Lasiognathus amphirhamphus is a species of marine ray-finned fish belongning to the family Thaumatichthyidae, the wolftrap anglers. This species was first formally described in 2005 by the American ichthyologist Theodore Wells Pietsch III and is known from a single Zoological specimen, the holotype, collected from the Madeira Abyssal Plain in the east-central Atlantic Ocean where it occurs at a depth of from 1,200 to 1,305 metres. The holotype, a female, had a standard length of 15.7 cm (6.2 in). This species is characterized by having only two bony hooks on its esca, which are lightly pigmented.
