• Synonyms:

  • Name	Kind
    Skermanella parooensis (Skerman et al. 1983) Sly and Stackebrandt 1999	homotypic synonym, validly published under the ICNP, distinct rank

• Notes:
  • ❗ Conglomeromonas largomobilis subsp. parooensis is the correct name instead if this subspecies is regarded as a separate subspecies (i.e., if its nomenclatural type is not assigned to another subspecies whose name is validly published, legitimate and not rejected and has priority) within a separate species Conglomeromonas largomobilis within a separate genus Conglomeromonas.

  • 🧍 Ben Dekhil et al. 1997 [2] propose to transfer the subspecies Conglomeromonas largomobilis subsp. largomobilis to the genus Azospirillum as Azospirillum largimobile corrig. comb. nov. and to retain the genus Conglomeromonas by elevating the subspecies Conglomeromonas largomobilis subsp. parooensis to the type species of Conglomeromonas as Conglomeromonas parooensis sp. nov. However, the new species Conglomeromonas parooensis and the emendation of the genus Conglomeromonas have not been validly published. Moreover, according to Rule 37a(2) "Retention of a name in a sense which excludes the type can only be effected by conservation and only by the Judicial Commission (see also Rule 23a)". Publication: Ben Dekhil S, Cahill M, Stackebrandt E, Sly LI. Transfer of Conglomeromonas largomobilis subsp. largomobilis to the genus Azospirillum as Azospirillum largomobile comb. nov., and elevation of Conglomeromonas largomobilis subsp. parooensis to the new type species of Conglomeromonas, Conglomeromonas parooensis sp. nov. Syst. Appl. Microbiol. 1997; 20:72-77.
  • 🧍 However, Skermanella parooensis is a new combination [Skermanella parooensis (Skerman et al. 1983) Sly and Stackebrandt 1999] not a new species [4]. Publication: Anonymous. Notification list. Notification that new names and new combinations have appeared in volume 49, part 2 of the IJSB. Int J Syst Bacteriol 1999; 49:937-939.
  • 🧍 Conglomeromonas largomobilis subsp. parooensis Skerman et al. 1983 is not closely related to Conglomeromonas largomobilis subsp. largomobilis Skerman et al. 1983 [1, 2], not closely related to Azospirillum lipoferum (Beijerinck 1925) Tarrand et al. 1979 (Approved Lists 1980) [2], and Conglomeromonas largomobilis subsp. parooensis is phylogenetically distant and positioned outside the radiation of the majority of Azospirillum, including the type species [2].
