Figs 14–21, Tab. 3  
 Material examined. Type material. Holotype, adult female on slide, Russia, Republic of Altai, Central Altai Mts, Terekhtinky Mt. Range, settl. Inya (50 0 28’ N 86 0 36’ E), mosses on cliffs, 14.IX.1988, leg. S. Stebaeva. Paratype, adult female on slide, same locality as holotype, lower part of slope, under barberry, 14.IX.1988, leg. S. Stebaeva. Holotype and other material in the Department of Biodiversity and Evolutionary Taxonomy, Wrocław University; paratype at the Moscow State Pedagogical University.   
 Other material. Adult female, Russia, Novosibirsk Province, 50 km S from Novosibirsk, settl. Chingis (54 0 07’ N 81 0 37’ E), young pine plantation (20 years old), 16.VII.1970, leg. S. Stebaeva. Adult female, Novosibirsk Province, 25 km S from Novosibirsk, (54 0 07’ N 81 0 37’ E), Pinus sibirica plantation, soil 0–5 without litter, 6.X.1993, leg. S. Stebaeva.   
 Diagnosis. Buccal cone elongated. Labral chaetotaxy 4/2, 4. Mandible thin with 3 teeth. Head with 3 chaetae Oc, chaetae A, B, C, D, E and O. Tubercles Dl, L and So with 6, 4 and 6 chaetae respectively. Tubercles Di and De on thoracic tergum I fused.Tubercle Af separate along midline Tubercles De on thoracic terga II and III with 4 and 5 chaetae respectively. Tubercles L on abdominal terga III and IV with 3–4 and 7–8 chaetae respectively. Tubercles Di on thoracic tergum V separate. Cryptopygy absent.   
 Etymology. The new species is dedicated to Dr. S. Stebaeva, Russian collembologist, ecologist and taxonomist, who personally collected the material of the new species and kindly made it available to me.   
 Description. Body length (without antennae): 1.3–2.0 mm (holotype: 1.85 mm). Habitus typical of the Neanurini (Cassagnau 1989). Colour of the body greyish–blue. 3+3 large, dark–pigmented eyes (Fig. 14).   
Types of dorsal ordinary chaetae: macrochaetae Ml thickened, narrowly sheathed, distinctly serrated and apically pointed or rounded (Fig. 15); Mc and Mcc thickened, pointed or rounded at apex; mesochaetae thin and pointed.  
Head. Buccal cone short and rounded at apex. Labrum chaetotaxy 4/2, 4 (Fig. 18), ventral sclerifications as in Fig. 17. Chaetotaxy of labium as in Fig. 17 and in Tab. 3. Maxilla styliform, mandible thin and tridentate. Chaetotaxy of antennae as in Tab. 3. Apical bulb distinct, trilobed. S-chaetae subequal, long and moderately thickened. Chaetotaxy of head as in Figs 14–17 and in Tab. 3. Tubercles Dl, L and So separated (Fig. 16). Tubercles Di and De not fused. Tubercle Di not developed (Fig. 14). Antenno–frontal tubercle separate along midline (Fig. 15). Chaeta O present, chaetae D, E and So2 free (Figs 15, 16). Chaeta A shorter than B.  
Thorax, abdomen, legs. Chaetotaxy of th. and abd. as in Figs 14, 19–21 and in Tab. 3. Tubercles Di and De on th. I fused (Fig. 14). Tubercles De on th. II and III with 4 and 5 chaetae respectively (Fig. 14). Tubercle L on abd. IV with 7–8 chaetae, two chaetae free (Figs 19, 21). S-chaetae shorter than nearby macrochaetae. Tubercles Di on abd. IV–V separated and not fused with other tubercles (Figs 14, 20). Chaetae Vl and L’ on abd. V present (Fig. 19). Cryptopygy absent (Figs 14, 20). Chaetotaxy of legs as in Tab. 3. Claw untoothed.  
 Discussion. The new species is most similar to Kalanura babenkoi sp. nov. (described above), and differences between them are indicated in the key.   
a) Cephalic chaetotaxy.
