New were isolated from 3rd stage fly larvae of the parasitic fly . Phylogenetic analysis of the new isolates showed that these bacteria belong to a distinct lineage close to , which was originally isolated from the same species of fly. The low similarity values in 16S rRNA gene sequences (93.8–94.8 %), and differences in fatty acid profiles, RiboPrint patterns, MALDI-TOF mass spectra of cell extracts, and physiological and biochemical characteristics differentiate the isolates from the type strain of (DSM 13226), and indicate that our isolates represent a new genus within the . The major isoprenoid quinone of the strains is Q8, the major fatty acids are C and C, and the predominant polar lipids are phosphatidylglycerol, phosphatidylethanolamine and phosphatidylserine. The G+C content of the DNA of the type strain is 44.3 mol%. The name gen. nov., sp. nov., is proposed for this novel genus and species. The type strain is S5 (=DSM 18708=CCM 7401).
