[1] Spiders in the family are easily identified by the greatly elongated base of the piriform gland spigots.
The posterior median eyes are flat and silvery, with a triangular, egg-shaped or irregularly rectangular shape.
Although Theuma walteri was described from Turkmenistan by Eugène Simon, it is suspected that Simon accidentally exchanged its locality with that of Anagraphis pallens (Gnaphosidae); then T. walteri would have been collected in the Cape of Good Hope, while A. pallens is from Turkmenistan.
[3] Genera included:[1] A 2020 phylogenetic analysis involving 59 species of Prodidominae and 32 outgroup species did not recover Prodidominae as monophyletic because Anagrina did not arise within the subfamily.
[4] The study re-established Molycriinae (including genera Cryptoerithus, Molycria, Nomindra, Wesmaldra, and Wydundra) as a distinct subfamily in Gnaphosidae, a sister to Prodidominae.
