[[ Genus Notarius Gill  ZBK  ]]

The family Ariidae is a monophyletic group of siluriform fishes that inhabits marine, brackish, and freshwater environments, and is widespread over the world´s tropical and suptropical continental shelves. The taxonomy of American ariids is in a chaotic state, since many genera lack adequate definition and some valid species remain undescribed or are synonymized. The genus Arius Valenciennes  ZBK  has been widely used to include many western Atlantic (WA) and eastern Pacific (EP) species. However, Betancur-R. (2003) presented phylogenetic evidence based on morphology that demonstrated that the type species of the genus, Pimelodus arius Hamilton  ZBK  from the Indo-West Pacific, has little affinity with American ariid lineages. Although Betancur-R. (2003) did not include the type species of the genus Notarius Gill  ZBK  ( Arius grandicassis Valenciennes  ZBK  ) in his analysis, he proposed its provisional use to group at least 14 neotropical Arius  ZBK  species. Notarius  ZBK  was recently resurrected by Marceniuk and Ferraris (2003), but they included only four species in it.
