Evarcha arabica

Evarcha arabica is a small, light-coloured spider with looks that are typical for the genus. The spider's body is divided into two main parts: a cephalothorax and an abdomen. The male has a carapace, the hard upper part of the cephalothorax, that is between 21 and 2.5 mm (0.83 and 0.10 in) long and 1.7 and 1.9 mm (0.07 and 0.07 in) wide. It is rather high, dark with a brownish-orange area towards the front and darker sides. There is a scattering of whit hairs visible. It has a nearly-black eye field with small reddish-orange scales around the eyes themselves. Tiny brown and orange hairs cover the eye field. The underside of the cephalothorax, or sternum, is dark yellow. The spider's face, or clypeus, is low and brown. Its mouthparts are distinctive. The chelicerae and labium are brown, which contrasts with the lighter brown maxillae with their pale yellow inner sides. The male spider's abdomen is an oval that is narrower than the carapace. It measures between 1.8 and 2.5 mm (0.07 and 0.10 in) in length and having a width of between 1.2 and 1.6 mm (0.05 and 0.06 in). The top is generally blackish-brown with a pattern that consists of a large, wide and yellowish-orange belt in the middle, irregular in shape, and either one or two pairs of white spots towards the sides to the rear. It is hairless apart from a scattering of long brown hairs. …

Evarcha spiders live across the world, although those found in North America may be accidental migrants. Evarcha arabica is endemic to Yemen. The holotype was discovered in 2001 near Hammam 'Ali. Other examples were found locally.
