N.B.: considered a senior synonym of Prosoponcus Simon, 1884a: 569 [urn:lsid:nmbe.ch:spidergen:05362] (type Walckenaeria cristatus Blackwall, 1833) by Simon, 1894a: 656; considered a senior synonym of Plaesiocraerus Simon, 1884a: 745 [urn:lsid:nmbe.ch:spidergen:05364] (type Walckenaera latifrons O. Pickard-Cambridge, 1863) (itself not a senior synonym of Monocephalus Smith, 1906), of Streptosphaenus Simon, 1926: 384, 497 [urn:lsid:nmbe.ch:spidergen:05365] (type Diplocephalus adjacens O. Pickard-Cambridge, 1903 = D. connatus Bertkau, 1889) by Denis, 1949a: 140, of Chocorua Crosby & Bishop, 1933b: 164 [urn:lsid:nmbe.ch:spidergen:05363] (type Lophocarenum cuneatum Emerton, 1909) by Hackman, 1954: 28 and of Hemistajus Schenkel, 1934: 90 [urn:lsid:nmbe.ch:spidergen:06060] (type Diplocephalus rostratus Schenkel, 1934) by Thaler, 1970: 256 (by transfer of the type species; Hemistajus was described as subgenus of Diplocephalus and elevated to genus by Schmölzer, in Janetschek, 1956: 479); for illustrations of the modified male carapace and a phylogenetic tree of six European species, see Schaible & Gack, 1987; a generic re-organisation of the Savignia group (includes Araeoncus, Dicymbium, Diplocephalus, Erigonella, Glyphesis) is pending (Frick, Nentwig & Kropf, 2010); the proposed synonymy with Savignia Blackwall, 1833 by Breitling, 2021: 22 is not followed here as it is based mainly on COI (see FAQ 7).
