Diagnosis. 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 ).

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 ).
