The fact that a previously published name existed for this plant escaped our attention. The plant we described as Brevianthus hypocanthidium M.A.M.Renner & Engel was first recognised as a new species by Váňa and Grolle, who described it under the genus Nardia as N. huerlimannii, whose type is also from New Caledonia (Váňa 1970). Placement of N. huerlimannii within Nardia was tentative, neither author of N. huerlimannii was particularly happy with its generic placement, though no other genus was then available for what was undoubtedly a distinctive new species. Nardia is a member of the Gymnomitriaceae within suborder Jungermanniineae (Shaw et al 2015). Brevianthus belongs to the Brevianthaceae, an ally of Lophocoleaceae and Plagiochilaceae within suborder Lophocoleineae (Crandall-Stotler & Stotler 2000).  Unfortunately, consideration of potential prior published names for Elizabeth Brown’s plant was confined to suborder Lophocoleineae; a search within Gymnomitriaceae was considered unnecessary.  The type species of Brevianthus is from Tasmania, and was originally published as Jackiella flava Grolle (Grolle 1970).  That similarities between the Tasmanian and New Caledonian plants, particularly their distinctive verrucose surface ornamentation, were overlooked is perplexing given that both species were authored or co-authored by Grolle and published in the same year (Grolle 1970, Váňa 1970).  Nardia huerlimannii was placed in the new monotypic Nardia subgenus Aponardia R.M.Schust. by Schuster (2002), and though he too missed affinities with Brevianthus, he did state “I remain extremely skeptical that this can be retained in Nardia…” (Schuster 2002 p 360).  Nardia subg. Aponardia was raised to generic rank, so removing N. huerlimannii from Nardia, by Váňa et al. (2012).  Here we tranfer Aponardia huerlimannii to Brevianthus and provide the new combination.  Aponardia (R.M.Schust.) Váňa and Nardia subgenus Aponardia R.M.Schust. follow their type species into synonymy of Brevianthus as a result of this transfer.  ˇ ˇ12 Telopea 19: 11–12, 2016 Renner, Engel and VánaˇNomenclatureBrevianthus J.J.Engel & R.M.Schust., Phytologia 47: 317. 1981.
