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 View FIGURE 6 ̅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 View FIGURE 9 ̅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 View FIGURE 8 ̅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 View FIGURE 9 ̅G).
