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 View Figure ). Opisthomere (op) with a spike in basal part ( Fig. 12B View Figure ). Lateral outgrowth (lo) of op narrow ( Figs 12B View Figure , 14F View Figure ). Striations on metazonae regular and held parallel to one another ( Fig. 16F View Figure ). Ampullae of female vulvae (am1 and am2) elongated and located at different levels; leg-pair 2 (l2) without coxal process ( Fig. 18B View Figure ).

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 View Figure ).

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 View Figure ). Each gnathochilarial stipes with a small group of setae parabasally below mentum ( Fig. 2F View Figure ).

Male leg-pair 1 ( Figs 3N–P View Figure ) 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 View Figure ). Anterolateral process (alp) short. Main process (mp) long, rod-shaped. Penes (p) short, not deeply bifurcate ( Fig. 6F View Figure ).

Promere (pr) round at apex, with a wide lateral lamella (la) ( Figs 12A, 12E View Figure ). The male from near Teberda with an unusual pr carrying a triangular spike in distal part ( Figs 12C, 12D View Figure ). Flagella (fl) thickened and curved in apical part ( Figs 12A, 12C View Figure ).

Opisthomere (op) with a spike in basal part ( Fig. 12B View Figure ). Lateral outgrowth (lo) of op narrow ( Figs 14F View Figure ).

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 View Figure ).

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).
