Caenorhabditis remanei is part of the Elegans group of Caenorhabditis species, and shares a more recent common ancestor with C. briggsae than with C. elegans. Unlike C. elegans, C. remanei reproduces through obligate crosses between XX females and X0 males. Molecular divergence with C. elegans is similar to the mouse-human distance, with saturation of neutral site turnover. C. remanei is found in temperate regions.
Some earlier studies of non-elegans species occasionally misidentified C. remanei as "C. vulgaris", or confused C. remanei with C. brenneri (itself formerly known as C. sp. 4, "CB5161", "PB2801", etc.).
