Neoechinorhynchus iraqensis sp. n. (Neoechinorhynchidae) is described from the freshwater mullet Liza abu (Heckel, 1843) in the Euphrates River, Iraq. The previous reports of Neoechinorhynchus agilis (Rudolphi, 1819) Van Cleave, 1916, from L. abu as well as from 4 other freshwater fishes in Iraq may refer to the new species. The new species is distinguished from all other species of the genus Neoechinorhynchus by a combination of characters including lemniscal size, inner lining of the body wall, shape of proboscis and neck, and size of proboscis hooks and testes. It is specifically separated from N. agilis by differences in size and shape of trunk, lemnisci, proboscis, proboscis hooks, and testes.
