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) .

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 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 C–E). Females can be distinguished by their short hood, with ondulations at base ( Fig. 20 F–G).

Description. Male (AMNH, Holotype). Carapace brown-reddish anteriorly and posteriorly orange ( Fig. 20A ). Chelicerae, endites, labium, sternum and legs brown-reddish.

Abdomen: length 4.1, epigastric furrow 1.1 from tracheal spiracle, spiracle 1.8 from base of spinnerets. Palp: retrolateral tibial apophysis bifid and long, with branches of equal length and a thin furrow along of the ventral branch; cymbium shorter than tibia with protuberant tutacular groove; subtegulum longer than wide, with conspicuous distal projection; tegulum longer than wide; median apophysis long, curved and medially situated; embolus long, apically filiform, with narrow base and basally inserted on the tegulum ( Fig. 20 C–E).

Female (Paratype, ICN-Ar-10648). Coloration deteriored because the specimen suffered dehydratation ( Fig. 20B ). Total length 4.42, carapace length 2.31, width 1.17. Clypeus height 0.07.
