Morphometric variations in Hirschmanniella mucronata (DAS, 1960) Luc and Goodey, 1963

Stylet length, body width, V% in females and spicule length in males are the most stable characters (cv. -2-5%). Body length, tail length, length of body from head and to vulva, vaginal length, gubernaculum and bursal length, a and c values show moderate variations (c.v. 5–10). Opening of DOG, median bulb distance from anterior end, excretory pore, ‘b’ and ‘c’ values are highly variable characters (c.v. 11–16%). Body width is a more stable character than ‘a’ value, tail length than ‘c’ value and V% than distance of vulva from head end.
