Goleba lyra, is a jumping spider that lives in the dry forest of Madagascar. The spider is medium-sized with a total body that measures between 5.3 and 6.4 mm (0.21 and 0.25 in) in length. As well as being generally larger than the males, the females are paler. The spider is mainly pale yellow with the male having a marking of yellow-brown bands on the back of its carapace, the upper side of its forward section. Its legs are amber. The spider has distinctive copulatory organs that help distinguish the species from others in the genus. The female has long copulatory ducts, longer than others in the genus, that lead to multi-chambered spermathecae, or receptacles. The spider is most easily distinguished from others in the genus by the male's appendage on its palpal tibia, or tibial apophysis. This is curved and contains a set of thin hairs or setae. This combination looks like a harp or lyre. It is this feature that gives the spider its name.
Goleba lyra is a species of jumping spider, a member of the family Salticidae, that was first described by the arachnologists Wayne Maddison and Jiu Xia Zhang in 2006.[1] They assigned it to the genus Goleba, which had been first circumscribed by Fred Wanless in 1980.[2] The genus was a member of the subfamily Lyssomaninae.[3] Molecular analysis demonstrates that the genus is similar to Asemonea and Pandisus. In Maddison's 2015 study of spider phylogenetic classification, the genus was a member of the subfamily Asemoneinae.[2] A year later, in 2016, Jerzy Prószyński placed the genus Goleba in the Asemoneines group of genera.[4]
Wanless described the genus name as "an arbitrary combination of letters".[5] Maddison and Zhang named the species after the shape of the male spider's appendage on its palpal tibia, or tibial apophysis, which is curved and contains a set of thin hairs or setae. This combination looks like a harp or lyre.[6]
