Affinities. Removal of the Penestominae  from the Eresidae  HNS  was justified by analysis of molecular sequence data (Miller et al. 2010). These data consistently indicated that penestomines are close to the Zodariidae  HNS  , and that this relationship has significantly better support than one constrained to include a monophyletic Eresidae  HNS  including Penestominae (Shimodaira & Hasegawa 1999)  . One line of morphological evidence that could support a close relationship between zodariids and penestomids has to do with the arrangement of spigots on the anterior lateral spinnerets. Typically, the major ampullate gland spigots ( MAP) are placed on the margin of the spinning field (e.g. see Griswold et al. 2005, fig. 49 B) but in both zodariids (Miller et al. 2010, fig. 2 E) and penestomids (Fig. 6 B) the MAP are placed in the center of the field of piriform gland spigots ( PI).

The Zodariidae  HNS  are diagnosed by several characters not found in Penestominae  (i.e. absence of serrula, lateral implantation of tarsal claw teeth, long anterior lateral spinnerets; see Jocqu√© 1991). Inclusion of Penestominae  within the entirely ecribellate Zodariidae  HNS  would radically change and complicate the diagnosis of this expanded family concept. For these reasons, Miller et al. (2010) promoted Penestominae  to family rank.
