Introduction
Caenorhabditis sp. 5 is a member of the Elegans group of species, which morphologically resemble C. elegans itself and are closely grouped with it evolutionarily in Clad V (Kiontke et al., 2011). It is a gonochoristic species, requiring mating between males and females for reproduction, and the closest outgroup to the interfertile pair of hermaphroditic C. briggsae and male-female C. sp. 9.
Its geographic distribution is remarkably confined to East Asia, being commonly found in China and northern Vietnam, particularly in habitats with moist decaying vegetation. C. sp. 5 shows strikingly high molecular diversity, assayed by SNP variability (Wang et al., 2010); however, its codon usage patterns are similar to those of C. elegans (Cutter et al., 2008).
