Patrera pellucida resembles P. tensa by the similar embolus and route of the sperm duct in the tegulum of male palp (as in Figs 11C, 12A, 13B) and by having small hood in the female epigynum (as in Figs 11F, 12C). They differ by the small retrolateral basal projection in the cymbium, retrolateral tibial apophysis sinuous and furrowed in median area in the male palp (Figs 22C–E, 23A, B, 24D, E), and by the small and triangular lateral borders of the female epigynum (Figs 22F, 23C, 24F). Description. Male (IBSP 139447). Carapace and legs orange; chelicerae red brown, with darker distal area; labium and endites orange. Sternum orange, with dark borders. Abdomen dorsally reddish cream with faintly orange paramedian bands, ventrally grayish cream and spinnerets grayish (Fig. 22A). Total length 8.2, carapace length 3.1, width 2.5. Clypeus height 0.10.

Palp: tibia long as cymbium, slightly curved; tibial retrolateral apophysis truncated, curved and serrated on the anterior margin; cymbium oval; tegulum oval, with sperm duct sinuous at base; subtegular projection short, almost all covered by the tegulum; short and almost apical median apophysis; slender prolateral embolus, originating at the base of the tegulum (Figs 22C–E, 23A, B, 24B–E).
