Stenaelurillus furcatus is a species of jumping spider in the genus Stenaelurillus that lives in Namibia. It was first described in 2014 by Wanda Wesołowska. The spider is small, with a brown cephalothorax between 2.2 and 2.9 mm (0.087 and 0.114 in) in length and a black abdomen between 2.0 and 3.6 mm (0.079 and 0.142 in) long. The carapace is brown and covered in scales, while the abdomen is a black oval. The chelicerae are yellow to light brown. It can be distinguished from other members of the genus by the short forked appendage on the male's palpal bulb, after which the spider gets its name. The female has a distinctive arrangement of a deep pocket and separated copulatory openings in the epigyne.
