Remarks. The Iranian population of H. anchoryzae (Pourjam et al. 2000) closely corresponds to the original description (Ebsary & Anderson 1982). However, in Iranian specimens the female has stylet length of 18 (16–19) µm vs 16–17 µm in the original description. Males differ from the original description in some characters such as: body length (1565–2130 vs 1116–1297 µm), a (67–83 vs 45–61), c´value (6–8.4 vs 4–5.8), stylet (18–21 vs 16 µm), and spicule (39–40 vs 28–31 µm).
