Taxonomy

Euophrys miranda is a species of jumping spider that was first described by Wanda Wesołowska Galina Azarkina and Anthony Russell-Smith in 2014.[1] They allocated it to the genus Euophrys, which had been first circumscribed by Carl Ludwig Koch in 1934.[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.[3] The genus is named for a Greek word that can be translated "fair eyebrows".[4] The species is named for a Latin word that can be translated "curious".[5]

In Wayne Maddison's 2015 study of spider phylogenetic classification, the genus Euophrys was listed to the tribe Euophryini.[6] First circumscribed by Simon in 1901, the tribe has also been known as Euophrydinae, but the original name is now more prevalent.[7] It is a member of a subgroup of genera called Evophrydeae after the latter name.[8] It is a member of the the clade Saltafresia.[9] Analysis of protein-coding genes showed it was particularly related to Thorelliola.[10] In 2016, Prószyński added the genus to a group of genera named Euopherines, named after the genus.[11] This is a member of the supergroup of genera Euphryoida.[12]

Description

Euophrys miranda is a very small spider with a body divided into two main parts: a broad oval cephalothorax and a more rounded oval abdomen.[13] It has a cephalothorax that is typically 1.6 mm (0.06 in) long and 1.2 mm (0.05 in) in width, compared to the abdomen, which is typically 1.9 mm (0.07 in) in length and 1.4 mm (0.06 in) wide.The carapace, the hard upper part of the cephalothorax, is dark brown with slight mottling and a covering of thin translucent hairs on its surface. The eye field is very dark, nearly black. The underside of the cephalothorax, or sternum, is brown. The spider's face, or clypeus, is low and also dark. Its mouthparts, including its chelicerae, labium and maxillae, are also brown. It has two teeth at the front of its mouth and a single tooth to the rear.[5]

The spider's abdomen is larger and less shiny than its carapace. The top has an unusual pattern of wavy lines made of alternative light and dark chevrons on a dark background. The underside is dark and marked with four pale lines that run from the front to the back formed of light dots. The spider has dark grey spinnerets. Its legs are generally light brown, although with a grey hint, with dark hairs and spines. The pedipalps are brown.[5]

The spider has distinctive copulatory organs.
