Etymology. The specific epithet is a patronym given in honor of Rafael Borja, who has greatly contributed to ecological studies of Neotropical birds, for his support and advice to the first author.

Diagnosis. Males of Patrera borjai   n. sp. resemble those of P. quillacinga   n. sp. and P. perafani   n. sp. by their prominent distal projection of the subtegulum, and a long embolus with narrow base no denticles ( Figs 11 View FIGURE 11 C–E, 9C–E), but can be diagnosed by the embolus with wider base and reduced basal projections (very narrow and no projections in P. quillacinga   and P. perafani   ), and short, ventrally projected, apically truncated retrolateral tibial apophysis (shorter and apically quadrangular in P. quillacinga   , and longer and apically sharp in P. perafani   ) ( Fig. 6C View FIGURE 6 ̅E). Females resemble those of P. quillacinga   by having thin lateral borders, but can be distinguished by lateral borders separated in the medial region, forming two long and narrow atrial cavites, rounded and smaller spermathecae (larger in P. quillacinga   ), and hood with rounded posterior edge ( Fig. 6F View FIGURE 6 ̅G).
