Radulphius strandi Caporiacco, 1947 a: 26 (Female holotype from Guyana, deposited in the Museo Zoologico de “La Specola”, examined); Caporiacco 1948 a: 672, fig. 86. New synonymy.

Aysha strandi: Caporiacco 1955: 391 .

Patrera armata: Brescovit 1997: 33 .

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, 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 B–E). Females can be reconigzed by the M-shaped lateral borders, large and oval seminal receptacles, and thin, strongly sclerotized hood (Fig. 22 G–H).
