Type material. Type material. Male holotype from Quebrada Sutu y Empalado (5°22′42.14″N; 75°53′14.24″W), 1830m, Mistrato , Manpay, Risaralda, Colombia, 3.IV.1992, M. Rocha & G. Andrade leg. (ICN-Ar-10601) .

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

Diagnosis. Males of Patrera sutu n. sp., resemble those of P. philipi Dupérré & Tapia, 2016 and P. hatunkiru Dupérré & Tapia, 2016 , by having a large, strong ventral tegular process ( Fig. 23C ̅E; Dupérré & Tapia, 2016: figs 41, 55), but can be diagnosed by the ventral tegular process apically bifid (entire in P. hatunkiru ), and retrolateral tibial apophysis with the ventral branch apically sharp and longer than dorsal branch (the ventral branch is wider and adjacent to the dorsal one in P. hatunkiru ) ( Fig. 23C ̅E).

Description. Male (Holotype, ICN-Ar-10601). Carapace yellow, darker on the cephalic region ( Fig. 23A ). Chelicerae dark brown. Labium and endites yellow. Legs pale yellow. Sternum yellowish. Abdomen dorsally grayish; ventrally yellow. Spinnerets yellow ( Fig. 23A ). Total length 5.83, carapace length 2.41, width 2.0, high 0.91. Clypeus height 0.11. Eye diameters and interdistances: AME 0.08, ALE 0.19, PME 0.17, PLE 0.19; AME–AME 0.22, AME–ALE 0.3, PME–PME 0.46, PME–PLE 0.4, ALE–PLE 0.39. Chelicerae 1.44 long, four promarginal teeth, six retromarginal teeth, with a large retromarginal and fissidentate Cvp ( Fig. 24B ). Leg measurements: leg I—femur 3.6/ patella 0.98/ tibia 3.93/ metatarsus 3.64/ tarsus 1.88/ total 14.05; II—3.33/ 1.08/ 3.84/ 3.29/ 1.56/ 13.11; III—2.16/ 0.87/ 1.96/ 2.48/ 0.97/ 8.46; IV—3.01/ 1.0/ 2.67/ 3.39/ 1.28/ 11.37. Leg spination: I—tibia v2-2- 0, r1-2-1; II—tibia v2-2-0, metatarsus v2-2-0; III—tibia d1-0-1, v2-2-0, p1-0-1, r0-1-1, metatarsus v2-2-0, p1-2-2, r1-1-2; IV—tibia p1-0-1, r1-0-1, metatarsus v2-2-0, p1-2-2, r1-1-2. Abdomen: length 2.85, epigastric furrow 0.64 from tracheal spiracle, spiracle 1.07 from base of spinnerets. Palp: retrolateral tibial apophysis bifid, long, with the ventral branch longer than dorsal one; cymbium almost as long as tibia; subtegulum longer than wide; tegulum longer than wide, with a strong, large, apically bifid ventral tegular process; median apophysis short, laminar, curved and apically situated; embolus short, apically filiform, with narrow base and proximally inserted on the tegulum ( Fig. 23C ̅E).

Female. Unknown.

Natural History. The holotype was collected manually, in a protected high mountain wet forest ecosystem, to a height of 1830 meters. This species is sympatric with P. perafani n. sp.

Distribution. Only known from Risaralda department ( Fig. 33 ).
