Dicymbium is a genus of dwarf spiders that was first described by Anton Menge in 1868. ^[2]

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. ^[3]
