Stenaelurillus nigricaudus

It is a jumping spider that lives in Algeria, Burkina Faso, Gambia, Mali, Niger and Senegal.

The male was first described by Eugène Simon in 1886 and the female initially in 1936 by Ludovico di Caporiacco and more thoroughly by Nikolaj Scharff and Tamás Szűts in 2005.

In 2015, the genus was placed in the subtribe Aelurillina in the tribe Aelurillini in the clade Saltafresia by Wayne Maddison.

[7] In 2018, Aelurillus sahariensis, first described by Lucien Berland and Jacques Millot in 1941, was also identified as a synonym of the species by Dmitri Logunov and Galina Azarkina.

The clypeus is light brown or yellow and the chelicerae is dark brown-yellow with two very small teeth at the front.

The ovoid abdomen has similar colouring and has a single darker stripe down the middle.

However, even they doubted that the examples they had were from the species so was not until Wanda Wesołowska's article of 2014 that a full description was made.

[13] It has a more detailed pattern of wide stripes, covered in scales, and yellow spots.

The epigyne is small with a flat plate, a concave rear and a deep narrow pocket.

The first example of the species from Algeria, originally named Stenaelurillus nigritarsis, was identified in Bou Saâda at the same time.

[15][16] Subsequently, the spider was identified from specimen found in other areas of Senegal, including Richard Toll.

[17] The species was subsequently discovered, based on a male specimen found in 2001, to live in the Kiang West National Park in the Gambia.
