The male of Cambonilla symphonia gen. et sp. nov. is recognized by the presence of stridulating organs on Fe I and II, and by the strong tapered RTA on the palp, the female by the epigyne with very deeply incised central plate.
The species name ‘ symphonia ’ is a noun in apposition meaning ‘orchestra’ and refers to the four stridulating organs on the femora of the male.
