Taxonomy

Thiratoscirtus elgonensis is a species of jumping spider that was first described by Angelika Dawidowicz and Wanda Wesołowska in 2016.[1] One of over 500 different species identified by Wesołowska in her career, it is named for the Mount Elgon, where t was first found.[2][3] They allocated the spider to the genus Thiratoscirtus, first circumscribed in 1909 by Eugène Simon. The genus is very diverse and contains many monophyletic groups.[4]

Thiratoscirtus is a member of the subtribe Thiratoscirtina in the tribe Aelurillini.[5] The genus is closely related to Nimbarus.[6] In 2016, Mellissa Bodner and Wayne Maddison proposed a subfamily Thiratoscirtinae for the genus and its related genera.[7] This overlapped with a group of genera named Thiratoscirtines after the genus, created by Jerzy Prószyński in 2017.[8] Phylogenetic analysis has shown that the genus is related to the genera Alfenus, Bacelarella, Longarenus and Malloneta.[9] It is likely to have diverged between 16.3 and 18.7 million years ago.[10] Maddison allocated the tribe to the subclade Simonida in the clade Saltafresia in the clade Salticoida.[11]

Description

Thiratoscirtus elgonensis is a medium-sized spider. The spider's body is divided into two main parts:a cephalothorax and an abdomen.[12] The male has a cephalothorax that measures typically between 2.0 and 2.5 mm (0.08 and 0.10 in) in length and 1.6 and 1.9 mm (0.06 and 0.07 in) in width. The carapace, the hard upper part of the cephalothorax, is a moderately high oval that is generally brown and covered in brown hair. It is marked with a light band across the middle and white streaks formed by hairs on the sides. There is a furrow-like depression in the centre of carapace. A black field surrounds the eyes that is covered in black hairs, with a few longer brown bristles visible particularly around the forward eyes. The sternum, the underside of the cephalothorax, is brown. Its face, or clypeus, is low and light brown with light hairs.
