Axelrodia stigmatias

Axelrdodia stigmatias was first formally described as Hyphessobrycon stigmatias in 1913 by the American zoologist Henry Weed Fowler, with its type locality given as a tributary of the Rio Madeira near Porto Velho in Brazil. A. fowleri is now considered to be a synonym of H. stigmatias. ==Etymology==
