N.B.: For the name Drassidae see Simon, 1893a: 340. Family relimited by Platnick, 1990a: 35 and Azevedo, Griswold & Santos, 2018b: 612. Most genera listed by Brignoli under Micariinae are treated here under Corinnidae and Phrurolithidae. Prodidomidae revalidated by Platnick, 1990a: 36 to include the former Prodidominae, Molycriinae and Anagraphidinae. Anagraphidinae transferred from Prodidomidae to Gnaphosidae by Platnick & Baehr, 2006: 5. Prodidomidae are downgraded to subfamily of Gnaphosidae by Azevedo, Griswold & Santos, 2018b: 613. Azevedo, Griswold & Santos, 2018b: 612 distinguish several well definded clades within Gnaphosidae (Gnaphosinae Pocock, Zelotinae Platnick, Herpyllinae Platnick, Drassodinae Simon, Prodidominae Simon and Leptodrassinae subfam. nov.) and state monogeneric subfamilies, Anagraphidinae (type genus Anagraphis), Echeminae (Echemus) and Micariinae (Micaria), which do not perform a grouping function. Micaria Westring 1851, Nauhea Forster, 1979 and Verita Ramirez & Grismado, 2015 (and some related genera) are probably not gnaphosids, and many genera are not assigned to a subfamily given their poorly supported and unstable relationships (Azevedo, Griswold & Santos, 2018b: 614).
