Figs 1–7 , Tab. 1

Type material. Holotype: adult male on slide: Iran: Elburz Mts., Golestan province, near Gorgan town, Barankoh Forest [36°47’ N 56°23’ E], Carpinus betulus forest, soil, N slope, 4.09.2011, leg. A. Falahati. Paratypes: adult male, two adult females and two juveniles on slides, same data as holotype. Holotype and 2 paratypes are housed in the Department of Evolutionary Biology and Ecology, Wrocław University, Poland, 3 paratypes in the collection of the second author.

Etymology. The species name refers to the historic name of Iran.

Diagnosis. Habitus typical of the genus Cryptonura . Colour of the body bluish-gray, 2 + 2 eyes darkly pigmented. Dorsal tubercles present and well developed, triangular in shape. Buccal cone rather long, labrum ogival. Head with chaetae A, B, C and E. Chaeta O absent. Tubercles Af and Cl fused. Tubercles Dl and (L+So) on head with 5 and 8 chaetae respectively. Tubercle Di on th. I with 1 chaeta. Tubercles De on th. II and III with 3 and 4 chaetae respectively. Tubercles L on abd. III and IV with 4 and 6 chaetae respectively. Macrochaetae Ml relatively long, Ml Di 1 of abd. IV longer than axial diameter of the abdomen. Cryptopygy present, relatively well developed. Claw without inner tooth.

Description. Habitus typical of the genus. Body length (without antennae): 1.5–3.3 mm (holotype: 1.5 mm). Colour of the body bluish-gray. 2+2 eyes relatively small (diameter of ocellus equal to diameter of alveolus Ocp), darkly pigmented ( Fig. 2 ).

Types of dorsal ordinary chaetae. Macrochaetae Ml relatively long, strongly thickened, almost cylindrical, arclike or straight, narrowly sheathed, apically rounded ( Figs 2, 6–7 ); macrochaetae Mc and Mcc thickened, straight and blunt; mesochaetae and microchaetae short, thin, feebly serrated and pointed. Macrochaetae densely covered by minute denticles.

Head. Buccal cone elongated. Labrum pointed, with ventral sclerifications ogival as in Figs 4, 5 . Labrum chaetotaxy 0/2, 2, prelabral chaetae absent. Labium with 11 chaetae: A, C, D, E, F, G, b, c, d, e and f. Labial papillae x not detected ( Fig. 5 ). Maxilla styliform, mandible thin tridentate. Chaetotaxy of antennae as in Tab. 1 b and in Fig. 1 . Apical vesicle poorly developed, trilobed. S–chaetae of ant.IV long and thin, S3 thinner than others ( Fig. 1 ). Group d on ant. III with 4 chaetae. Chaetotaxy of head as in Tab. 1 a and Fig. 2, 5 . Tubercles Cl and Af fused ( Fig. 2 ). Chaeta O absent. Tubercle Dl with 5 chaetae, chaeta Dl6 absent ( Fig. 2 ). Tubercle (L+So) with 8 chaetae, chaetae L2 and L3 absent. Chaeta A distinctly shorter than B.

Chaetotaxy of th. and abd. as in Tab. 1 c and in Figs 2–3, 6–7 . Tubercles Di on th I with 1 chaeta. Tubercles Di on th. II–III with 2 chaetae. Chaetae De 2 on th. II–III and De 3 on th. III connected with tubercle De. Chaetae De 3 on abd. I–III connected with tubercle De ( Fig. 3 ). Tubercle L on abd. III and IV with 4 and 6 chaetae respectively. Furcal vestige without microchaetae. Tubercles Di on abd. V with chaetae Di 2 and Di 3 as Mc ( Fig. 6 ). Chaetae L' and Vl on abd. V present. Cryptopygy present, relatively well developed, Abd. VI hardly visible from dorsal side ( Fig. 6 ). Chaetotaxy of legs as in Tab. 1 c. Tibiotarsi with chaetae B4 and B5 short. Claw without inner tooth.
