Linyphiidae Blackwall, 1859

Family |   ACCEPTED
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.

In synonymy:

Otunus Chikuni, 1955 = Arcuphantes Chamberlin & Ivie, 1943 (Yaginuma, 1970d: 651, by T of the type species)

Gen. Arcuphantes Chamberlin & Ivie, 1943 urn:lsid:nmbe.ch:spidergen:00843
N.B.: considered a senior synonym of Otunus Chikuni, 1955: 29 [urn:lsid:nmbe.ch:spidergen:05390] (type O. delicatus Chikuni, 1955) by Yaginuma, 1970d: 651; Otunus was regarded a nomen nudum by Yaginuma, in Brignoli, 1983c: 285; Arcuphantes is not a senior synonym of Fusciphantes Oi, 1960 (Saaristo, Tu & Li, 2006: 387, contra Oi, 1964: 23, but see also Tanasevitch, 2010d: 269 and Nakano et al., 2017: 333); the new species described in Nakano et al., 2017 are assigned to the Arcuphantes longiscapus species group and therefore included here in the genus Fusciphantes.
