Plexippus minor

Plexippus minor has a general appearance that is typical of the genus. It is a medium-sized spider. The male has a cephalothorax that measures between 3.1 and 3.3 mm (0.12 and 0.13 in) in length and between 2.3 and 2.5 mm (0.091 and 0.098 in) in width. The carapace is orange with white hairs, is marked with two large brown spots on the back and has a thin black line on the edge. White hairs also adorn the black eye field, which also has red hairs around some of the eyes. The chelicerae are dark brown with white hairs on the top. The abdomen is an oval that is between 3.3 and 3.4 mm (0.13 and 0.13 in) long and 2 mm (0.079 in) wide. It has three stripes on its back, the middle one being white and left and right ones brown. The spinnerets are light with dark tips. The forward legs are also dark, but the rearmost are yellow, although all have dark hairs. The pedipalps are generally more yellow. The bottom part of the cymbium is covered in white hair. The embolus is short, as is the tibial apophysis. The female was first described ten years after the male. Similarly medium-sized, it has a cephalothorax that is typically 38 mm (1.5 in) long and 3 mm (0.12 in) wide. The carapace is brownish-fawn in colour with a very dark, nearly black eye field. Long bron and light bristles can be found around the eyes, and brown and grey hairs at the edges of the body. …

Plexippus minor is endemic to United Arab Emirates. The holotype was collected from Wadi Shawkah in 2007. The species was named for the fact that it is smaller than the other Plexippus species that can be found in United Arab Emirates, Plexippus paykulli.
