Issue
The dark spots occurring on most scales of the light colored body, usually appearing black or brown, easily identify this species. The type locality for C. callolepis is given as Amazon, the syntypes are aquarium specimens. The type localities for C. nattereri range from Óbidos on the lower Amazon to the mouth of the Rio Negro on the middle Amazon River, possibly overlapping localities. Examination of the types of both indicate C. callolepis to be a synonym of i>C. nattereri. It occurs in the lower to middle Amazon to the Rio Negro then up that river and into the upper Orinoco basin and from the headwater regions of the Rio Branco in Guyana.
