The species was first described in 2014 by Wanda Wesołowska, Galina Azarkina and Anthony Russell-Smith.

The female has wide insemination ducts that loop in the middle and spherical spermathecae.

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

[2] The classification is uncertain, as the female has very different copulatory ducts to other species in the genus.

[3] 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] The species is named for a Latin word that can be translated "delicate"and reflects the small size of the spider's body.

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

The carapace, the hard upper part of the cephalothorax, is a moderately high oval.

The carapace is similar to the male but the abdomen is creamy-white on top with a pattern of dark spots fused into bands that cross its surface.

The palpal tibia has a relatively long and thin projection, or tibial apophysis.

[15][16] The male's palpal bulb is similar to the related Euophrys nana, but the embolus is shorter.

[17] Like many African species of Euophrys spider, it lives in lowland forests.
