A small anglerfish recently described from off eastern Australia. Kuiterichthys pietschi resembles the Rough Anglerfish, K. furcipilis, in having a long second dorsal-fin spine and close-set bifurcate (divided) spinules covering the body.
In preservative this species is light brown, paler below, with darker brown marbling and a broad pale band behind the middle of the body. The esca or lure is a single tapering structure with filaments along the sides and a dense cluster of slightly longer filaments arising from the base.
