Hemiodus is a genus of halftooths from South America with the greatest species richness in the Amazon Basin, but also found in the Orinoco, Essequibo, Paraná–Paraguay and Parnaíba River basins.[1] Depending on the species involved, these elongate fish reach a length of 7–30 cm (3–12 in).[1]
Fossil remains are known from the Middle Miocene-aged Pebas Formation of Peru.[2]
