Argyronetidae Thorell, 1869

Family | ACCEPTED

N.B.: the family is separated from the Dictynidae and re-definded by Montana et al., 2025: 9 to include 12 genera, Argyroneta probably represents an own subfamily; Argyronetidae were seperated before (Ono, 2009a: 169, Murphy & Roberts, 2015: viii, with the single genus Argyroneta), but this was not accepted.
