According to Lai et al. (2010), this species is a later heterotypic synonym of Ruegeriamobilis Muramatsu et al. 2007.Publication:

The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. Contrasting the term "chemotaxonomic" with "phenotypic" is not recommended. Using the term "phylogenetic data" (or equivalent) for sequence data is not advocated. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details.Publication:

Ruegeriapelagia is the correct name if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Ruegeria.
The phylogenetic position of this species was determined in a genome-scale analysis by Hördt et al. (2020).Publication:
