Figures 26A–F ; 33

Type material. Male holotype from Reserva Natural Río Ñambí (1°14′45.22″N; 78°6′54.71″W), 1440m, Barbacoas, Vereda Altaquer Nariño, Colombia, 09.IV.2010, E. Flórez et al leg. (ICN-Ar-10636) .

Etymology. The specific epithet is referring to the ventral projection of the chelicerae.

Diagnosis. Males Patrera dentata n. sp. can be distinguished from those of the remaining species of the genus by the slender, elongated ventral tegular apophysis closely related to the embolus and by the presence of a second triangular, small tegular projection ( Fig. 26D ̅F).

Description. Male (Holotype, ICN-Ar-10636). Carapace from cephalic zone to thoracic groove pale brown, lateral and posterior margin yellow ( Fig. 26A ). Chelicerae red brownish ( Fig. 26A ). Labium and endites brown. Sternum yellow. Legs yellow. Abdomen gray covered of black setae; ventrally light gray. Spinnerets yellow ( Fig. 26A ). Total length 6.53, carapace length 2.81, width 2.17, high 0.95. Clypeus height 0.13. Eye diameters and interdistances:AME 0.09, ALE 0.19, PME 0.18, PLE 0.21; AME–AME 0.21, AME–ALE 0.37, PME–PME 0.5, PME–PLE 0.47, ALE–PLE 0.39. Chelicerae 1.56 long, three promarginal teeth, the second largest, four retromarginal teeth; Cavp large ( Fig. 28C ). Leg measurements: Leg I—femur 4.12/ patella 1.17/ tibia 4.72/ metatarsus 4.0/ tarsus 2.03/ total 16.05; II—lost; III—lost/ 0.95/ 2.38/ 2.76/ 1.05/ 7.16; IV—3.61/ 1.18/ 3.41/4.19/ 1.47/ 13.76. Leg spination: I—tibia v2-2-0, p0-1-1, metatarsus v2-1-0; II—lack; III—tibia d1-0-0 v2-2-0, p1-0-1, r1-0-1, metatarsus v2-2-0, p1-2-2, r1-1-2; IV—tibia d1-0-0, p1-0-1, r1-0-1, metatarsus d1-0-0, v2-2-1, p1-2-2, r1-1-2. Abdomen: length 3.49, epigastric furrow 0.93 from tracheal spiracle, spiracle 1.35 from base of spinnerets. Palp: retrolateral tibial apophysis bifid, large, with the ventral branch longer than dorsal branch; cymbium shorter than tibia length; subtegulum longer than wide; tegulum longer than wide, with a sclerotized, thin ventral tegular process closely related to the embolus, and a second triangular projection; median apophysis short, curved, laminar and apically situated; embolus short, apically filiform, with narrow base and proximally inserted on the tegulum ( Fig. 26 D–F).

Female. Unknown.

Distribution. Only known from the Nariño department ( Fig. 33 ).
