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:

Blaniargus Simon, 1913 = Micrargus Dahl, 1886 (Denis, 1950a: 248)

Nothocyba Simon, 1926 = Micrargus Dahl, 1886 (Denis, 1949a: 142, sub Blaniargus)

Plexisma Hull, 1920 = Micrargus Dahl, 1886 (Denis, 1949a: 142, sub Blaniargus)

Gen. Micrargus Dahl, 1886 urn:lsid:nmbe.ch:spidergen:01095

N.B.: considered a senior synonym of Blaniargus Simon, 1913: 365 [urn:lsid:nmbe.ch:spidergen:05429] (type B. cupidon Simon, 1913) by Denis, 1950e: 248; Blaniargus was considered a senior synonym of Nothocyba Simon, 1926: 440, 517 [urn:lsid:nmbe.ch:spidergen:05430] (type Erigone subaequalis Westring, 1851) by Denis, 1949a: 142); Nothocyba is an objective junior synonym of Plexisma Hull, 1920a: 10 [urn:lsid:nmbe.ch:spidergen:04157] (type Erigone subaequalis Westring, 1851); Wunderlich's (1970: 406) synonymy of Micrargus with Ceratinopsis Emerton, 1882 has not been accepted by later authors.
