Table 3. Morphometrics (μm) of Psammonema buamphida sp. nov. Abbreviations: a = body length / maximum body diameter; b = body length / pharynx length; c = body length / tail length; c’ = tail length / anal or cloacal body diameter; cbd = corresponding body diameter; L = total body length; V = vulva distance from anterior end of body; %V = V/total body length ×100.
