Evarcha mirabilis

Evarcha mirabilis is small with looks that are typical for the genus. The male has a carapace that is typically 1.9 mm (0.07 in) long and 1.4 mm (0.06 in) wide. It is rather high high and generally dark brown on top apart from two lighter semicircular areas towards the front. The eye field is similar, with long brown bristles near the eyes, fawn scales around the foremost eyes, while white scale-like hairs cover much of the entire surface. The spider's clypeus, or face, is similarly dark brown. The mouthparts are distinctive with a chelicerae that have a single tooth and a brown labium. The underside, or sternum, is orange. The male spider's abdomen is smaller than its carapace, measuring typically 1.7 mm (0.07 in) in length and having a width of typically 1.1 mm (0.04 in). The topside is russet-brown with a yellow pattern of three thin stripes that cross the body, interrupted by a pattern of a very deep chevron tessellating with the wings of a dove. The underside is dark yellow. The spider has grey spinnerets. The legs yellow to the top and bottom with a central black portion. The copulatory organs have a similar pattern. The pedipalps are likewise yellow and black. The palpal femur is yellow, much of the remainder black. The palpal tibia has a projection with a very broad-base and sharp tip called a tibial apophysis. It has small teeth visible on its sides. …

Evarcha spiders live across the world, although those found in North America may be accidental migrants. The genus is found across Africa. Evarcha mirabilis is endemic to South Africa. The holotype for the species was found in the Ndumo Game Reserve in KwaZulu-Natal in 2005. It has also been found in Western Cape. The first example was discovered in 2017 in Rawsonville. The spider lives on the ground in broadleaf forests. It particularly thrives in fynbos and savanna.
