Diagnosis.

This species resembles Q. turbinata (Figs 5 View Figure 5 , 6 View Figure 6 ) in having a bifurcated retrolateral tibial apophysis (RTA), a crescent-shaped and grooved conductor (C), a long and slender embolus (E) originated at approximately 6 - o’clock position, spine-like embolic process (EBP) pointing anteriorly and a slit-like copulatory openings (CO) of epigyne, but differs by smaller body size (16.23–18.14) (Fig. 6 B, D View Figure 6 , vs 27.45–34.33); relatively thick anterior branch of retrolateral tibial apophysis (Fig. 2 E – H View Figure 2 , vs with lamellar and pleated in Q. turbinata , Fig. 5 E – H View Figure 5 ); relatively pointed tip of conductor in ventral view (Fig. 2 B View Figure 2 , vs blunt, Fig. 5 B View Figure 5 ). Posterior part of epigynal median plate wider than half of anterior part (Fig. 3 A, B View Figure 3 , vs narrower than half of the anterior part, Fig. 6 A, B View Figure 6 ).

Carapace yellow-brown, margin dark brown, with red brown radial furrow. Dorsum of abdomen dark brown, cardiac pattern rhomboid yellow-brown, with two pairs of brown muscular mark. Eye sizes and interdistances: AME 0.43, ALE 0.34, PME 0.41, PLE 0.43; AME – AME 0.26, AME – ALE 0.15, PME – PME 0.22, PME – PLE 0.53. Clypeus height 0.55. Spination of left leg I: Fe 3 d 5 p 5 r; Pa 1 d 1 p 1 r; Ti 2 d 2 p 2 r 4-4 v; Mt 3 d 3 p 3 r 3-0 v. Leg measurements: I 42.75 (10.80, 15.56, 11.98, 4.41); II 45.58 (11.65, 16.83, 12.75, 4.35); III 36.49 (9.88, 12.94, 10.05, 3.62); IV 40.67 (10.15, 14.00, 12.20, 4.32).

Palp (Fig. 2 View Figure 2 ). Tibia ca 2 times longer than wide in retrolateral view, ca 0.4 of femur length, as long as patella, proximal part wider than distal RTA length in ventral view, with two strong prolateral spines; tibial apophysis bifurcated, anterior branch thick, with lamellar margin, posterior branch hook-like, curved, extending dorso-anteriorly, with pointed tip. Cymbium droplet-shaped, 2 times longer than wide, ca 1.7 times of tibia length and width; cymbial furrow (CF), ca 0.6 times of cymbium length; tip 0.4 times of cymbial length; dorso-posterior part extended posteriorly (Fig. 2 F View Figure 2 ). Bulb slightly elliptical, as long as wide; proximal terminal part of tegulum (T) funnel-shaped and curved; subtegulum (St) triangular in retrolateral view; median apophysis (MA) located centrally, hook-like. Conductor crescent-shaped in ventral view, with groove in retrolateral view (holding fulcrum (Ful) and embolus), with pointed tip. Embolus complex: with fulcrum (Ful) and basal process (EBP); fulcrum long, curved clockwise as long as embolus; basal process spine-like. Embolus proper originating at approximately 6 - o’clock position, long, running clockwise surrounded tegulum, distal part resting in long groove of fulcrum and terminating at ca 3 - o’clock position.

Female (Figs 1 B View Figure 1 , 4 B View Figure 4 ). Total length 18.14. Carapace 6.72 long, 6.33 wide; abdomen 11.62 long, 7.71 wide. Carapace yellow-brown, margin gray-brown, with radiating dark-brown radial furrow. Dorsum of abdomen dark brown, with sagittal cardiac pattern and four symmetrical muscular impressions on either side. Eye sizes and interdistances: AME 0.35, ALE 0.31, PME 0.35, PLE 0.40; AME – AME 0.28, AME – ALE 0.16, PME – PME 0.24, PME – PLE 0.47. Clypeus height 0.44. Chelicerae brown, with three promarginal and three retromarginal teeth. Spination of left leg I: Fe 3 d 5 p 5 r; Pa 1 d 1 p 1 r; Ti 2 d 2 p 2 r 4-4 v; Mt 3 d 3 p 3 r 3-0 v. Leg measurements: I 32.95 (8.72, 12.14, 8.87, 3.22); II 35.91 (9.62, 13.28, 9.73, 3.28); III 28.55 (7.93, 9.69, 8.10, 2.83); IV 32.08 (8.64, 11.01, 9.26, 3.17).

Epigyne (Fig. 3 View Figure 3 ). Epigynal plate ca 1.3 times wider than long (as long as wide in holotype). Anterior part of median plate (MP) 1.5 times wider than posterior part (equal in holotype). Copulatory openings (CO) slit-like, located mid ventrally on between lateral walls (LW) and median plate. Copulatory ducts (CD) wrapped 3 times around base of spermatheca (BS); spermatheca head (SH) almost spherical (elongated oval in holotype). Fertilization ducts (FD) crescent-shaped.
