Etymology: Cambeva: Probably derived from the Tupi-Guarani, is a popular name for trichomycterid fishes in southern and south-eastern Brazil (Ref. 119381); diffusa: Name from Latin 'diffusa', referring to the color pattern of the species which have diffiuse grey spots, general coloration is lighter compared to its close related congeners..

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal spines: 2; Anal soft rays: 5. This species is distinguished from all its congeners in the C. balios complex by the following characters: with a lighter general colouration, highly differing by the presence of a great concentration of small dark brownish grey dots in a superficial skin layer, contrasting with rounded diffuse pale grey spots, almost inconspicuous, in a deeper layer (vs. never a similar colouration); similar to C. pericoh and differs from C. balios in having a slightly posteriorly folded extremity of the dorsal process of the opercle (vs. unfolded), a narrow postero-dorsal projection on the preopercle (vs. no projection), and branchiostegal rays 8 (vs. 9); differs from C. pericoh in having more dorsal procurrent caudal-fin rays 17 (vs. 13 or 14), fewer ribs 12 (vs. 15), and opercular and interopercular postero-dorsal odontodes distinctively wider and more curved than other odontodes (vs. opercular and interopercular posterodorsal odontodes only slightly wider and more curved than other odontodes) (Ref. 129458).
