This taxon was discussed in a meeting of a Taxonomic Subcommittee of the ICSP.Publication:
Marshall R. INTERNATIONAL COMMITTEE ON SYSTEMATIC BACTERIOLOGY, SUBCOMMITTEE ON THE TAXONOMY OF LEPTOSPIRA: Minutes of the meetings, 13 and 15 September 1990, Osaka, Japan. Int. J. Syst. Bacteriol. 1992; 42:330-334.
Leptonema Hovind-Hougen 1979 was validly published in the International Journal of Systematic Bacteriology (Int. J. Syst. Bacteriol., 1979, 29, 245-251.) which would qualify it for inclusion in the Approved Lists of Bacterial Names. The omission of this name from the Approved Lists 1980 is clearly not in accordance with the Bacteriological Code (1990 Revision) Rule 24a, Note 1.
