Etymology: Cambeva: Probably derived from the Tupi-Guarani, is a popular name for trichomycterid fishes in southern and south-eastern Brazil (Ref. 119381); duplimaculata: Derived from the Latin word (doubly maculated) which refers to its coloration patter in the flank: two overlapped spotted patterns in different skin layers (inner large black spots and outer small brown spots) (Ref. 129458).
