Diagnosis. Differs from other species of the genus by the following combination of characters. Main process (mp) of male leg-pair 2 curved laterally (Figs 7A–B). Gonopodal promere (pr) wide, with a lateral lamella (la) (Fig. 12H). Flagella (fl) thick, each with a lamina on top (Fig. 12G). Mesomere (ms) and apex of opisthomere (op) rounded (Figs 12G, 12I, 14G). Lateral outgrowth (lo) of op higher than ms (Fig. 18C). Striations on metazonae thin, shallow, irregular, not parallel to one another (Fig. 16G). Ampullae of female vulva (vu) located at different levels, ampulla 1 (am1) narrow and elongated, ampulla 2 (am2) rounded. Coxa of female leg-pair 2 (l2) with rounded processes (Fig. 18C).

Descriptive notes. Length 18–28 mm, width 1.1–2.2 mm. Number of segments from 38+2+T to 50+1+T. Body light grey with a thin, black, dorsal, axial line, venter lighter; legs yellow. Antennae and anal valves greyish yellow. Each eye patch composed of ca 40 ocelli. Striations on metazonae thin, shallow, irregular, usually not parallel to one another (Fig. 16G).

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. Each stipes of gnathochilarium with a group of setae placed on a small tubercle below mentum (Fig. 2G).

Male leg-pair 1 with a weakly expressed suture between coxa (cx) and a 1-segmented telopodite remnant (te) (Figs 3Q–R); cx with a lateral acuminate outgrowth; te elongated, with a group of thick setae. Male leg-pair 2 with two coxal processes (Figs 7A–B). Anterolateral process (alp) short, acuminate, with a medial spike-like outgrowth. Main process (mp) long, curved laterally. Penes short, relatively narrow, not deeply bifurcate (Fig. 7A).

Promere (pr) wide, with a lateral lamella (Fig. 12H). Flagella (fl) thick, with a lamina on top (Figs 12G, 12I).

Mesomere (ms) rounded, opisthomere (op) bifurcate on top (Fig 12G, 12I). Lateral outgrowth (lo) of op higher than ms (Fig. 14G).

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

Female vulva (vu) with rounded apices on bursa (bu); ampulla 1 (am1) narrow and elongated, ampulla 2 (am2) rounded and located above am1. Leg-pair 2 (l2) of female with wide, rounded, coxal processes (Fig. 18C).

Remarks. One of the high-montane species of the genus in the Caucasus, occurring in the upper forest belt, as well as subalpine and alpine meadows. Recorded from North Ossetia and the Krasnodar Province (Lohmander 1936; Lang 1959; Lokšina and Golovatch 1979).
