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 , 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.

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 ). 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 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. FIGURE 148.
