<p>Three reddish-pink, gram-stain-negative, motile, flagellated, short rod-shaped methanotrophs, designated BW4-1<sup>T</sup>, SPW-1<sup>T</sup>, and PHL2-19<sup>T</sup>, were isolated from wetland sediments in South Korea.
Description
All three strains possessed intracytoplasmic membranes characteristic of type I methanotrophs and grew with methane or methanol as the sole carbon and energy source. Their major fatty acids were C<sub>14:0</sub>, C<sub>16:0</sub>, and summed feature 3 (C<sub>16:1</sub>ω7c and/or C<sub>16:1</sub>ω6c).
Phylogenetic and phylogenomic analyses placed the strains within the genus Methylomonas, with Methylomonas defluvii OY6<sup>T</sup> as their closest relative. Despite sharing 99.9–100.0% 16S rRNA gene sequence similarity, the strains were differentiated by genomic and phenotypic characteristics. Pairwise average nucleotide identity and digital DNA–DNA hybridization values among the three strains were 95.0–95.9% and 60.4–66.2%, respectively, supporting their recognition as distinct species.

All three strains possessed complete pmoCAB and mmoXYBZDC clusters and pathways linking methane-derived carbon to C<sub>30</sub> and C<sub>40</sub> carotenoid biosynthesis. PmoA phylogeny supported predominantly vertical inheritance of pmoCAB, whereas the patchy distribution and phylogenetic incongruence of MmoX indicated lineage-specific gain, loss, and possible horizontal transfer of sMMO-associated genes. Ancestral reconstruction further indicated that pMMO-dependent methane oxidation and carotenoid biosynthesis were evolutionarily conserved, whereas the sMMO system was shaped by more dynamic, lineage-specific evolutionary processes.
Accordingly, the names Methylomonas sediminis sp. nov. (BW4-1<sup>T</sup> = KACC 24053<sup>T</sup> = MCCC 1K10705<sup>T</sup>), Methylomonas paludicola sp. nov. (SPW-1<sup>T</sup> = KACC 24052<sup>T</sup> = MCCC 1K10729<sup>T</sup>), and Methylomonas roseola sp. nov.
(PHL2-19<sup>T</sup> = KACC 24054<sup>T</sup> = MCCC 1K10706<sup>T</sup>) are proposed.</p>
