The dorsal surface of the abdomen is pale brown to beige and has a variable darker folium (leaf-like) pattern.

The ventral surface is variable but is usually darkest in the middle and has lateral pale bands that may be elongate, ovoid, or spindle-like in shape.

[2] Salsa can be distinguished from similar spider genera by the abdomen having a single posterior tubercle and ventral pale bands.

In males, the pedipalp has a C-shaped median apophysis and teeth-like tubercles inside its basal arch.

[2] Many of these species were previously assigned to other genera, such as Araneus, Cyclosa or Epeira.
