As the colouring is similar to other spiders in the genus, the species is best distinguished by its copulatory organs.
The male has an unusually small embolus that has its base hidden in the palpal bulb cymbium.
The female has a unique epigyne with a shallow depression lined with sclerotised wings covering the gonopores and a simple internal morphology.
Langona lotzi is a jumping spider that was first described by Wanda Wesołowska and Charles Haddad in 2011.
The pedipalps are brownish on top and black underneath, with white hairs on the cymbium and tibia.
The epigyne has a shallow depression, which has highly sclerotised wing-like edges that cover the gonopores.
[8] Like other Lagona spiders, there is a single appendage on the pedipalp tibia, which enables it to be distinguished from other Aelurillinae.
[9] 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] It was initially only been found in the Eastern part of the Free State, South Africa.
