Deutonura iranica

Description. General. Body length (without antennae): holotype: 1.05 mm. Colour of the body white. 2 + 2 large black eyes, in a typical arrangement for the genus (Fig. 63). Chaetal morphology. Dorsal ordinary chaetae of five types: long macrochaetae (Ml), short macrochaetae (Mc), very short macrochaetae (Mcc), mesochaetae and microchaetae. Long macrochaetae relatively thin, arc-like or straight, narrowly sheathed, feebly serrated, apically sharply pointed (Figs 63, 68 - 70). Macrochaetae Mc and Mcc morphologically similar to long macrochaetae, but much shorter (Figs 63, 68). Mesochaetae similar to ventral chaetae, thin, smooth and pointed. Microchaetae similar to mesochaetae, but clearly shorter. S-chaetae of terga thin, smooth and short, shorter than nearby macrochaetae (Figs 63, 68, 71). Antennae. Typical of the genus. Dorsal chaetotaxy of Ant. III-IV as in Fig. 64 and Table 17. S-chaetae of Ant. IV long and relatively thin, S 3 notably longer than others, sensillum sgd of medium size and straight (Fig. 64). Apical vesicle distinct, trilobate. Ventral chaetotaxy of Ant. III-IV as in Fig. 65 and Table 17. Mouthparts. Buccal cone relatively long and narrow, labral sclerifications nonogival (Figs 62, 67). Labrum chaetotaxy: 4 / 2, 4 (Fig. 62). Labium with four basal, three distal and four lateral chaetae, papillae x absent (Fig. 67). Maxilla styliform mandible thin and tridentate. Dorsal chaetotaxy and tubercles. Head without granular area between chaetae A and B. Elementary tubercles DE and EE on head present (Fig. 63). Head without chaetae O, L 2, L 3 and So 2. Chaetae C as Mcc. Chaetae Ocp notably shorter than Ocm. Chaetae De 2 on head as Mcc (Fig. 63). Th. I with tubercles Di and De not fused. Chaetae Di 3 on Th. II-III connected with tubercle Di. On Th. III, chaetae De 2 slightly longer than De 3 (Fig. 63). On Abd. I-III, chaetae De 2 longer than De 3 (Fig. 68). Cryptopygy present and strongly developed, Abd. VI invisible from above (Fig. 68). Ventral chaetotaxy. On head, groups Vea, Vem and Vep with 4, 3 and 4 chaetae, respectively. Group Vi on head with 6 chaetae (Fig. 67). Tubercles L on Abd. III and IV with 4 and 6 chaetae, respectively (Fig. 66). On Abd. IV, furca rudimentary without microchaetae. On Abd. V, chaetae Vl and L' present. Legs. Chaetotaxy of legs as in Table 18. Claw without internal tooth. On tibiotarsi, chaeta M present and chaetae B 4 and B 5 of medium size and pointed.

Diagnosis. Habitus typical of the genus Deutonura. Dorsal tubercles present and well developed. 2 + 2 large pigmented eyes. Buccal cone relatively long and narrow, labrum without ogival sclerifications. Head without chaetae O, So 2, L 2 and L 3. Tubercles Cl and Af separate. No granular area between chaetae A and B on head. Tubercles De on Th. II and III with 3 and 4 chaetae, respectively. Tubercles Di on Abd. V bilobed. Cryptopygy strongly developed.

Etymology. The species name refers to the country of its collecting.
