Scyphacidae is a family of woodlice in the order Isopoda. It contains 6 genera and about 20 described species in Scyphacidae.
Genera These six genera belong to the family Scyphacidae: Actaecia Dana, 1853 Marioniscus Barnard, 1932 Quelpartoniscus Kwon, 1995 Scyphacella Smith, 1873 Scyphax Dana, 1853 Scyphoniscus Chilton, 1901
Taxonomy The genus Scyphoniscus was moved by Schmidt (2002) from Scyphacidae to Detonidae, and this combination was reflected in a catalogue by Schmalfuss (2003). However, in a more recent paper (Schmidt & Leistikow 2004: Catalogue of genera of the terrestrial Isopoda. - Steentstrupia 28: 1-118) the genus was included again in Scyphacidae.
