Etymology. The epithet is a noun in apposition honoring to the Quillacinga, indigenous people who lived in the Nariño department region, the type locality.

Diagnosis. Males of Patrera quillacinga n. sp., resemble those of P. borjai n. sp. by their embolus and its base unprovided of denticles and short retrolateral tibial apophysis ( Figs 6 View FIGURE 6 C–E), but can be diagnosed by their very short and quadrangular retrolateral tibial apophysis (longer and apically truncated in P. borjai , and longer and apically sharp in P. perafani ), and embolus with the base not projected ( Fig. 11 View FIGURE 11 C–E). Females resemble those of P. anchicaya by their thin lateral borders ( Fig. 4 View FIGURE 4 F–G), but can be distinguished by the short hood (larger in P. anchicaya ), very large spermathecae (smaller in P. anchicaya ), and thin lateral borders, anteriorly fused delimiting two atrial cavities with rounded anterior edges ( Fig. 11 View FIGURE 11 F–G).
