Qingshengfania soli Zhang et al. 2015 is a later heterotypic synonym of Pseudochelatococcus lubricantis Kämpfer et al. 2015.

Qingshengfania soli DSM 103870T was compared with Pseudochelatococcus lubricantis MPA 1113T to clarify the taxonomic relationship of both species because of their high phylogenetic relationship. 16S rRNA gene sequence comparisons demonstrated that these species share 100  % sequence similarity. Investigation of fatty acid patterns, substrate utilization, and matrix-assisted laser desorption/ionization-time-of-flight (MALDI-TOF) profiles displayed no striking differences between the type strains of both species. DNA-DNA hybridization between both strains showed a 95 % (reciprocal 82 %) similarity, which clearly demonstrated that both strains are members of the same species. Due to priority of publication and validation of the name, Qingshengfania soli is reclassified as Pseudochelatococcus lubricantis, based on the estimated phylogenetic position derived from 16S rRNA gene sequence data, fatty acid, biochemical data, MALDI-TOF, and DNA-DNA hybridization results.
