O. Gvozdeva  ; 1 male ( ZMUMAbout ZMUM), same locality, Fagus  forest, 650 m a.s.l., 14.V.1981, leg  . V. Matveeva; 1 male, 1 juvenile ( ZMUMAbout ZMUM), S slope of Tseissky Mt.

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 View Figure ). Gonopodal promere (pr) wide, with a lateral lamella (la) ( Fig. 12H View Figure ). Flagella (fl) thick, each with a lamina on top ( Fig. 12G View Figure ). Mesomere (ms) and apex of opisthomere (op) rounded ( Figs 12G, 12I View Figure , 14G View Figure ). Lateral outgrowth (lo) of op higher than ms ( Fig. 18C View Figure ). Striations on metazonae thin, shallow, irregular, not parallel to one another ( Fig. 16G View Figure ). 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 View Figure ).

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

Male leg-pair 1 with a weakly expressed suture between coxa (cx) and a 1-segmented telopodite remnant (te) ( Figs 3Q–R View Figure ); 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 View Figure ). 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 View Figure ).

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

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

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

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 View Figure ).

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).
