The female is significantly larger than the male, particularly in the abdomen, which is also wider and a lighter brown.

It has the toothless chelicerae typical of the genus, and a single appendage, or apophysis, on the palpal tibia.

Langona hirsuta is a jumping spider that was first described by Wanda Wesołowska and Charles Haddad in 2011.

[5] Haddad and Wesołowska saw the position of the species in Aelurillina as uncertain as it has many features that were not found in other spiders, even genera other than Langona.

The pedipalp tibia has a single apophysis, or appendage and the palpal bulb has a triangular lobe at the rear.

[8] The carapace is shaped like a pear, high and covered with dense white hairs.

In some specimens there is a pattern of three light spots surrounding an irregular streak across the middle of the abdomen.

The seminal ducts are wide and coiled, which lead to large receptacles that are many-chambered.

[11] The different Langona species generally cannot be distinguished from each other or from other members of the group by either their colours or the patterns that appear on their bodies, but by the structure of the copulatory organs.

[1][14] The holotype was found in the nature reserve near Erfenis Dam, Free State, in 2009.

Other examples have been identified in Free State National Botanical Garden, the area around Krugersdrift Dam, Sandveld Nature Reserve, as well as farms near to Brandfort Boshof, Bothaville and Kimberley.
