N.B.: Includes Aphantochilidae as "a subfamily related to the Strophiinae" (Ono, 1988c: 217-218, after Homann, 1975: 184; see also Benjamin, 2011: 8 and Teixeira, Campos & Lise, 2014: 73). Separation of Borboropactidae Wunderlich, 2004 (Wunderlich, 2004m: 1738, Murphy & Roberts, 2015: viii) not sufficiently justified and is not accepted here. Lehtinen, 2016 splits the family into five families, i.e. Thomisidae s. str., Borboropactidae Wunderlich, 2004, Stephanopidae O. Pickard-Cambridge, 1871, Stiphropidae Simon, 1886 [sub Stiphropodidae; for nomenclatural author and year see Simon, 1886b: 170] and Bomidae Simon, 1886 [for nomenclatural author and year see Simon, 1886b: 173]; because of lack of a phylogenetic analysis and partly unclear limitations this splitting is not accepted; the family is not monophyletic per Kulkarni, Wood & Hormiga, 2023: 518, f. 17-18.
