N.B.: the names Gnaphosae and Gnaphosi were used firstly at tribe level by
Banks, 1892d: 92, 94 and thus Banks, 1892 is the valid authorship and year for the family, not
Pocock, 1898c: 219; 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 downgraded to subfamily of Gnaphosidae by
Azevedo, Griswold & Santos, 2018b: 613 (synonyms: Molycriinae Simon, 1897 and Theuminae Simon, 1893), redefined by
Rodrigues & Rheims, 2020b: 694 and elevated to familiy rank again by
Azevedo et al., 2022: 12 (without Molycriinae);
Azevedo, Griswold & Santos, 2018b: 612 distinguish several well definded clades within Gnaphosidae (Gnaphosinae Banks, 1892, 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 Banks, 1892 (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); the subfamily Molycriinae Simon, 1897 is re-established by
Rodrigues & Rheims, 2020b: 682 (includes
Cryptotoerithus,
Molycria,
Myandra,
Nomindra,
Wesmaldra and
Wydundra);
Lin & Li, 2020e: 313 described the new subfamily Solitudinae, with the single genus
Solitudes Lin & Li, 2020; Micariidae is regarded as a separate family (sister to Cithaeronidae) by
Breitling, 2021: 19, but without listing the genera, which should belong to it, and it is also not accepted because it is based mainly on COI, see
FAQ 7; Ammoxenidae (
Ammoxenus,
Austrammo,
Barrowammo,
Rastellus) are synonymized with Gnaphosidae by
Azevedo et al., 2022: 12; the family is not monophyletic per
Kulkarni, Wood & Hormiga, 2023: 520, f. 19.
