N.B.: for comments on relationships, see Michalik & Hormiga, 2010: 7; re-synonymization of Pimoidae (Murphy & Roberts, 2015: ix) not sufficiently justified and is not accepted here; Sinopimoidae Li & Wunderlich, 2008 [urn:lsid:nmbe.ch:spiderfam:0112] synonymyized with Linyphiidae by Dimitrov et al., 2017: 245; resurrection of Sinopimoidae by Wunderlich, 2020b: 20 is not accepted here, because Dimitrov et al., 2017 was not taken into account; re-elevation of Sinopimoidae to family level by Eskov & Marusik, 2023: 343 not accepted here (by majority vote of the WSC boards); the current status of Sinopimoidae is also maintained for reasons of stability and we wait for a probable confirmation or rejection of this resurrection; other subfamilies are Erigoninae Emerton, 1882: 7 and Mynogleninae Lehtinen, 1967: 250.
