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

The species epithet Novosphingobium mangrovi Huang et al . 2023 is illegitimate under Rule 51b (5) of the International Code of Nomenclature of Prokaryotes, as it is a later homonym of Novosphingobium mangrovi Hu et al . 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 Novosphingobium mangrovisedimenti is proposed, preserving the original meaning related to the isolation of the type strain from mangrove sediments.
