Abstract
The recently proposed genus Allomuricauda Deshmukh and Oren 2023 is illegitimate because it includes the type species of the genera Flagellimonas Bae et al. 2007 and Spongiibacterium Yoon and Oh 2012, contravening Rule 51b(1) of the International Code of Nomenclature of Prokaryotes. As Flagellimonas Bae et al. 2007 is the earlier described genus, we here reclassify 36 species earlier described as belonging to the illegitimate genus Muricauda as species of Flagellimonas. We also present an emended description of the genus Flagellimonas.

Abstract
A Gram-stain-negative, aerobic and non-motile rods strain, designated as strain 2012CJ39-3T, was isolated from a marine sponge, Myxilla rosacea, collected on Chuja Island, Republic of Korea. Optimal growth of strain 2012CJ39-3T was observed at 25 °C, pH 7.0 and in the presence of 2.0-3.0 % (w/v) NaCl. Strain 2012CJ39-3T contained menaquinone-6 as the respiratory quinone, iso-C15 : 1 G, iso-C15 : 0, and iso-C17 : 0 3-OH as the predominant fatty acids, and phosphatidylethanolamine, an unidentified phospholipid, an unidentified glycolipid, three unidentified aminolipids and nine unidentified lipids as major polar lipids. The genomic DNA G+C content was 38.4 mol%. Results of phylogenetic analyses based on the 16S rRNA gene and whole-genome sequences revealed that strain 2012CJ39-3T formed a distinct phyletic lineage in the genus Muricauda. Strain 2012CJ39-3T was most closely related to Flagellimonas hymeniacidonis 176CP5-101T, Muricauda spongiicola 2012CJ35-5T, Muricauda algicola AsT0115T, Muricauda flava DSM 22638T and Muricauda parva SW169T with 96.5, 96.4, 96.3, 95.8 and 95.6 % 16S rRNA gene sequence similarity, respectively. The average nucleotide identity and digital DNA-DNA hybridization values between strain 2012CJ39-3T and M. spongiicola 2012CJ35-5T, F. hymeniacidonis 176CP5-101T, M. algicola AsT0115T, M. flava DSM 22638T and M. parva SW169T were 75.6, 74.2, 78.6, 75.3 and 74.8 % and 27.4, 19.9, 36.3, 24.2 and 18.9 %, respectively. Based on these results, strain 2012CJ39-3T represents a novel species of the genus Muricauda, for which the name Muricauda myxillae sp. nov. is proposed. The type strain is 2012CJ39-3T (=KACC 22644T= LMG 32582T). In addition, Flagellimonas hymeniacidonis is reclassified as Muricauda symbiotica nom. nov.

Abstract
The prokaryotic generic names Muricauda Bruns et al. 2001 and Franklinella Bernard et al. 2022 are illegitimate because they are later homonyms of the genus names Muricauda Small 1903 (synonym of Arisaema; Tracheophyta - Liliopsida - Araceae) and Franklinella Stewart and Hendrix 1945 (a Devonian ostracod genus) and Franklinella Lenz 1973 (a Devonian brachiopod genus), respectively (Principle 2 and Rule 51b(4) of the International Code of Nomenclature of Prokaryotes). We therefore propose the replacement generic names Allomuricauda and Allofranklinella, with type species Allomuricauda ruestringensis and Allofrankinella schreckenbergeri, respectively.

Abstract
A novel strain of a member of the family Alteromonadaceae was isolated from the phycosphere of a diatom and designated as LMIT007T. LMIT007T could form milk-white, opaque, circular and smooth colonies on 2216E marine agar. LMIT007T cells were around 1.0-1.8 µm long, 0.8-1.8 µm wide, round or oval shaped and had polar flagella but were non-motile. Optimum conditions for growth were 25 °C, pH 7.0 and 6 % (w/v) NaCl. The results of 16S rRNA gene-based analysis indicated that LMIT007T had the highest similarity with the type strains Aestuaribacter halophilus JC2043T (95.95 %), Alteromonas lipolytica JW12T (95.60 %) and Alteromonas halophila KCTC 22164T (94.21 %). Furthermore, the results of phylogenetic analysis based on 16S rRNA gene sequences and of phylogenomic analysis indicated that LMIT007T could be clustered into the family Alteromonadaceae but formed a separate branch. The genome size of the strain was 2.95 Mbp and the DNA G+C content was 41.6 %. The average nucleotide identity (ANI) values of orthologous genes between LMIT007T and species of other closely related genera within the family Alteromonadaceae ranged from 66.9 to 69.2 %, and the average amino acid identity (AAI) values ranged from 60.0 to 65.7 %. The main respiratory quinone was ubiquinone-8. The major fatty acids were summed feature 3 (C16 : 1ω7c / C16 : 1ω6c) and C16 : 0. The polar lipid profile contain phosphatidylethanolamine, phosphatidylglycerol, aminolipid, two phospholipid and an unknown polar lipid. On the basis of the results of the polyphasic analysis, strain LMIT007T is suggested to represent a novel genus and species within the family Alteromonadaceae, for which the name Opacimonas viscosa gen. nov., sp. nov. is proposed. The type strain is LMIT007T (=MCCC 1K08161T=KCTC 92597T).

