The mountain ranges of southeastern and southern Brazil are inhabited by a great diversity catfishes the genus Cambeva. Cambeva variegata group, diagnosed having prominent skin crest similar to an adipose fin, interrupted supraorbital laterosensory canal, with additional S4 pore, relatively small premaxilla accentuated constriction on its lateral portion, occurs in broad area south-eastern Brazil, mostly within savannah-like Cerrado vegetation at northern-most part distribution. new species described here was collected streams Rio das Velhas drainage, São Francisco basin, draining Serra do Espinhaço. is more interopercular odontodes combination morphometric data, colour pattern, relative dorsal-fin origin vertebra position, and-fin-ray morphology. Field studies indicate that two localities where occur being dramatically affected negative human impacts, putting it severe risk extinction.
