Tomlin, 1927[1]

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 Children, 1834 and Thiaridae Gill, 1871 (1823).[3] Houbrick (1979) brought the then known species of Abyssochrysos in the superfamily Loxonematacea Koken, with close affinities to the families Zygopleuridae Wenz, 1939, Paleozygopleuridae Horny, and Pseudozygopleuridae Knight, 1930.[4]

Distribution
  • The type specimen was dredged from a depth of 1645 m to 1828 m off the Cape of Good Hope, South Africa.
  • Philippines[5]
  • Indonesia[5]
