Figures 29 A–E; 33

Type material. Male holotype from Estación Biológica Mosiro Itajúara (Caparú), (1°2′24″S; 69°18′36″W), 200m, Bajo Río Apaporis , Lago Taraira, Vaupés, Colombia, 2.IV.2004, J. Pinzón leg. (ICN-Ar-5882). Paratypes: two males with same data as holotype (ICN-Ar-10637) .

Etymology. The specific epithet refers to the quite long retrolateral tibial apophysis of this species.

Diagnosis. Males of Patrera longitibialis n. sp., can be recognized from those of the remaining species of the genus by their stronger, dome-shape ventral tegular process and by the large retrolateral tibial apophysis, which is as long as the cymbium ( Fig. 29B ̅D).

Description. Male (Holotype, ICN-Ar-5882). Carapace pale brownish, lightest around the fovea ( Fig. 29A ). Chelicerae pale brownish. Labium dark brown with the middle zone lightest, endites pale brownish anteriorly darker in the posterior edges. Sternum pale yellow with a darkest patch on the posterior side. Legs brownish with metatarsi and tarsi darkest than the other segments. Abdomen pale yellow; ventrally darkest from epigastric furrow to tracheal spiracle. Spinnerets pale yellow ( Fig. 29A ). Total length 5.02, carapace length 2.05, width 1.71, high 0.9. Clypeus height 0.07. Eye diameters and interdistances: AME 0.07, ALE 0.11, PME 0.14, PLE 0.14; AME–AME 0.16, AME–ALE 0.24, PME–PME 0.35, PME–PLE 0.34, ALE–PLE 0.29. Chelicerae 0.95 long, three promarginal teeth, six retromarginal teeth. Leg measurements: Leg I—femur 1.95 / patella 0.71/ tibia 2.34/ metatarsus 1.68/ tarsus 0.88/ total 7.58; II—1.76/ 0.7/ 2.07/ 1.46/ 0.71/ 6.71; III—1.33/ 0.51/ 1.08/ 1.37/ 0.52/ 4.83; IV—1.96/ 0.65/ 1.76/ 2.02/ 0.72/ 7.13. Leg spination: I—tibia v2-2-2-2-0, p1-0-1-1, r1-0-1-1, metatarsus v2-2-0-1, p1-1-0-1, r1-1- 0-1; II—tibia v2-2-2-2, p1-1-0-1, r1-0-1-1 ( Fig. 29B ), metatarsus v2-2-0-0, p1-1-0-1, r1-1-0-1; III—tibia d1-0-0-0, v1-2-0-0, p0-1-0-1, r0-0-1-0, metatarsus v2-2-0-0, p1-2-0-2, r1-1-0-2; IV—tibia d1-0-0-0, v1-0-1-0, p1-0-0-1, r1-0- 0-1, metatarsus v2-0-1-1, p1-2-0-2, r1-1-0-2. Abdomen: length 3.16, epigastric furrow 0.76 from tracheal spiracle, spiracle 0.73 from base of spinnerets. Palp: retrolateral tibial apophysis bifid, large, with the ventral branch wider than dorsal branch, which is thin; cymbium longer than tibia; subtegulum longer than wide; tegulum longer than wide, with a strongly sclerotized, wide ventral tegular process closely related to the embolus; median apophysis short, curved and apically situated; embolus short, straight, apically filiform, with narrow base and proximally inserted on the tegulum ( Fig. 29 C–E).

Female. Unknown.

Variation. Males (n=3): total length: 4.99–5.20; carapace length: 2.05–2.73; femur I length: 1.95–2.01.

Natural History. The specimens were collected beating on low vegetation, in a protected forest, at a height of 200 meters.

Distribution. Only known from Amazonas department ( Fig. 33 ).
