Other material examined. COLOMBIA, La Guajira: Serranía del Perijá, Finca San Jose , 8km SE of Scorpa Mission, (10°00’59”N; 72°57’28”W), 2968m, ♁1, 27–31.VII.1968, B. Malkn leg. ( AMNH); ♁2, 27–31.VII.1968, B. Malkin leg. ( AMNH) GoogleMaps .

Etymology. The specific name is a noun in apposition, a tribute to Yukpa, an Amerindian village situated in the Serranía del Perijá, on both sides of the border between Colombia and Venezuela, which people speaks a language from the northern branch of the Caribbean linguistic family.

Diagnosis. Males of Patrera yukpa n. sp. resemble those of P. florezi n. sp. and P. wiwa n. sp. by having the cymbium similarly shaped, S-shaped, long embolus and bifid retrolateral tibial apophysis ( Figs 16 View FIGURE 16 C–E, 21C–E), but can be distinguished by the very long retrolateral tibial apophysis with both branches similarly-sized, ventral branch rectangular and dorsal branch slender (longer in P. florezi and shorter in P. wiwa ), with duckbill shape in retrolateral view ( Fig. 20 View FIGURE 20 C–E). Females can be distinguished by their short hood, with ondulations at base ( Fig. 20 View FIGURE 20 F–G).

Description. Male (AMNH, Holotype). Carapace brown-reddish anteriorly and posteriorly orange ( Fig. 20A View FIGURE 20 ). Chelicerae, endites, labium, sternum and legs brown-reddish. Abdomen dorsally cream with small orange spots; ventrally white ( Fig. 20A View FIGURE 20 ). Total length 7.65, carapace length 3.4, width 2.6. Clypeus height 0.12. Eye diameters and interdistances: AME 0.10, ALE 0.14, PME 0.12, PLE 0.14; AME–AME 0.04, AME–ALE 0.06, PME–PME 0.20, PME–PLE 0.14, ALE–PLE 0.04.
