Type material. Female holotype from Sabana Rubia, (10°22′8.6″N; 72°52′33.6″W), 3200–3400m, Serranía del Perijá , Cesar, Colombia, 16-20-XII.2016, E. Villarreal, L. Martínez & C. Pinzón leg. (ICN-Ar-10632) GoogleMaps .

Etymology. The specific epithet is referring to an Andean formation and type locality called “Serranía del Perijá”. It is the most northern branch of the Andean mountains.

Diagnosis. Females of Patrera perijaensis n. sp., resemble those of P. florezi n. sp. and P. wiwa n. sp., by having the similar shape of hood and n-shaped copulatory ducts ( Figs 16 View FIGURE 16 F–G, 21F–G), but can be diagnosed by having very large and subrounded hood (thinner in P. florezi ), wide copulatory ducts, and larger spermathecae (thinner and smaller respectively in P. florezi ) ( Fig. 17 View FIGURE 17 B–C).

Description. Female (Holotype, ICN-Ar-10632). Carapace yellow, darker in the ocular region ( Fig. 17A View FIGURE 17 ). Chelicerae yellow. Labium pale brown and endites yellow. Sternum yellow. Legs yellow, with some gray patches on all segments. Abdomen yellow with some dark gray patches distribuites on all dorsal and ventral surfaces ( Fig. 17A View FIGURE 17 ). Spinnerets yellow. Total length 6.66, carapace length 3.12, width 2.47, high 1.17. Clypeus height 0.07. Eye diameters and interdistances: AME 0.10, ALE 0.17, PME 0.16, PLE 0.16; AME–AME 0.27, AME–ALE 0.3, PME–PME 0.46, PME–PLE 0.38, ALE–PLE 0.43. Chelicerae 1.2 long; six promarginal teeth; four retromarginal teeth. Leg measurements: leg I—femur 2.89/ patella 1.39/ tibia 3.19/ metatarsus 2.37/ tarsus 1.48/ total 11.32; II—2.83/ 1.30/ 2.85/ 2.23/ 1.35/ 10.56; III—2.23/ 1.04/ 1.9/ 1.88/ 0.96/ 8.01; IV—3.17/ 1.18/ 2.95/ 3.1/ 1.14/ 11.54. Leg spination: I—metatarsus v2-0-0, p1-1-0, r1-1-0; II—metatarsus v2-0-0, p1-1-0, r1-1-0; III—tibia d1-0-0 p1-1-1, r1-1-1, metatarsus p1-2-2, r1-1-2; IV—tibia d1-0-0, metatarsus p1-2-2, r1-1-2. Abdomen: length 3.37, epigastric furrow 0.77 from tracheal spiracle, spiracle 1.37 from base of spinnerets. Epigynum: hood large; lateral borders sclerotized, thin, and parallel; atrium cylindrical; internally with copulatory ducts short, n-shaped and very wide; seminal receptacles inconspicuou; spermathecae large, oval and posteriorly positioned; fertilization ducts almost as long as spermathecae length ( Fig. 17 View FIGURE 17 B–C).

Natural History. The holotype was collected manually on the necromass of frailejón ( Asteraceae : Espeletia perijaensis Cuatrec. ) in a highly disturbed Páramo ecosystem, at a height of 3200m.
