Evarcha awashi
Evarcha awashi is a species of jumping spider in the genus Evarcha that lives in Ethiopia. The species was first described in 2008 by Wanda Wesołowska and Beata Tomasiewicz. The spider is small, with a cephalothorax measuring between 2.0 and 2.3 mm (0.08 and 0.09 in) long and an abdomen between 1.9 and 2.4 mm (0.07 and 0.09 in) long. The male and female are similar in size but differ slightly externally. The male carapace is orange while the female is brown, both with a darker eye field. The pattern on the abdomen is generally similar, a combination of light background and dark patches, but the female has less contrast between the two. The legs are mainly brown with yellowish tarsi. Its copulatory organs are distinctive. The male has a short embolus that follows the palpal bulb and a sharp tooth on its short wide and blunt protrusion on its palpal tibia, or tibial apophysis. The female has insemination ducts that narrow into multi-chambered spermathecae.

Description
Evarcha awashi is a small spider. The spider's body is divided into two main parts: a rather rounded almost rectangular cephalothorax and more rounded and oval abdomen that is narrower to the rear. The male has a cephalothorax that is between 2.1 and 2.3 mm (0.08 and 0.09 in) long and 1.7 and 1.8 mm (0.07 and 0.07 in) wide. The spider's abdomen is between 1.9 and 2.3 mm (0.07 and 0.09 in) long and 1.4 and 1.6 mm (0.06 and 0.06 in) wide. The carapace, the hard upper part of the cephalothorax, is high, mainly orange with brownish sides that have a covering of white hairs and a dark line along the sides. The eye field is also darker and the eyes are surrounded by white and orange scales and tufts of white hair. The underside, or sternum, is yellowish with long white and greyish hairs. The spider's face, or clypeus, is also high and has a dense covering of bright orange hairs. The mouthparts are brown, apart from the chelicerae, which are dark brown. It has a single tooth. The spider's abdomen is greyish brown with a pattern of pale spots that look like a series of four interrupted stripes on top and a heart-shaped patch to the rear. There is a small delicate orange scutum visible towards the front of the abdomen. Thin brown hairs adorn the surface, interrupted by a scattering of long brown bristles. …
Range & habitat
Evarcha spiders live across the world, although those found in North America may be accidental migrants. Although the genus is found across Africa, Evarcha awashi is endemic to Ethiopia. The holotype was found in the Awash National Park in 1987 in what was then Hararghe. Other examples were also found locally. It thrives in stony grassland. Examples have been found in areas of human habitation, including mounds of cut grass. It also lives near to rivers in woodland of Vachellia nilotica trees and under stones amongst shrubs of the genus Commiphora.
