Stenaelurillus siyamae is a species of jumping spider in the genus Stenaelurillus that lives in Sudan. It was first described in 2018 by Dmitri Logunov and Galina Azarkina from a holotype specimen found by a collector named Siyam in the Dinder National Park. The species takes its name from the collector. Only the female has been identified. The spider is small, with a carapace 2 mm (0.079 in) long and an abdomen 2.3 mm (0.091 in) long. The carapace is hairy, brown and has four white streaks, two made of scales on the body and two made of hairs on the edges, while the abdomen is a mixture of grey, brown and yellow with two large brown stripes flanking a thinner white stripe, all made of hairs. It is similar to Stenaelurillus sudanicus also found in the country but can be distinguished by the design of the epigyne, which is oval, its widely separated facing copulatory openings, and long, S-shaped insemination ducts.
Stenaelurillus siyamae was first described by Dmitri Logunov and Galina Azarkina in 2018.[1] It was placed in the genus Stenaelurillus, first raised by Eugène Simon in 1886. [2] The genus name relates to the genus name Aelurillus, which itself derives from the Greek word for cat, with the addition of a Greek stem meaning narrow.[3] It was placed in the subtribe Aelurillina in the tribe Aelurillini in the clade Saltafresia by Wayne Maddison in 2015.[4] Two years later, in 2017, it was grouped with nine other genera of jumping spiders under the name Aelurillines.[5] The species name is taken from the collector of the first example of the spider to be identified, M. Siyam from South Sudan.[6]
