Etymology. The specific epithet is a patronym in honor to arachnologist Alexandre B. Bonaldo, for his contributions to taxonomic studies of Neotropical spiders.

Diagnosis. Males of Patrera bonaldoi n. sp. can be recognized by having both branches of retrolateral tibial apophysis short and truncated, by the laminar-shaped, very long embolus with filiform apex and by the membranous ventral tegular process ( Fig. 13 View FIGURE 13 C–E). Females resemble those of P. carvalhoi n. sp. by the epigynal plate with lateral border curved in the anterior region ( Fig. 15 View FIGURE 15 F–G), but differs by the long and thick hood (triangular in P. carvalhoi ), thin and sinuous copulatory ducts (wide in P. carvalhoi ), and oval spermathecae (bean-shaped in P. carvalhoi ) ( Fig. 13 View FIGURE 13 F–G).

Description. Male. (Holotype, ICN-Ar-9661). Carapace brownish, darker on the cephalic region ( Fig. 13A View FIGURE 13 ). Chelicerae dark brown. Labium and endites brown. Sternum yellowish. Legs yellow, darkest from tibiae to tarsi. Abdomen dorsally grayish; ventrally yellow ( Fig. 13A View FIGURE 13 ). Spinnerets yellow. Total length 6.76, carapace length 3.27, width 2.41, high 0.84. Clypeus height 0.12. Eye diameters and interdistances:AME 0.13, ALE 0.15, PME 0.15, PLE 0.15; AME–AME 0.29, AME–ALE 0.31, PME–PME 0.46, PME–PLE 0.42, ALE–PLE 0.45.

Abdomen: length 3.25, epigastric furrow 0.94 from tracheal spiracle, spiracle 1.38 from base of spinnerets. Palp: retrolateral tibial apophysis bifid, short and with both branches apically truncated, dorsal branch wider than the ventral one; cymbium twice longer than tibia; subtegulum longer than wide, thin, with the distal projection inconspicuous; tegulum longer than wide with a membranous and laminar distal projection; median apophysis very short, apically situated; embolus long, laminar, apically filiform with narrow base and basally inserted on the tegulum ( Fig. 13 View FIGURE 13 C–E).

Female (Paratype, AMNH). Carapace and cephalic region yellow ( Fig. 13B View FIGURE 13 ). Chelicerae yellow. Labium, sternum and endites yellow. Abdomen grey ( Fig. 13B View FIGURE 13 ). Spinnerets yellow. Total length 5.9, carapace length 2.6, width 1.9. Clypeus height 0.08.

Epigynum: hood large, wide and posteriorly projected; lateral borders sclerotized, thin, semicircular and extended over the epigynal atrium; atrium extremely short; internally with copulatory ducts long and thin; seminal receptacles small, rounded and anteriorly situated on the copulatory ducts; spermathecae large, oval with an anterior extension and posteriorly positioned; fertilization ducts shorter than spermathecae ( Fig. 13 View FIGURE 13 F–G).

Variation. Males (n=8): total length: 5.70–6.76; carapace length: 3.00–3.45; femur I length: 2.36–3.01.

Natural History. The type specimens were collected beating low shrubs, in a conserved high mountain wet forest ecosystem, together with the specimens of P. florezi n. sp., at an elevation between 1563–5130m.

Distribution. Only known from Magdalena department ( Fig. 32 View FIGURE 32 ).
