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 View FIGURE 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 View FIGURE 12 F–G).

Description. Male (Holotype, AMNH). Cephalothorax and legs brown-reddish ( Fig. 12A View FIGURE 12 ). Abdomen dorsally gray with dark spots from median to posterior area; ventrally white ( Fig. 12A View FIGURE 12 ). Total length 5.1, carapace length 2.6, width 2.02. Clypeus height 0.08. Eye diameters and interdistances: AME 0.06, ALE 0.10, PME 0.10, PLE 0.06; AME–AME 0.06, AME–ALE 0.06, PME–PME 0.12, PME–PLE 0.08, ALE–PLE 0.02. Chelicerae 0.72 long, four promarginal teeth, six retromarginal denticles. Leg measurements: leg I—femur 2.9/ patella 1.0/ tibia 3.0/ metatarsus 2.7/ tarsus 1.3/ total 10.9; II—2.6/ 1.0/ 1.62/ 2.8/ 1.05/ 9.07; III—1.8/ 0.8/ 1.4/ 1.6/ 0.7/ 6.3; IV—2.63/ 0.8/ 2.15/ 2.8/ 0.9/ 9.28.

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 View FIGURE 12 C–E).

Female (AMNH, Paratype). Coloration as in the male ( Fig. 12B View FIGURE 12 ). Total length 5.8, carapace length 2.9, width 2.1. Clypeus height 0.10. Eye diameters and interdistances: AME 0.06, ALE 0.12, PME 0.14, PLE 0.12; AME– AME 0.04, AME–ALE 0.06, PME–PME 0.16, PME–PLE 0.10, ALE–PLE 0.04. Chelicerae 1.0 long, four promarginal teeth, five retromarginal denticles. Leg measurements: leg I—femur 2.52/ patella 0.9/ tibia 2.5/ metatarsus 2.1/ tarsus 1.0/ total 9.02; II—2.45/ 0.9/ 2.3/ 2.1/ 0.9/ 8.65; III—1.8/ 0.9/ 1.4/ 1.6/ 0.7/ 6.4; IV—2.5/ 0.9/ 2.0/ 2.6/ 0.9/ 8.9.
