Malthopsis is genus of relatively small deep-water batfishes with a depressed triangular-shaped body covered in large spiny cone-shaped scales or bucklers. Species have large subopercular spines, the cranium somewhat elevated above the body disc, a very small conical rostrum and a small mouth. The esca (fishing lure) is a small bulb. Tiny tubercles cover the tough skin between the bucklers and there is no membrane between the arm-like pectorral-fin bases and the body.
