The prokaryotic generic name Frondicola Zhang et al. 2007 is illegitimate because it is a later homonym of a fungal genus name Frondicola Hyde, 1992 (Fungi, Ascomycota, Sordariomycetes, Xylariomycetidae, Xylariales, Hyponectriaceae) [Principle 2 and Rule 51b(4) of the Bacteriological Code (1990 Revision)]. It is also questionable whether the genus name can be validly published. Therefore, a new genus name, Frondihabitans gen. nov., is proposed for this taxon. As a result, a new name is proposed for the type species, Frondihabitans australicus sp. nov., to replace the illegitimate combination Frondicola australicus Zhang et al. 2007 . The type strain of Frondihabitans australicus is E1HC-02T (=JCM 13598T =DSM 17894T).
