Scyphacidae

Scyphacidae is a family of woodlice in the order Isopoda. There are about 7 genera and more than 30 described species in Scyphacidae.

Genera
These seven genera belong to the family Scyphacidae:
 * Actaecia Dana, 1853
 * Haloniscus Chilton, 1920
 * 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.
