Superorder Gliriformes Wyss and Meng, 1996

Comment.—The superorder “ Anagalida ” traditionally comprises the Macroscelidea (elephant shrews) and the Glires (rodents, lagomorphs and related forms), as well as a number of extinct families of uncertain affinities ( McKenna and Bell 1997). Because several studies suggest Macroscelidea do not have close affinities with Glires ( Zack et al. 2005; Tabuce et al. 2006), we prefer to use the term Gliriformes ( Meng and Wyss 2001) to designate Glires and a number of closely related, extinct families. The latter traditionally include Zalambdalestidae , Anagalidae , and Pseudictopidae ( McKenna and Bell 1997) , but probably also Astigalidae ( Hu 1993; Tong and Wang 2006) and Arctostylopidae ( Missiaen et al. 2006) .
