Diagnosis. Differs from the other two species of the genus by the shape of the anterior gonopods which resemble butterfly wings.

Etymology. To emphasize, in anterior view, the butterfly wing-shaped anterior gonopods.

Description. Body with 31 segments (including telson) in adults.

MEASUREMENTS. Males 8.5–9.5 mm long, vertical diameter of the largest pleurotergite 0.7–0.75 mm. Females 9–11 mm long, vertical diameter of the largest pleurotergite 0.8–0.85 mm.

COLORATION ( Fig. 147 View FIGURE 147 ). Dorsal and lateral sides of prozonites greyish, dorsolateral and ventrolateral sides with yellowish spots. Metazonites brownish with yellowish spots on lateral keels.

HEAD. Flattened in males. Labrum with three medial teeth and 6+6 labral and 2+2 supralabral setae. Promentum triangular, without setae. Lingual plates with 5+5 setae, on each plate arranged in one irregular row. Stipites with 20+20 setae. Antennae 1.4 mm long in male from Girdyman-Chay Valley. Length of antennomeres (in mm): I (0.08), II (0.15), III (0.35), IV (0.16), V (0.35), VI (0.15), VII (0.13) and VIII (0.03). Length/breadth ratios of antennomeres I–VII: I (1), II (1.7), III (5), IV (2.3), V (3.9), VI (1.5) and VII (1.8). Antennomeres II, IV, V, VI and VII with one, three, one, four and one sensillum, respectively. Number of ocelli 15–20, arranged in 5–6 rows in males; 14–20 in 5–6 rows in females.

COLLUM. Narrower than head, with six macrochaetae. Anterior edge semi-circular, posterior margin gently concave.

BODY SEGMENTS ( Figs 147 View FIGURE 147 , 148 View FIGURE 148 ). Lateral keels like lateral swellings. Macrochaetae relatively long and trichoid. CIX (pleurotergite 15) ~ 0.7; MIX (pleurotergite 15) ~ 1.7; PIX (pleurotergite 15) ~ 0.75; MA (pleurotergite 15) ~ 105˚.

TELSON. Epiproct with a pair of spinnerets and 3+3 setae (1+1 paramedian, 2+2 marginal). Hypoproct with 1+1 apical setae. Paraprocts with 3+3 marginal setae.

WALKING LEGS. In both sexes, leg-pairs 1 and 2 with tarsal combs; prefemora with several long and robust setae; femora and postfemora with a group of several long and robust setae.

MALE SEXUAL CHARACTERS ( Fig. 149 View FIGURE 149 ). Leg-pairs 3–7 enlarged. Leg-pairs 3 and 4 each with a basal exterior protrusion on prefemur. Leg-pair 5 with an acuminate, basal, oral protrusion on prefemur. Leg-pair 6 with a small, basal, exterior protrusion. Leg-pair 7 with a caudally directed, subtriangular, lamellar process, mesally clothed with abundant long setae. Leg-pair 10 with coxal glands and with a posteriorly curved coxal horn, apex of horn being curved mesally. Leg-pair 11 with coxal glands, without other peculiarities.

ANTERIOR GONOPODS ( Figs 150 View FIGURE 150 A–C, 151A–E). Sternal plate (sp) with an anterior, medial, sternal lamella (sl) protecting a nippled sternal sac (ss). Coxal processes divided in distal halves, basal halves being fused. Anteriorly, coxal processes partly divided transversely (td) into a medial part (mp) and lateral parts (lp), giving the impression of butterfly wings. Medially, mesal edges clothed with posteriorly curved denticles (pd). Coxal processes anteriorly with a pair of long and slender processes (pf), in situ sunk apically in a transverse rift. Posteriorly, gonopods with a lamella (dl) denticulate starting from apex; hairy levers (hl), a row of setae (rs) and a spoon-shaped lamella (ssl) also present.

POSTERIOR GONOPODS ( Figs 150 View FIGURE 150 D, 151F–H). Very simple. Coxites (c) divided. Telopodites (t) present on posterolateral side. Anterior side with coxal vesicles (cv). Apices of coxal processes (cp) hairy. Distribution. Azerbaijan, Georgia ( Fig. 169 View FIGURE 169 , orange triangle).
