Pisauridae Simon, 1890

Family | ACCEPTED

N.B.: the Dolomedidae (incl. Bradystichidae) are removed from the synonymy by Morris, Hazzi & Hormiga, 2025: 8, confirmed by Yu et al., 2025: 431 (confirming Lehtinen, 1967: 231, rejecting Sierwald, 1990: 50); Sierwald, 1990: 50 recognized also a "Trechalea genus group [that] is not a close relative of the nursery-web Pisauridae" and whose members are now listed under Trechaleidae; considered a synonym of Halidae Jocqué, 1994b: 281 by Jocqué & Dippenaar-Schoeman, 2006: 212 (confirmed by Polotow, Carmichael & Griswold, 2015); probably includes Senoculidae per Murphy & Roberts, 2015: ix; Morris, Hazzi & Hormiga, 2025: 8 list three subfamilies (Halinae Jocqué, 1994: Hala, Tolma; Thaumasiinae Petrunkevitch, 1928: Architis, Thaumasia; Pisaurinae: Cladycnis, Dendrolycosa, Nilus, Paracladycnis, Perenethis, Pisaura, Pisaurina, Sphedanus) and numerous genera are deemed incertae sedis in terms of their subfamilial placement; Blandinia Tonini, Silva, Filho & Freitas, 2016 is excluded from the Pisauridae by Yu et al., 2025: 431 ("incertae sedis"), but not included into another family.

In synonymy:

Dolopoeus Thorell, 1891 = Nilus O. Pickard-Cambridge, 1876 (Simon, 1898a: 300, sub Thalassius)
