N.B.: For the family name Drassidae Sundevall, 1833 see Simon, 1893a: 340 and Bonnet, 1956: 1554. Family relimited by Platnick, 1990a: 35 and Azevedo, Griswold & Santos, 2018b: 612. Most genera listed by Brignoli, 1983c 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 (synonyms: Molycriinae Platnick, 1990 and Theuminae Platnick & Baehr, 2006). Azevedo, Griswold & Santos, 2018b: 612 distinguish several well definded clades within Gnaphosidae (Gnaphosinae Pocock, 1898, Zelotinae Platnick, 1990, Herpyllinae Platnick, 1990, Drassodinae Simon, 1893, Prodidominae Simon, 1884 and Leptodrassinae Azevedo, Griswold & Santos, 2018) and state three monogeneric subfamilies, Anagraphidinae Simon, 1893 (type genus Anagraphis), Echeminae Simon, 1893 (type genus Echemus) and Micariinae Simon, 1897 (type genus 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).
