Additional material examined: ECUADOR: Napo: Vinillos (0.6025 °S, 77.8508 °W, 2080 m elev., near Cosanga): 1 male, 29–30.X. 2010, W. & D. Maddison, M. Vega, M. Reyes (WPM# 10 -036). Reserva Ecológica Antisana , Sendero Jumandy (0.6245 °S, 77.8402 °W, 2260 m elev.): 2 males, 29.X. 2010, W. & D. Maddison & M. Reyes (UBC-SEM).

Etymology: This attractive species is named in honour of G.B. Edwards, to recognize his important contributions to our understanding of salticids of the Americas.

Diagnosis: Males of U. edwardsi are similar to U. occidentale sp. nov. in having an acute projection on the ventral lobe of the RTA, which is longer in U. edwardsi ( Figs 28 View FIGURES 27 – 31 , 33 View FIGURES 32 – 35 ). Females differ from those of U. antisana in having copulation openings parallel to the body axis ( Fig. 30 View FIGURES 27 – 31 ). In the northern localities east of Quito, U. edwardsi is easily distinguished from U. antisana by having yellow rather than dark brown legs ( Figs 1–5 View FIGURES 1 – 5 ).

Description: Male (holotype): Total length: 2.90. Carapace dark brown, 1.35 long, 0.92 wide, 0.70 high. Ocular quadrangle 0.65 long. Anterior eye row 0.90 wide and posterior 0.85 wide. Sternum, labium, endite and chelicera dark brown. Palp dark brown, tibia with a wide RTA forming a hook dorsally and bearing an acute projection retrolaterally, and an acute RvTA; embolus fixed to the tegulum and curling around it, with a median blunt projection lying in a pit of the prolateral side of tegulum ( Figs 27–29 View FIGURES 27 – 31 ). Legs yellow, except for entire femora I–IV and proventral tibiae and metatarsi I–II, dark brown. Length of femur I: 1.00, II: 0.60, III: 0.55, IV: 0.70; patella + tibia I: 1.30, II: 0.75, III: 0.57, IV: 0.75; metatarsus + tarsus I: 0.90, II: 0.60, III: 0.57, IV: 0.67. Leg spination: femur I d 0-1 -0, II–III d 0-1 - 1, IV d 1 - 1 - 1; patella I–IV 0; tibia I v 1 r- 2 -0, II v 0-1 r-0, III–IV r 0-1 -0; metatarsus I v 1 r- 2, II v 1 r- 1 p, III–IV p 0-1, r 0-1, v 0- 1 p. Abdomen light brown with chevrons on posterior half. Spinnerets dark brown.

Female (paratype): Total length: 2.60. Carapace dark brown, 1.30 long, 0.92 wide, 0.62 high. Ocular quadrangle 0.65 long. Anterior eye row 0.90 wide and posterior 0.90 wide. Sternum, labium, endite and chelicera dark brown. Palp and legs yellow, except for a dark brown mark on distal fourth of retrolateral femur IV. Length of femur I: 0.65, II: 0.55, III: 0.50, IV: 0.70; patella + tibia I: 0.75, II: 0.62, III: 0.55, IV: 0.75; metatarsus + tarsus I: 0.55, II: 0.47, III: 0.52, IV: 0.60. Leg spination: femur I–II 0, III d 0-1 - 1 or 0- 0-1, IV d 0-1 -0; patella I–IV 0; tibia I v 1 r- 2 -0, II v 0-1 r-0, III–IV 0; metatarsus I–II v 2 - 2, III p 0-1, r0, v0, IV p 0-1, r 0-1, v 1 p-0 or v 0- 1 p. Abdomen dark brown. Epigyne with small U-shaped copulation openings forming an atrium; copulation ducts begin as wide chambers and extend backwards, fold at the center, extend anteriorly and connect to small spermathecae, from which fertilization ducts emerge ( Figs 30–31 View FIGURES 27 – 31 ).
