Synonymy. We associate males and females through material collected from Meta department, Colombia.

Diagnosis. Males of Patrera armata   can be distinguished from the remaining species by the males having a large dorsobasal bump on the palpal tibia ( Fig. 22C View FIGURE 22 , arrow), bifid retrolateral tibial apophysis with dorsal branch thin and very wide ventral branch, and curved, slender embolus on an apical tegular furrow ( Fig. 22 View FIGURE 22 B–E). Females can be reconigzed by the M-shaped lateral borders, large and oval seminal receptacles, and thin, strongly sclerotized hood ( Fig. 22 View FIGURE 22 G–H).
