Abstract
Four halophilic archaeal strains, BCD28T, BND7T, PSR21T, and PSRA2T, were isolated from coastal and inland saline soil, respectively. The 16S rRNA and rpoB' gene sequence similarities among these four strains and current species of Halomarina were 95.9-96.6% and 86.9-90.3%, respectively. Phylogenetic and phylogenomic analyses revealed that these four strains tightly cluster with the current species of the genus Halomarina. The AAI, ANI, and dDDH values among these four strains and current species of Halomarina were 65.3-68.4%, 75.8-77.7%, and 20.3-22.0%, respectively, clearly below the threshold values for species demarcation. Strains BCD28T, BND7T, PSR21T, and PSRA2T could be differentiated from the current species of Halomarina based on the comparison of diverse phenotypic characteristics. The major polar lipids of these four strains were phosphatidylglycerol (PG), phosphatidylglycerol phosphate methyl ester (PGP-Me), and four to five glycolipids. Phosphatidylglycerol sulfate (PGS) was only detected in strain BND7T. The phenotypic, phylogenetic, and genome-based analyses suggested that strains BCD28T (= CGMCC 1.18776T = JCM 34908T), BND7T (= CGMCC 1.18778T = JCM 34910T), PSR21T (= CGMCC 1.17027T = JCM 34147T), and PSRA2T (= CGMCC 1.17214T = JCM 34148T) represent four novel species of the genus Halomarina, for which the names Halomarina litorea sp. nov., Halomarina pelagica sp. nov., Halomarina halobia sp. nov., and Halomarina ordinaria sp. nov. are proposed.

Abstract
A novel archaeal strain designated as SPP-AMP-1T was isolated from saltpan soil, using the serial dilution method on a halophilic archaeal medium supplemented with ampicillin. Cells were both rod-shaped and pleomorphic in nature, non-motile, unable to produce acid from a variety of sugars or grow anaerobically with different substrates (l-arginine) and electron acceptors (DMSO, nitrate). Optimal growth was observed at 42 °C, 3.4–4.2 M NaCl and pH 7.2. Cells did not lyse in distilled water and grew in the absence of Mg2+ ions. Phylogenetic analysis based on the sequences of 16S rRNA gene, amino acid sequence of β′-subunit of RNA polymerase and 400 conserved proteins retrieved from the whole genome assemblies showed that strain SPP-AMP-1T was distantly related to any existing genera within the family
Halobacteriaceae
. MK-8 was the only quinone detected. Polar lipid analysis showed a unique combination of diethyl derivatives of phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, glycosyl-mannosyl-glucosyl diether and sulphated glycosyl-mannosyl-glucosyl diether as the major lipids. The G+C content of genomic DNA is 57.7 mol%. The phenotypic, phylogenetic and genomic data supported the concept of the novel genus status of strain SPP-AMP-1T in the family
Halobacteriaceae
for which the name Halocatena pleomorpha gen. nov., sp. nov., is proposed; the type strain is SPP-AMP-1T (=JCM 31368T=KCTC 4276T=MTCC 12579T).

Abstract
The purpose of this announcement is to effect the valid publication of the following effectively published new names and new combinations under the procedure described in the Bacteriological Code (1990 Revision). Authors and other individuals wishing to have new names and/or combinations included in future lists should send an electronic copy of the published paper to the IJSEM Editorial Office for confirmation that all of the other requirements for valid publication have been met. It is also a requirement of IJSEM and the ICSP that authors of new species, new subspecies and new combinations provide evidence that types are deposited in two recognized culture collections in two different countries. It should be noted that the date of valid publication of these new names and combinations is the date of publication of this list, not the date of the original publication of the names and combinations. The authors of the new names and combinations are as given below. Inclusion of a name on these lists validates the publication of the name and thereby makes it available in the nomenclature of prokaryotes. The inclusion of a name on this list is not to be construed as taxonomic acceptance of the taxon to which the name is applied. Indeed, some of these names may, in time, be shown to be synonyms, or the organisms may be transferred to another genus, thus necessitating the creation of a new combination.

Abstract
Halophilic archaeal strain ZS-47-ST was isolated from Zhoushan marine solar saltern, China. Cells were pleomorphic, stained Gram-negative, and formed red-pigmented colonies on agar plate. Strain ZS-47-ST was able to grow at 20-50 °C (optimum 37 °C), at 0.9-4.8 M NaCl (optimum 3.4 M), at 0.005-1.0 M MgCl2 (optimum 0.03 M), and at pH 5.5-9.5 (optimum pH 6.5-7.5). The cells lysed in distilled water and the minimal NaCl concentration to prevent cell-lysis was 5% (w/v). The major polar lipids were C20C20 and C20C25 diether derivatives of phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, phosphatidylglycerol sulfate, glucosyl mannosyl glucosyl diether, and three unidentified glycolipids. The 16S rRNA gene and rpoB' gene of strain ZS-47-ST were phylogenetically related to the corresponding genes of Halomarina oriensis JCM 16495T (98.57 and 92.94% similarities, respectively) and Halomarina salina CGMCC 1.12543T (97.96 and 93.65% similarities, respectively). The DNA G + C content of strain ZS-47-ST was 64.6 mol % (T m). The phenotypic, chemotaxonomic, and phylogenetic properties suggested that strain ZS-47-ST (=CGMCC 1.12563T = JCM 30037T) represents a new species of Halomarina, for which the name Halomarina rubra sp. nov. is proposed.
