Proposal of Allogeochorda gen. nov., Allogeochorda subterranea comb. nov., Allostigmatella gen. nov. and four new combinations and Allosphingorhabdus gen. nov. and Allosphingorhabdus lutea comb. nov. as replacement names for the illegitimate genus names Geochorda, Stigmatella and Alterisphingorhabdus and their species
The prokaryotic genus names
Geochorda
Karnachuk
et al
. 2025,
Stigmatella
Berkeley and Curtis 1875 (Approved Lists 1980) and
Alterisphingorhabdus
Wang
et al
. 2025 are illegitimate because they are later homonyms of
Geochorda
Cham. & Schltdl. 1828 (a plant genus in the
Plantaginaceae
),
Stigmatella
G. Mey. 1825 (a fungal genus of uncertain position) and
Alterisphingorhabdus
Yan
et al
. 2024 (a bacterial genus in the
Sphingomonadaceae
), respectively, in violation of Rule 51b of the International Code of Nomenclature of Prokaryotes. To resolve these cases of homonymy and to maintain nomenclatural stability, we propose the replacement names
Allogeochorda
gen. nov.,
Allogeochorda subterranea
comb. nov. and
Allogeochordaceae
fam. nov.;
Allostigmatella
gen. nov.,
Allostigmatella aurantiaca
comb. nov.,
Allostigmatella ashevillensis
comb. nov.,
Allostigmatella erecta
comb. nov. and
Allostigmatella hybrida
comb. nov.; and
Allosphingorhabdus
gen. nov. and
Allosphingorhabdus lutea
comb. nov., as names replacing the illegitimate ones
