Other material examined. COLOMBIA, Magdalena: Sierra Nevada de Santa Marta, San Pedro de La Sierra, Hacienda Hierba Buena (10°53′27.3″N; 73°59′43.9″W), 2040m, ♁7, 10.XI.2015, L. Martínez leg. (ICN-Ar-10650); San Sebastian de Rabago (10°34′0.08″N; 73°35′59.95″W), 2000m, ♁2, 1-10.IV.1968, B. Malkin leg. (AMNH); ♀ 2, 1-10.IV.1968, B. Malkin leg. (AMNH).
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 C–E). Females resemble those of P. carvalhoi n. sp. by the epigynal plate with lateral border curved in the anterior region (Fig. 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 F–G).
Description. Male. (Holotype, ICN-Ar-9661). Carapace brownish, darker on the cephalic region (Fig. 13A). Chelicerae dark brown. Labium and endites brown. Sternum yellowish. Legs yellow, darkest from tibiae to tarsi. Abdomen dorsally grayish; ventrally yellow (Fig. 13A). Spinnerets yellow. Total length 6.76, carapace length 3.27, width 2.41, high 0.84.
