N.B.: removed from the synonymy of Troxochrus Simon, 1884; considered a senior synonym of Scleroschema Hull, 1911 by Denis, 1948a: 24, but the type species of that genus was placed by Denis, 1942a: 84 in Silometopus; the synonymy of this genus with Diplocephalus Bertkau, 1883 by Wunderlich, 1970: 407 has not been accepted by later authors; a generic re-organisation of the Savignia group (incl. 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).
