Figs 58, 60–64, 66–69 View FIGURES 58 – 69 , Tables 11–12 View TABLE 11 View TABLE 12

Etymology. The name of the species is derived from its terra typica Kedrovaya Pad, a biologically major nature reserve in the region which hosts some of the most emblematic mammals of eastern Palearctic.

Diagnosis. Body white. 2+2 eyes on head. Tubercles and reticulations not developed. Head with chaetae O, A, chaetae E sometimes absent. Head with three ocular chaetae. Thorax I with 2 chaetae De. Thorax II–III with 3 chaetae Di. Thorax II–III with 3 and 4 ordinary chaetae De respectively. Abdomen V with 2+2 chaetae Di. Abdomen V slightly longer than VI. Abdomen without clavate chaetae. Furca rudimentary without microchaetae. Male ventral organ absent. Tibiotarsi without chaetae M.

Description. Habitus typical for Paranura Axelson, 1902 genus. Buccal cone elongate. Body length (without antennae) 0.68–1.05 mm (holotype: 0.72 mm). Colour of body when alive and in alcohol white. Tubercles and reticulations not developed. Ordinary dorsal chaetae ( Figs 60, 68 View FIGURES 58 – 69 ) differentiated into short, thin, acuminate microchaetae, medium size, smooth, acuminate mesochaetae and long, nearly smooth (with small denticles visible under large magnification, Fig. 68 View FIGURES 58 – 69 ), relatively thick, arc-like at apex macrochaetae Ml and Mc. No plurichaetosis on body.

Head. Antennae slightly shorter than head ( Fig. 60 View FIGURES 58 – 69 ). S-chaetae of ant. IV relatively long and thin, S1 and S2 slightly thinner than others ( Fig. 64 View FIGURES 58 – 69 ). Apical bulb trilobed ( Figs 62, 63 View FIGURES 58 – 69 ). Chaetotaxy of antennae as in Fig. 64 View FIGURES 58 – 69 and Tab. 11 View TABLE 11 . Buccal cone relatively long and rounded at apex. Maxilla needle-like, mandible simple with three teeth. Chaetotaxy of labium as in Fig. 58 View FIGURES 58 – 69 , labial papillae x absent. Labrum chaetotaxy 4/2,4,4 ( Fig. 61 View FIGURES 58 – 69 ). Group Vi with 6+6 chaetae ( Fig. 58 View FIGURES 58 – 69 ). Groups Vea, Vem and Vep with 4, 3 and 4 chaetae respectively. Dorsal chaetotaxy of head as in Tab. 11 View TABLE 11 . and Fig. 60 View FIGURES 58 – 69 . Dorsal chaetotaxy of central area on head complete, with 3 chaetae Oc and chaetae A, B, C, D, E (absent on one side in one specimen), F, G, O. Line of chaetae Di2–De2 crosses line Di1–De1 on head (crosstype, Deharveng 1983). 2+2 relatively small black eyes with diameter two times as large as the diameter of chaeta Ocm socket ( Fig. 60 View FIGURES 58 – 69 ).

Thorax, abdomen, legs. Dorsal chaetotaxy as in Fig. 60 View FIGURES 58 – 69 and in Tab. 12 View TABLE 12 . Ventral chaetotaxy as in Tab. 12 View TABLE 12 and Fig. 67 View FIGURES 58 – 69 . S-chaetae long, slightly longer or equal to nearby macrochaetae ( Figs 60, 69 View FIGURES 58 – 69 ). S-chaetae formula of body: 022/11111, s-microchaeta on Dl of th. II present. Furcal remnant with 3–4 mesochaetae and without microchaetae ( Fig. 67 View FIGURES 58 – 69 ). Male without ventral modified chaetae (“male ventral organ”). Claw without internal tooth. Chaeta M absent on tibiotarsus, chaetae B4 and B5 short. Chaetotaxy of legs as in Tab. 12 View TABLE 12 and Fig. 66 View FIGURES 58 – 69 .

Types. Holotype male subadult and 2 paratypes (1 female, 1 juvenile) on slides, Russia: Primorye: Khasansky: Reserve Kedrovaya Pad: core area, forest with Pinus koreensis & Abies sp., litter and moss on soil, Berlese, 29.IX.2004, leg. L. Deharveng & A. Bedos, X=131.533219°, Y=43.110513°, altitude about 70 m (RU-134). Holotype deposited in MNHN, paratypes in DIBEC and MSPU.

Remarks. Among described Asiatic forms Paranura kedrovayensis sp. nov. is similar to P. mjohjangensis Deharveng & Weiner, 1984 (from North Korea) but they clearly differ in the number of eyes (in P. kedrovayensis sp. nov. 2+2, in mjohjangensis 3+3), number of labial lateral chaetae (in P. kedrovayensis sp. nov. 3, in mjohjangensis 4 Fig. 59 View FIGURES 58 – 69 ) and number of trochanteral chaetae (in P. kedrovayensis sp. nov. 5, in mjohjangensis 6 Fig. 65 View FIGURES 58 – 69 ). See also in remarks of P. microchaetosa sp. nov.

Biology. The new species is resident in montane coniferous forests. Bisexual species.

a) Cephalic chaetotaxy––dorsal side.

b) Chaetotaxy of antennae.
