Diagnosis. Differs from other species of the genus by the following combination of characters. Coxa (cx) of male leg-pair 1 with a small lateral outgrowth ( Figs 3E, 3F View FIGURE 3 ). Gonopodal promere (pr) relatively wide, with a long, thin, basal lamella (la) ( Figs 9A, 9C View FIGURE 9 ). Mesomere (ms) rounded ( Figs 9B View FIGURE 9 , 14C View FIGURE 14 ). Lateral outgrowth (lo) of op large, pointed distally ( Fig. 14C View FIGURE 14 ). Striations on metazonae irregular, not parallel to one another ( Fig. 16C View FIGURE 16 ). Ampulla 1 (am1) of female vulva (vu) not expanded, ampulla 2 (am2) rounded, each located at different levels; female coxa 2 (l2) with a small, rounded, apicomesal outgrowth ( Fig. 17C View FIGURE 17 ).

Descriptive notes. Length of adults 18–35 mm, width 1.2–1.9 mm. Number of segments in adults from 40+1+T to 47+1+T. Body dark brown, marbled greyish with a thin, black, dorsal, axial line, venter lighter; legs yellow. Antennae and anal valves greyish. Eye patches composed of 45–50 ocelli. Striae on metazonae irregular, often not parallel to one another ( Fig. 16C View FIGURE 16 ).

All other characters as in J. alexandrae , except as follows. Antennae in situ reaching back to body segment 3. Antennomeres 5 and 6 each with a corolla of bacilliform sensilla ( Fig. 1C View FIGURE 1 ). Each stipes of gnathochilarium with a group of 10–20 setae placed parabasally on a small tubercle below mentum ( Fig. 2C View FIGURE 2 ).

Male leg-pair 1 ( Figs 3E–F View FIGURE 3 ) with a well-developed suture between coxa (cx) and a 1-segmented telopodite remnant (te); cx with a small lateral outgrowth, te round, with a group of thick setae. Male leg-pair 2 with two coxal processes ( Fig. 4E–F View FIGURE 4 ). Anterolateral process (alp) short and acuminate, main process (mp) long, straight and rod-shaped.

Promere (pr) relatively wide, with a lateral lamella (la) ( Fig. 9C View FIGURE 9 ); flagella (fl) thickened in apical third ( Fig. 9A–B View FIGURE 9 ). Mesomere (ms) rounded ( Fig. 9B View FIGURE 9 ). Lateral outgrowth (lo) of opisthomere (op) large, pointed ( Fig. 14C View FIGURE 14 ).

Ventral edge of male segment 7 with small curved lamellae bordering the gonopodal aperture ( Fig. 15C View FIGURE 15 ).

Female vulva (vu) narrow, bursa (bu) with a pointed apical outgrowth. Ampulla 1 (am1) not expanded, ampulla 2 (am2) rounded, each located at different levels; coxa 2 (l2) with a small, rounded, apicomesal outgrowth ( Fig. 17C View FIGURE 17 , see also Golovatch 1981).

Remark. This species is a localized endemic of North Ossetia ( Golovatch 1981), inhabiting the upper forest to alpine belts at altitudes 1800–2900 m a.s.l.
