Stenaelurillus senegalensis
Species of spider
Stenaelurillus senegalensis is a species of jumping spider in the genus Stenaelurillus that lives in Senegal. Named after the country where it was first found, it was first described in 2018 by Dmitri Logunov and Galina Azarkina. The spider is small, with a carapace between 1.7 and 2.5 mm (0.067 and 0.098 in) long and abdomen between 1.6 and 3.45 mm (0.063 and 0.136 in) long, although the female is larger than the male. The carapace is hairy, brown and has two white stripes. The abdomen differs between the male and female. The male has a pattern of yellow spots and a brown stripe. The female has a cross of yellow stripe and two brown stripes. The male has a bulging palpal bulb while the female has a flat epigyne with widely separated and backward-facing copulatory openings. It is similar to Stenaelurillus nigricaudus, also found in the country, but can be distinguished by the design of its long straight embolus and the lack of pockets in the epigyne.
