Family Miturgidae Simon, 1886

Diagnosis (following Raven & Stumkat 2003): Two-clawed lycosoid spiders with grate-shaped tapetum (Fig. 14 a, inset) and RTA of male with unsclerotised portion (e.g., Figs. 6 c, 14e). Eyes in two rows with posterior row slightly procurved to recurved (e.g., Fig 1c). Male pedal tibiae without basal fracture zone.

Remarks: This diagnosis specifically excludes Cheiracanthium and other Eutichurinae which do not have a grate-shaped tapetum or the unsclerotised section of the RTA; the Eutichurinae are considered more closely related to the Clubionidae (see Introduction).

Until version 8.5 of the Platnick catalog of spiders of the world, the year of creation of the Miturgini was considered to be 1885 but has since been corrected to 1886 (Platnick, 2008).
