Phylogenetic relationships of C.559479 based on maximum likelihood analysis of the reduced 16S rRNA dataset. More distant outgroups have been removed and the topology rooted on Philine scabra + P. indistincta. Numbers near nodes refer to bootstrap percentages above 70%. The scale bar indicates 0.05 changes per site. Sequences are identified by accession number and species name or informal designation recorded in GenBank except those labelled P. quadripartita for which the species names have been changed for reasons outlined in the text. Accessions with an sp. number designation followed by a space and “TO” with a one or two digit designation refer to sequences from Oskars et al. (2015). Note that this article refers to the undescribed species in alphabetical rather than numerical order so that sp. 4 in GenBank is identified as sp. D in Oskars et al. (2015).
