''Abyssochrysoidea'' is a superfamily of deep-water sea snails, marine gastropod mollusks in the clade Caenogastropoda. These marine snails are part of the fauna of the hydrothermal vents and other deep-water habitats. ==Families== Families within the superfamily Abyssochryoidea include: * Abyssochrysidae Tomlin, 1927 * Provannidae Warén & Ponder, 1991 * Hokkaidoconchidae (extinct) * unassigned : one genus ''Rubyspira'' Johnson, Warén, Lee, Kano, Kaim, Davis, Strong & Vrijenhoek, 2010 These two families Provaniidae and Abyssochrysidae were previously placed in the "Zygopleuroid group" (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). Subsequently Provannidae was placed in the superfamily Abyssochrysoidea by Kaim et al. (2008)〔Kaim A., Jenkins R. G. & Warén A. (2008). "Provannid and provannid−like gastropods from Late Cretaceous cold seeps of Hokkaido (Japan) and the fossil record of the Provannidae (Gastropoda: Abyssochrysoidea)". ''Zoological Journal of the Linnean Society'' 154(3): 421-436. .〕 and then Abyssochrysidae was also moved to Abyssochrysoidea.〔WoRMS (2009). Abyssochrysidae. In: Bouchet, P.; Gofas, S.; Rosenberg, G.
