Other material examined. COLOMBIA, Boyacá: Iguape, Quebrada Carrizal , (5°25′12″N; 73°27′24″W), 3360m, ♁1, 17.VIII-15.IX.2000, P. Reina leg. (ICN-Ar-10612) . Cundinamarca: Choachí , 30.IV.2009, ♁1 D. Luna leg. (ICN-Ar-6037) .

Etymology. The specific epithet is a patronym in honor of Martín Ramírez, who has greatly contributed to taxonomic and systematic studies of Neotropical spiders.

Diagnosis. Males of Patrera ramirezi n. sp. can be differentiated from those of the remaining species of the genus by their long retrolateral tibial apophysis, with small dorsal projection ( Fig. 12 C–E). Females are distinguished by their epigynum with exceptionally wide, transversal hood, and transversal copulatory ducts with small seminal receptacles, anteriorly positioned ( Fig. 12 F–G).

Palp: retrolateral tibial apophysis long, ventrally projected; cymbium longer than tibia; subtegulum longer than wide with flattened and apically subrounded distal projection; tegulum longer than wide; median apophysis laminar, short and medially situated; embolus long, apically filiform with narrow base and basally inserted on the tegulum ( Fig. 12 C–E).

Female (AMNH, Paratype). Coloration as in the male ( Fig. 12B ). Total length 5.8, carapace length 2.9, width 2.1. Clypeus height 0.10.
