Males of Diores russelli have a total length of 3.17 mm, while females measure 4.29 mm. The carapace is yellow with a black eye field and is slightly suffused with grey on the clypeus. The sternum is pale yellow, and the chelicerae and legs are yellow. The opisthosoma is pale sepia with a pale yellow scutum in the anterior half of the dorsum, followed by two sepia longitudinal bands with sinuous edges. Females have similar coloration but lack the dorsal scutum.
