Proposal of Novosphingobium mangrovisedimenti as a replacement name for the illegitimate species name Novosphingobium mangrovi Huang et al. 2023

The species epithet <i>Novosphingobium mangrovi</i> Huang <i>et al</i>. 2023 is illegitimate under Rule 51b (5) of the International Code of Nomenclature of Prokaryotes, as it is a later homonym of <i>Novosphingobium mangrovi</i> Hu <i>et al</i>. 2023. The type strains of these two species share average nucleotide identity (84.7%; <95 %) and digital DNA-DNA hybridization (21%; <70 %) values below the recommended species delineation thresholds, substantiating their positions as two distinct species. Herein, the replacement name <i>Novosphingobium mangrovisedimenti</i> is proposed, preserving the original meaning related to the isolation of the type strain from mangrove sediments.
