Etymology. The specific epithet is a patronym in honor to Richard Dawkins, for his valuable contributions to the scientific divulgation and to the understanding of evolution.

Diagnosis. Males of Patrera dawkinsi n. sp. resemble those of P. witsu Dupérré & Tapia, 2016 by the shape of the ventral tegular process and by the retrolateral tibial apophysis with enlarged ventral branch (see Dupérré & Tapia, 2016:36, fig. 49), but can be diagnosed by the very elongated, larger ventral tegular process (shorter, smaller in P. witsu ), retrolateral tibial apophysis with long ventral branch, apically sharp, and apically sub-rounded dorsal branch (the ventral branch is narrower and square in the apex in P. witsu ) ( Fig. 25 View FIGURE 25 B–D).

Description. Male (Holotype, ICN-Ar-10603). Carapace brownish, darker on the cephalic region ( Fig. 25A View FIGURE 25 ). Chelicerae dark brown. Labium and endites brown. Sternum yellowish. Legs yellow, becoming darkest from tibiae to tarsi. Abdomen dorsally pale yellow with gray spots; ventrally pale yellow. Spinnerets yellow ( Fig. 25A View FIGURE 25 ). Total length 3.63, carapace length 1.68, width 1.27, high 0.57. Clypeus height 0.06. Eye diameters and interdistances: AME 0.05, ALE 0.11, PME 0.09, PLE 0.09; AME–AME 0.13, AME–ALE 0.21, PME–PME 0.32, PME–PLE 0.29, ALE–PLE 0.27. Chelicerae 0.82 long, four promarginal teeth, six retromarginal denticles, one of the retromarginal denticles biggest. Leg measurements: leg I—femur 2.41/ patella 0.77/ tibia 2.88/ metatarsus 2.58/ tarsus 1.22/ total 9.86; II—2.05/ 0.68/ 2.21/ 1.83/ 0.84/ 7.61; III—1.3/ 0.58/ 1.2/ 1.45/ 0.57/ 5.1; IV—1.73/ 0.57/ 1.66/ 2.08/ 0.71/ 6.75. Leg spination: I—tibia v2-2-0, metatarsus v2-0-1; II—tibia v2-2-0, metatarsus v2-0-1; III—tibia d1-0-0, v1- 1-1, p0-1-1 r0-1-1, metatarsus v2-2-0, p1-2-2, r1-1-2 IV—tibia d1-0-0, v1-2-2, p0-1-1, r0-1-1, metatarsus v2-1-2, p1-2-2, r1-1-2 Abdomen: length 1.82, epigastric furrow 0.64 from tracheal spiracle, spiracle 0.69 from base of spinnerets. Palp: retrolateral tibial apophysis bifid, large, with the ventral branch wider and longer than dorsal branch, which is thin; cymbium almost as long as tibia; subtegulum longer than wide; tegulum longer than wide, with a strongly sclerotized, large, laminar ventral tegular process; median apophysis short, curved, apically situated; embolus short, apically filiform, with narrow base and proximally inserted on the tegulum ( Fig. 25 View FIGURE 25 B–D).

Female. Unknown.

Distribution. Only known from Nariño department ( Fig. 33 View FIGURE 33 ).
