One variation of the species with clear white regular spots on jet black is called the Black Diamond Ray. There are currently only two other species of South American river ray with a black background and white spots: the Big-tooth River Stingray, P. henlei, of the Rio Tocantins basin, Brazil, similar to the Black Diamond variant but also may have more yellow-golden spots or a greyer base, and the Itaituba/Tapajós River Stingray, P. albimaculata, defined in 2016, which has more but smaller white spots.
