Goleba pallens is a species of jumping spiders that is endemic to the Seychelles. A member of the genus Goleba, Goleba pallens is a medium-sized spider that measures between 4.4 and 4.76 mm (0.173 and 0.187 in) in total length. It is generally whitish-yellow with a pale amber thorax. The male has an indistinct pattern of reddish-brown bands but otherwise the spider is generally patternless. The female's legs are simple and pale yellow while, in contrast, the male has legs that fade from light yellow to pale amber and have dark amber stripes on the front two pairs. They have many strong leg spines. The female's copulatory organs are distinctive, particularly its copulatory openings near the rear of its epigyne, the visible external part of its copulatory organs. The male has an embolus that is accompanied along much of its length by another appendage that shows clear signs of sclerotization. The spider was first described 1877. Initially placed in the genus Lyssomanes, the genus was moved to Asamonea by Eugène Simon in 1885 and was then to Goleba in 1980 by Fred Wanless.
Goleba pallens is a species of jumping spider, a member of the family Salticidae, that was first described by the arachnologist John Blackwall in 1877.[1] He allocated it to the genus Lyssomanes, which had been first circumscribed by Nicholas Marcellus Hentz in 1845.[2][3] In 1885, Eugène Simon moved the species to Asemonea, first circumscribed by Octavius Pickard-Cambridge in 1869, with the name Asemonea pallens.[4]
When Fred Wanless circumscribed Goleba in 1980, he transferred the species to the new genus. Wanless described the generic name as "an arbitrary combination of letters".[2] He allocated the species to the group pallens, which are distinguished by their copulatory organs.[4] Molecular analysis demonstrates that the genus is similar to Asemonea and Pandisus.[5] In Wayne Maddison's 2015 study of spider phylogenetic classification, the genus was a member of the subfamily Asemoneinae.[5] A year later, in 2016, Jerzy Prószyński placed it in the Asemoneines group of genera,[6]
