New Gammaproteobacteria were isolated from 3rd stage fly larvae of the parasitic fly Wohlfahrtia magnifica. Phylogenetic analysis of the new isolates showed that these bacteria belong to a distinct lineage close to Ignatzschineria larvae, 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 Ignatzschineria larvae (DSM 13226T), and indicate that our isolates represent a new genus within the Gammaproteobacteria. The major isoprenoid quinone of the strains is Q8, the major fatty acids are C18 : 1 and C14 : 0, 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 Wohlfahrtiimonas chitiniclastica gen. nov., sp. nov., is proposed for this novel genus and species. The type strain is S5T (=DSM 18708T=CCM 7401T).

Abbreviations: PE, phosphatidylethanolamine; PG, phosphatidylglycerol; PS, phosphatidylserine

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain S5T is AM397063.

A transmission electron micrograph, a dendrogram based on MALDI-TOF data and the polar lipid pattern of strain S5T are available as supplementary figures with the online version of this paper.
