The palpal bulb is also unusually narrow and has a long lobe at the base which can also be used to tell the spider apart from others in the genus.

Langona improcera is a jumping spider that was first described by Wanda Wesołowska and Anthony Russell-Smith in 2000.

[5] It is particularly closely related to the genus Aelurillus, after which the subtribe, tribe and group are named.

The palpal bulb is comparatively narrow with a long lobe at the base and a bump in the femur.

[7] It differs from Langona warchalowskii in the narrowness of the palpal bulb and the size of the lobe at its base.

[1] The holotype was discovered in the 1997 in the Mkomazi National Park, living in shrub dominated by Senegalia mellifera.
