N.B.: for familial status, use of this younger family-group name (rather than Brachybothriidae Simon, 1892 or Accatymidae Kishida, 1930), and former composition, see Coyle, 1971: 330. Hexura Simon, 1884 transferred from Mecicobothriidae to Antrodiaetidae (Hedin et al., 2019: 14), Hexuridae Simon, 1889 (former syn. of Mecicobothriidae, see Gertsch & Platnick, 1979: 13) now by the same reasons as above (Coyle, 1971: 330) a syn. of Antrodiaetidae.
