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, S 3 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 Dl 6 absent (Fig. 2).

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.
