TABLE 2 in Two new species of Promonhystera Wieser, 1956 (Nematoda: Monhysterida: Xyalidae) from the South China Sea

TABLE 2. Morphometric measurements of all valid Promonhystera species (in µm, except a, b, c, c′ and a.b.d). Data cited from Leduc & Zhao (2023), Riemann (1966) and Wieser (1956). Abbreviations are as follows: a: the ratio of body length to maximum body diameter; b: ratio of body length to pharynx length; c: ratio of body length to tail length; c.b.d.: corresponding body diameter; c′: ratio of tail length to cloacal or anal body diameter; sp/a.b.d.: ratio of spicule length to cloacal body diameter.
