Table 1 in New and known Halichoanolaimus de Man, 1886 species (Nematoda: Selachinematidae) from New Zealand's continental margin

Table 1. Morphometrics (µm) of three new and one known species of Halichoanolaimus de Man, 1886 from New Zealand’s continental margin. Abbrevations = a, body length/maximum body diameter; b, body length/pharynx length; c, body length/tail length; cʹ, tail length/body diameter at level of cloacal opening or anus; cbd, corresponding body diameter; F, length of cylindrical portion of tail as % of total tail length; L, total body length; V, vulva distance from anterior end of body; %V, V/total body length × 100.*Because females lack an anus, tail length in females was measured from posterior edge of blind intestine, and the commonly used morphometric “anal body diameter” was measured at posterior edge of the blind intestine.
