson and Franzmann 1996, comb. nov.
Note:During the course of studies on halophilic, Gram-negative bacteria, a comparison of two strains of halophilic bacteria, ¤ Pseudomonas halophila DSM 3050 (type strain of the species) and Halovibrio variabilis (¤ Halomonas variabilis comb. nov.) DSM 3051 (type strain of the species) demonstrated that the characteristics of strain DSM 3050 corresponded to the original description of Halovibrio variabilis (¤ Halomonas variabilis comb. nov.) and those of DSM 3051 to ¤ Pseudomonas halophila [1].
Based on data collected, Sorokin and Tindall 2006 [2] conclude that DSM 3051 is clearly a member of the genus ¤ Halomonas, and that DSM 3050 clearly is not a member of the genus ¤ Halomonas.
In a Request for an Opinion, Sorokin and Tindall 2006 [2] propose that the following steps should be undertaken by the Judicial Comission.
(i) The type of the name Halovibrio variabilis Fendrich 1989 is to be regarded as DSM 3050, not as currently published DSM 3051.
(ii) The circumscription of the genus Halovibrio should be emended as proposed by Sorokin et al. 2006.
(iii) This would also have the effect of placing members of the genus Halovibrio outside of the genus ¤ Halomonas and would mean that the names Halovibrio variabilis and ¤ Halomonas variabilis cannot be treated as synonyms.
(iv) DSM 3051 should be recognized as the type strain of ¤ Pseudomonas halophila.
(v) The species name ¤ Halomonas variabilis (Fendrich 1989) Dobson and Franzmann 1996 is to be rejected, because it was created in the belief that Halovibrio variabilis was correctly represented by DSM 3051.
(vi) Recognition of DSM 3051 as the type strain of ¤ Pseudomonas halophila would mean that data collected for this strain indicate that it should be properly placed (at least at present) within the genus ¤ Halomonas. However, the name Halomonas halophila already exists [¤ Halomonas halophila (Quesada et al. 1984) Dobson and Franzmann 1996] and it would be necessary to create a new name (nomen novum) to reflect this taxonomic interpretation. Sorokin and Tindall propose the combination "Halomonas utahensis" nom. nov. (homotypic synonym ¤ Pseudomonas halophila) to accommodate strain DSM 3051, with the current authors (and date) being the authority of the name. The type strain is DSM 3051.
(vii) Given the special circumstances under which the data were collected and published, Sorokin and Tindall 2006 also request that the Judicial Commission recognize that the species name ¤ Halovibrio denitrificans was validly published by Sorokin et al. 2006.
