Dicymbium is a genus of dwarf spiders that was first described by Anton Menge in 1868.
The etymology of the genus is based on the appearance of the male palp. The palpal tibia bears an elongated, broad, cup-shaped projection that surrounds the cymbium proper dorsally. Hence, Menge chose to name the genus Dicymbium, literally meaning two cymbia/a double cymbium.
Species it contains eight species and one subspecies: Dicymbium elongatum (Emerton, 1882) – USA, Canada Dicymbium facetum (L. Koch, 1879) – Russia (Urals to Far East), Mongolia Dicymbium libidinosum (Kulczyński, 1926) – Russia (Middle Siberia to Far East), China Dicymbium nigrum (Blackwall, 1834) (type) – Europe, Turkey, Caucasus, Russia (Europe to South Siberia), Kazakhstan, Kyrgyzstan, China Dicymbium n. brevisetosum Locket, 1962 – Europe Dicymbium salaputium Saito, 1986 – Japan Dicymbium sinofacetum Tanasevitch, 2006 – China Dicymbium tibiale (Blackwall, 1836) – Europe Dicymbium yaginumai Eskov & Marusik, 1994 – Russia (Far East), Japan
