Figures 5A–D ; 31

Type material. Male holotype from Reserva Natural Rio Ñambí (1°14′45.22″N, 78°6′54.71″W), 1450m, Barbacoas, Vereda Altaquer Nariño, Colombia, 14.IX.2004, D. Martínez & D. Luna leg. (ICN-Ar-10604) .

Etymology. The specific epithet is a noun in apposition to the type locality.

Diagnosis. Males of Patrera barbacoas n. sp. resemble those of P. platnicki n. sp. by having the abdomen with several dark patches and subquadrate retrolateral tibial apophysis ( Fig. 10B ̅D), but can be distinguished by the retrolateral tibial apophysis narrower (larger and wider in P. platnicki ) and apically subrounded, and embolus inserted on the base of the tegulum (inserted near the middle of tegulum in P. platnicki ) ( Fig. 5B ̅D).

Description. Male (Holotype, ICN-Ar-10604). Carapace brownish, darker on the cephalic region ( Fig. 5A ). Chelicerae dark brown. Labium and endites brown. Sternum yellowish. Legs yellow, darkest from tibiae to tarsi. Abdomen pale yellow with black spots and black setae; ventrally pale yellow. Spinnerets yellow ( Fig. 5A ). Total length 8.12, carapace length 3.76, width 4.47, high 1.81. Clypeus height 0.21. Eye diameters and interdistances: AME 0.15, ALE 0.27, PME 0.24, PLE 0.27; AME–AME 0.34, AME–ALE 0.50, PME–PME 0.67, PME–PLE 0.67, ALE–PLE 0.57. Chelicerae 1.8 long, four promarginal teeth, five retromarginal denticles. Leg measurements: leg I—femur 4.35/ patella 1.68/ tibia 4.76/ metatarsus 3.41/ tarsus 2.01/ total 16.21; II—4.32/ 1.65/ 4.78/ 2.76/ 1.9/ 15.41; III—3.37/ 1.52/ 2.99/ 3.24/ 1.12/ 12.24; IV—4.08/ 1.56/ 3.68/ 4.17/ 1.54/ 15.03. Leg spination: I—metatar-sus v1-2-0, p0-1-0, r0-1-0; II—metatarsus v2-2-0, p1-1-0, r1-1-0; III— tibia d1-0-0, p0-1-1, r0-1-1, metatarsus p1- 2-2, r1-1-2; IV—tibia d1-0-0, p1-0-1, r1-1-1, metatarsus p1-2-2, r1-1-2. Abdomen: length 4.34, epigastric furrow 1.19 from tracheal spiracle, spiracle 1.77 from base of spinnerets. Palp: retrolateral tibial apophysis large with apical denticles; cymbium longer than tibia; subtegulum longer than wide with apically conical distal projection; tegulum longer than wide; median apophysis very short and basally situated; embolus long with narrow base, basally inserted on the tegulum ( Fig. 5B ̅D).
