Figures 9A–G; 30
Type material. Male holotype from Mistrato, Manpay, Quebrada Sutu y Empalado (5°22′42.14″N; 75°53′14.24″W), 1830m, Risaralda, Colombia, 3.IV.1992, M. Rocha & G. Andrade leg. (ICN-Ar-10602). Paratypes: female from Mistrato, San Antonio del Chamei, Palestina (5°25′2.49″N; 75°54′10.05″W), 1150m Risaralda, Colombia, 30.III.1992, M. Rocha leg. (ICN-Ar-5429).
Etymology. The specific epithet is a patronym in honor of Carlos Perafán, for his contributions to the taxonomic studies of Neotropical Mygalomorphae spiders.
Diagnosis. Males of Patrera perafani n. sp. resemble those of P. borjai n. sp. and P. quillacinga n. sp. by having a long embolus devoid of basal projections or denticles (Figs 6C ̅E, 11C̅E), but differs by having longer and thin retrolateral tibial apophysis, slightly curved and apically sharp (wider and shorter in P. quillacinga and shorter and apically truncated in P. borjai) (Fig. 9C ̅E). Females resemble those of P. ruber and P. dimar n. sp. by the short and wide lateral borders, short copulatory ducts, and large spermathecae (Fig. 8F ̅G; Brescovit 1997: 147, figs 55̅56), but can be diagnosed by the triangular, thin hood and rounded, small spermathecae (larger in P. ruber and P. dimar) (Fig. 9F ̅G).
