Caenorhabditis sp. 3 PS1010 is now Caenorhabditis angaria.

A formal description of C. angaria has been published in the January 2010 issue of Nematology. Analysis of its phylogenetic position within the Caenorhabditis genus has defined a new species group (the Drosophilae group) of equal status, but separate from, the more familiar Elegans group containing C. elegans, C. briggsae, C. remanei, and other elegans look-alikes. Meanwhile, the genome of C. angaria (as determined by next-generation Illumina sequencing and RNA-seq scaffolding) has been published in the December 2010 issue of Genome Research, along with a detailed analysis of its ~23,000 protein-coding genes (available through the WormBase Genome Browser) and ~2,700 elements of conserved non-coding DNA. This is the first genome to be published for a member of the Drosophilae group, with DNA divergence between C. angaria and C. elegans similar to that between mammals and birds.
