Diagnosis. Differs from other species of the genus by the following combination of characters. Promere (pr) round at apex, with a wide lateral lamella (la) (Figs 12A, 12E). Opisthomere (op) with a spike in basal part (Fig. 12B). Lateral outgrowth (lo) of op narrow (Figs 12B, 14F). Striations on metazonae regular and held parallel to one another (Fig. 16F). Ampullae of female vulvae (am1 and am2) elongated and located at different levels; leg-pair 2 (l2) without coxal process (Fig. 18B).
Descriptive notes. Length 28–31 mm, width 1.9–2.8 mm. Number of segments from 46+2+T to 50+1+T. Body grey with a thin, black, dorsal, axial line, venter lighter; legs yellow. Antennae and anal valves brown. Eye patched composed of ca 40 ocelli. Striations on metazonae regular and parallel (Fig. 16F).
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. 1F). Each gnathochilarial stipes with a small group of setae parabasally below mentum (Fig. 2F).
Male leg-pair 1 (Figs 3N–P) with a well-developed suture between coxa (cx) and 1-segmented telopodite remnant (te); cx without lateral outgrowth; te round, with thin setae. Male leg-pair 2 with two coxal processes (Figs 6E–G). Anterolateral process (alp) short. Main process (mp) long, rod-shaped. Penes (p) short, not deeply bifurcate (Fig. 6F).
Promere (pr) round at apex, with a wide lateral lamella (la) (Figs 12A, 12E). The male from near Teberda with an unusual pr carrying a triangular spike in distal part (Figs 12C, 12D). Flagella (fl) thickened and curved in apical part (Figs 12A, 12C).
Opisthomere (op) with a spike in basal part (Fig. 12B). Lateral outgrowth (lo) of op narrow (Figs 14F).
Bursa (bu) of female vulva (vu) with pointed apices, ampullae (am1 and am2) elongated and located at different levels; leg-pair 2 (l2) without coxal process (Fig. 18B).
Remarks. A rare species recorded from lowland Circassia (Stavropol Province) to the mid-montane forest belt in Abkhazia and Georgia (Lohmander 1936; Lang 1959; Kobakhidze 1964, 1965; Lokšina and Golovatch 1979; Talikadze 1984). Chumachenko’s (2011) records of this species from subalpine and alpine meadows in the Caucasian Nature Reserve, Russia are probably erroneous and represent other congener(s).
