It is named ‘perrarus’, from Latin prefix ‘per-’ meaning very and ‘rarus’ meaning rare, indicating its low abundance in the environment.\nBrief description. Planktophila perrarus MRE-203 (ENA accession number GCA_965268015) was isolated from the epilimnion (0.5m depth) of Římov Reservoir, Czech Republic (date: 2021-11-01) and it is the only isolated representative of the species. It has a complete circular genome with a size of 1,318,636 bp, a GC content of 48.28%, and a coding density of 95.4%. It encodes one rRNA operon and 38 tRNA genes. It encodes for both actinorhodopsin and heliorhodopsin, as well as the capacity to de novo synthesize retinal. It is extremely rare in the environment and in low abundances; recruitment analysis in \u003e1700 metagenomes showed that it was never found with a coverage per Gb higher than 1. In low abundances, it was recovered from Lake Ontario (USA), the coast of the Baltic Sea and the hypolimnion of Římov Reservoir (Czech Republic). The closest relative is Planktophila hypolimnetica MRH-37, with whom shared an average nucleotide identity of 75.95%.
