type Dicymbium gracilipes Menge, 1868; gender neuter; syn. of Dicymbium nigrum (Blackwall, 1834)

N.B.: a generic re-organisation of the Savignia group (incl. Araeoncus, Dicymbium, Diplocephalus, Erigonella, Glyphesis) is pending (Frick, Nentwig & Kropf, 2010); Dicymbium is treated as a subgenus in an expanded genus Savignia Blackwall, 1833 by Breitling, 2021: 21, which is not followed here because it is based mainly on COI, see FAQ 7).
