The spider is generally brown, apart from small features like the white hairs that can be seen on its face, or clypeus, and its greyish spinnerets.

The carapace, the topside of the cephalothorax, is darker than the sternum, or underside and, unusually for the genus, a scutum covers the top of the abdomen.

Euophrys maseruensis is a species of jumping spider that was first described by Wanda Wesołowska, Galina Azarkina and Anthony Russell-Smith in 2014.

[2] It was one of over 500 species identified by the Polish arachnologist Wesołowska during her career, more than any other contemporary writer and second only to the French archnologist Eugène Simon.

[5] In Wayne Maddison's 2015 study of spider phylogenetic classification, the genus Euophrys was listed to the tribe Euophryini.

[12] Euophrys maseruensis is a very small spider with a body divided into two main parts: a broad cephalothorax and an oval abdomen.

[1] The palpal bulb is brown and bulbous, with a bulge to its base and a thin embolus that loops around as it emanates from its top.

[14][15] The narrow tibial apophysis and large embolic disk are key to distinguishing the spider from related species like Euophrys recta.
