Diphtherophora caudata Ivanova, 1958
(Fig. 3 A, E, I, L, Table 1)
The population sampled in the present study comes close to other populations representing the species (Ivanova 1958, Ghaderi et al. 2017), except in its slightly smaller body when compared to those two studies (558–633 vs. 650 and 650–720 µm) and shorter spear than the type population (15–17 vs. 20–21 µm). The present population was recovered from the rhizosphere of cherry ( Cerasus avium (L.) Moench) trees in Maragheh, East Azarbaijan, Northwestern Iran.
