N.B.: removed from the Cyrtaucheniidae and elevated to family level by Bond & Hedin, in Bond et al., 2012b: 10 (considered more closely related to Idiopidae than to other Cyrtaucheniidae); the subfamily name Apomastinae proposed in that paper is a nomen nudum, as no diagnosis was provided.

In synonymy:
Actinoxia Simon, 1891 = Aptostichus Simon, 1891 (Bond & Opell, 2002: 518).
Astrosoga Chamberlin, 1940 = Eucteniza Ausserer, 1875 (Bond & Opell, 2002: 509).
Enrico O. P.-Cambridge, 1895 = Eucteniza Ausserer, 1875 (Bond & Opell, 2002: 509).

N.B.: transferred from the Ctenizidae to the Cyrtaucheniidae by Raven, 1985a: 137, here by Bond & Hedin, in Bond et al., 2012b: 10; considered a senior synonym of Actinoxia Simon, 1891 and Nemesioides Chamberlin, 1919 (which were transferred here from the Ctenizidae by Raven, 1985a: 137; the spelling Nemesioides, used in all previous catalogs, is erroneous) by Bond & Opell, 2002: 518.
