Massagris maculosa

Massagris maculosa is a species of jumping spider in the genus Massagris that ilves in South Africa. The spider is small, with a cephalothorax between 1.7 and 1.8 mm (0.067 and 0.071 in) long and an abdomen between 1.5 mm (0.059 in) and 1.7 mm long. It is generally creamy with a distinctive pattern of dark dots and spots on the abdomen. The male carapace is brown and sternum is yellow and brown. The female's legs are whitish and the male's brownish. It has a silvery eye field formed of translucent guanine crystals marked with darker patches. The male has a single very long, pointed and slightly curved projection on the palpal tibia known as a tibial apophysis. There are distinctive hoods on the female's epigyne that help distinguish the species from others in the genus. The spider was first described in 2018 by the arachnologists Wanda Wesołowska and Charles Haddad.

The male cephalothorax is typicailly 1.8 mm (0.071 in) long and 1.3 mm (0.051 in) wide. The carapace, the hard upper part of the cephalothorax, is pear-shaped and moderately high. It is brown with white hairs on its slopes. It has a silvery eye field formed of translucent guanine crystals marked with two rounded black spots in the middle. There are long brown bristles around the eyes themselves. The eyes are mounted on well-developed tubercles. The underside of the cephalothorax, or sternum, is yellow in the middle and brown to the sides. The spider has a low brown clypeus that has a scattering of white hairs on it. Its chelicerae are similar to Massagris mohale, with five small teeth towards the front and a large plate-shaped tooth to the rear. The remainder of the mouthparts, the labium and maxillae are brownish with light tips. The male spider's abdomen is typically 1.7 mm (0.067 in) long and 1.3 mm wide. It is a creamy-white ovoid, marked with pattern composed of dark dots and spots on both the top and bottom.
