Abyssochrysos melanioides is a species of sea snail, a marine gastropod mollusk in the family Abyssochrysidae.
This is the type specimen for which Tomlin created a new family Abyssochrisidae, but couldn't refer at the time to any superfamily. Some years later he thought it had any affinities with the families Littorinidae <small>Children, 1834</small> and Thiaridae <small>Gill, 1871 (1823)</small>. Houbrick (1979) brought the then known species of Abyssochrysos in the superfamily Loxonematacea <small>Koken</small>, with close affinities to the families Zygopleuridae <small>Wenz, 1939</small>, Paleozygopleuridae <small>Horny</small>, and Pseudozygopleuridae <small>Knight, 1930</small>.
