Diagnosis. Differs from other species of the genus by the following combination of characters. Main process (mp) of male leg-pair 2 long, with two outgrowths. The distofrontal one more or less large and thick. The caudal outgrowth small and short ( Figs 4G–I View FIGURE 4 ). Gonopodal promere (pr) very narrow, broadly rounded at apex, with a wide lamella (la) ( Figs 10B, 10D, 10F View FIGURE 10 ). End of pr more or less clearly narrowed. Flagella (fl) well-developed, each with a spike-like outgrowth in middle part ( Fig. 10B View FIGURE 10 ). Opisthomere (op) with an elongated lateral outgrowth (lo) sharpened at apex ( Fig. 14D View FIGURE 14 ). Striations on metazonae superficial and irregular ( Fig. 16D View FIGURE 16 ). Bursa (bu) of female vulva (vu) with well-developed apical outgrowths; ampullae (am1 and am2) different in size; female leg-pair 2 (l2) with a large coxal process ( Fig. 17D View FIGURE 17 ).

Descriptive notes. Length of adults 28–38 mm, width 1.6–2.4 mm. Number of segments in adults from 52+1+T to 57+2+T. Body grey-brown with a thin, black, dorsal, axial line, lighter on ventral side; legs light brown, antennae and anal valves grey. Eye patches composed of 40–45 black ocelli. Striae on metazonae shallow and irregular ( Fig. 16D View FIGURE 16 ).

All other characters as in J. alexandrae , except as follows. Antennae in situ reaching back to body segment 5. Antennomeres 5 and 6 each with a sparse corolla of bacilliform sensilla ( Fig. 1D View FIGURE 1 ). Each stipes of gnathochilarium with a rather compact group of ca 17 setae placed parabasally below mentum ( Figs 2D View FIGURE 2 ).

Male leg-pair 1 ( Figs 3G–I View FIGURE 3 ) with a well-developed suture between coxa (cx) and a roundish 1-segmented telopodite remnant (te); cx with a distolateral outgrowth, rounded at apex; te with a group of thick setae. Male legpair 2 with three coxal processes ( Figs 4G–I View FIGURE 4 ): anterolateral process (alp) short; main process (mp) long and with two outgrowths, including a more or less thick and large distofrontal branch and a small and short caudal outgrowth; posterior process (pp) short and with two basal setae. Penes (p) short, not deeply bifurcate, with two small claws crossing at apex ( Fig. 4G View FIGURE 4 ).

Gonopodal promere (pr) very narrow, widely rounded at apex, with a wide lateral lamella (la) ( Figs 10B, 10D, 10F View FIGURE 10 ). End of pr more or less narrowed. Flagella (fl) long and thick, with an anchor-shaped outgrowth near midpoint ( Fig. 10B View FIGURE 10 ). Apex of a particularly short mesomere (ms) narrow ( Figs 10C, 10G View FIGURE 10 , 14D View FIGURE 14 ). Opisthomere (op) with an elongated, sharpened ( Fig. 14D View FIGURE 14 ) or rounded ( Fig 10C View FIGURE 10 ), lateral outgrowth (lo) at apex.

Ventral edges of male segment 7 on each side with a small curved lamella bordering a small, inconspicuous gonopodal aperture ( Fig. 15D View FIGURE 15 ).

Bursa (bu) of female vulva (vu) with well-developed apical outgrowths. Ampullae (am1 and am2) rounded, slightly different in size; leg-pair 2 (l2) with a large coxal process ( Fig. 17D View FIGURE 17 ).

Remarks. In the Caucasus, this is the second most common species following J. colchicus . It has been recorded from the Krasnodar Province, the Adygea, Karachaevo-Cherkessia and North Ossetia republics, and Abkhazia ( Verhoeff 1921; Lohmander 1936; Lang 1959; Kobakhidze 1965; Lokšina and Golovatch 1979; Talikadze 1984), being widely distributed from lowlands to elevations about 2000 m a.s.l.

Intraspecific variation: The species shows only minor variations in the structure of male legs-pairs 1 and 2, and of the gonopods.
