Evarcha russellsmithi

Evarcha russellsmithi is a small to medium-sized with looks that are typical for the genus. The spider's body is divided into two main parts: a larger, almost rectangular cephalothorax and a smaller, rounded, almost pod-like abdomen. The male has a cephalothorax that is typically 2.2 mm (0.09 in) long and 1.7 mm (0.07 in) wide. The carapace, the hard upper part of the cephalothorax, is high and generally yellow. There are translucent and white hairs on the eye field and long dark bristles and black rings around the eyes themselves. The slopes of the carapace are brown and have grey and brown hairs. The underside, or sternum, is yellowish with a covering of short dark hairs in the middle. The spider's face, or clypeus, is brownish and has a scattering of white hairs on its cheeks. Externally, the spider's mouthparts, are distinctive. It has brownish chelicerae and yellowish labium, although the latter has lighter tips. The spider's abdomen is smaller than the carapace, measuring typically 1.8 mm (0.07 in) in length and 1.3 mm (0.05 in) in width. The top is covered in brownish and whiteish hairs, amongst which are a scattering of long brown bristles. It is brown with a wide yellow stripe across the front. The remaining surface has a pattern of indistinct spots in the middle and stripes to the rear. …

Evarcha spiders live across the world, although those found in North America may be accidental migrants. Although the genus is found across Africa, Evarcha rotundibulbis is endemic to Ethiopia. The holotype was found 60 km (37 mi) east of Nazret, East Shewa Zone, in 1986 at an altitude of 1,400 m (4,600 ft) above sea level. The spider lives amongst Acacia–Commiphora bushlands and thickets amongst woodland dominated by Acacia and Commiphora species.
