The abdomen has a large leaf-like pattern, which differentiates it from other species in the genus, as can the yellowish-orange colour of the pedipalps on the male.

The female has a unique epigyne that led Wesołowska to question where it should be allocated in the subtribe Aelurillina.

Langona sabulosa ia a jumping spider that was first described by the Polish arachnologist Wanda Wesołowska in 2011.

[3][4] The genus was listed in the subtribe Aelurillina in the tribe Aelurillini by Wayne Maddison in 2015.

The black eye field has long brown bristles and is marked by three round spots.

The carapace is similar to the male, although the clypeus has more obvious white hairs and the spinnerets are longer.

[4] The seminal ducts look swollen with large lumpy shapes and lead to complex internal receptacles.

[9] The species resembles the related Langona hirsuta, but may be distinguished by the pattern on the abdomen and the colour of the pedipalps.

However, the design of the epigyne, along with the existence of rod hairs on the eye field and absence of a tuft on the male pedipalp led Wesolowska to query the relationship it has within the subtribe.
