Type material. Male holotype from Parque Nacional Natural Las Orquídeas (6°37′15.4″N; 76°8′46.1″W), 3456m, Vereda Piedras, Sector La Mina cuchilla hacia Morropelao, Frantini, Antioquia, Colombia, 2.II.2012, W. Galvis, leg. (ICN-Ar-5673).
Etymology. The specific epithet is a patronym in honor of Dr. Norman Platnick, for his contribution to taxonomy of the spiders of the world.
Diagnosis. Males of Patrera platnicki n. sp. resemble those of P. barbacoas n. sp., by having the abdomen with several dark patches and subsquare retrolateral tibial apophysis (Fig. 5B ̅D), but can be diagnosed by their large and apically squared retrolateral tibial apophysis (smaller and thinner in P. barbacoas), and embolus inserted subbasally on the tegulum with rounded base (basally originating on the tegulum and with narrow base in P. barbacoas) (Fig. 10B ̅D).
Description. Male. (Holotype, ICN-Ar-5673). Carapace brown, darker on the cephalic region and thoracic groove (Fig. 10A). Chelicerae dark brown. Labium and endites brown. Sternum brown. Legs yellow, darkest from tibiae to tarsi. Abdomen grayish with very black setae, and four black posterior transversal bands; ventrally yellow. Spinnerets yellow (Fig. 10A). Total length 8.55, carapace length 3.69, width 3.22, high 1.49. Clypeus height 0.07. Eye diameters and interdistances: AME 0.15, ALE 0.22, PME 0.2, PLE 0.3; AME–AME 0.34, AME–ALE 0.49, PME–PME 0.56, PME–PLE 0.54, ALE–PLE 0.56. Chelicerae 1.9 long, five promarginal teeth, six retromarginal denticles.

Abdomen: length 4.29, epigastric furrow 1.02 from tracheal spiracle, spiracle 1.0 from base of spinnerets. Palp: retrolateral tibial apophysis large, apically square and apically serrate; cymbium longer than tibia; subtegulum longer than wide with subrounded distal projection; tegulum longer than wide; median apophysis very short, curved and basally situated; embolus long, thin with rounded base, apically filiform and subbasally inserted on the tegulum (Fig. 10 B–D).
