Cells were non-motile rods showing catalase- and oxidase-positive reactions. Growth of strain ATAX6-5T was observed at 5–35 °C (optimum, 30 °C), at pH 6.0–9.5 (optimum, pH 7.0) and in the presence of 0–6.0 % (w/v) NaCl (optimum, 2 %). Ubiquinone-10 was detected as the sole isoprenoid quinone and C18 : 1ω7c, C16 : 0 and C17 : 1 ω6c were identified as the major cellular fatty acids. Diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, sphingoglycolipid, phosphatidylcholine, an unknown phospholipid and four unknown glycolipids were detected as polar lipids. The G+C content of the genomic DNA was 60.4 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain ATAX6-5T formed a tight phylogenic lineage with Parasphingopyxis lamellibrachiae JAMH 0132T with a 100 % bootstrap value. Strain ATAX6-5T was most closely related to P. lamellibrachiae JAMH 0132T with a 96.9 % 16S rRNA gene sequence similarity. Based on phenotypic, chemotaxonomic and molecular features, strain ATAX6-5T clearly represents a novel species of the genus Parasphingopyxis , for which the name Parasphingopyxis algicola sp. nov. is proposed. The type strain is ATAX6-5T (=KACC 18993T=JCM 31719T). An emended description of the genus Parasphingopyxis is also proposed., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002215