Abstract
In the course of screening for bacterial predators, a Gram-stain-negative, non-flagellated, gliding, long rod-shaped, and yellow-pigmented bacterium, designated strain HICWT, was isolated from coastal seawater of China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain HICWT represented a member of the genus Muricauda and showed the highest sequence similarity to M. aquimarina JCM11811T (98.8%) and M. ruestringensis DSM13258T (98.1%). The average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between strain HICWT and M. aquimarina JCM11811T were 79.2% and 34.1%, respectively. NaCl was required for growth. Optimum growth occurred at 25-30 °C, 2.0-3.0% (w/v) NaCl with pH 7.0. Strain HICWT showed some similar characteristics to the nonobligate bacterial predators, and the cells can attach to the prey cells. Strain HICWT contained MK-6 as the predominant respiratory quinone and had iso-C15:0, iso-C15:1 G, and iso-C17:0 3-OH as the major cellular fatty acids. The polar lipids contained phosphatidylethanolamine (PE), three unidentified phospholipids (PL1-PL3), one unidentified amino lipids (AL), and three unidentified polar lipids (L1-L3). The genome size of strain HICWT was approximately 3.8 Mbp, with a G + C content of 41.4%. Based on the polyphasic evidence, strain HICWT is proposed as representing a new species of the genus Muricauda, for which the name Muricauda chongwuensis sp. nov. is proposed. The type strain is HICWT (= JCM 33643 T = MCCC 1K03769T).

Abstract
An aerobic, Gram-stain-negative, rod-shaped and non-motile strain (XY-359T) was isolated from the mouth of a marine invertebrate Onchidium species from the South China Sea. It grew at pH 6.0-8.5 (optimum, pH 7.5), at 15-37 °C (optimum, 30 °C) and in the presence of 0.5-4.5 % (w/v) NaCl (optimum, 2.5 %). It could not hydrolyse Tweens 20, 40, 60 or 80 and no flexirubin-type pigments were produced. The major polar lipids were phosphatidylethanolamine, one unidentified aminolipid, six unidentified phospholipids and two unidentified polar lipids. The major fatty acids were iso-C17:0 3-OH, iso-C15:1 G and iso-C15:0 3-OH. The respiratory quinone was MK-6. Strain XY-359T showed the greatest degree of 16S rRNA sequence similarity to Flagellimonas algicola AsT0115T (96.54 %), followed by Muricauda flava DSM 22638T (96.27 %). Phylogenetic analysis based on 16S rRNA gene sequences and 31 core genes indicated that strain XY-359T belongs to the genus Muricauda. The genome size of strain XY-359T was 4 207 872 bp, with 39.1 mol% of DNA G+C content. The average nucleotide identity and digital DNA-DNA hybridization values between strain XY-359T and F. algicola AsT0115T were 74.58 % and 18.5 %, respectively, and those between strain XY-359T and M. flava DSM 22638T were 74.2 % and 18.3 %. The combined phenotypic, chemotaxonomic and phylogenetic data suggest that strain XY-359T represents a novel species of the genus Muricauda, for which the name Muricauda onchidii sp. nov. is proposed. The type strain is XY-359T (=MCCC 1K03658T =KCTC 72218T). Moreover, based on the proposal of nesting Spongiibacterium and Flagellimonas within Muricauda by García (Validation List No. 193) and the analyses of phylogenetic trees and average amino acid identities in this study, the transfers of F. algicola, F. pacifica and F. maritima to the genus Muricauda as Muricauda algicola comb. nov., Muricauda parva nom. nov. and M. aurantiaca nom. nov., respectively, are proposed, with an emended description of the genus Muricauda.
