Hyllus ramadanii is a species of jumping spider in the genus Hyllus that is endemic to Tanzania. It lives in rocky environments. The spider was first described in 2000 by Wanda Wesołowska and Anthony Russell-Smith. The spider is medium-sized, with a brown carapace between 3.1 and 3.2 mm (0.12 and 0.13 in) long and an abdomen 3.2 and 5.0 mm (0.13 and 0.20 in) long. The female is larger than the male. It can be differentiated from other species in the genus by its coloration and copulatory organs. The male has a pattern of three white patches on its carapace and a horseshoe shape on its abdomen. The female has three irregular orange streaks on its carapace and a yellow pattern that looks like a tree on its abdomen.
Hyllus ramadanii is a jumping spider that was first described by Wanda Wesołowska and Anthony Russell-Smith in 2000.[1] It is one of over 500 species identified by the Polish arachnologist Wesołowska.[2] The species is named in honour of the Tanzanian zoologist Ramadani Makusi.[3] It was allocated to the genus Hyllus, first circumscribed by Carl Ludwig Koch in 1846, on the basis of its coloration, although Wesołowska and Russell-Smith noted that there is a wide diversity amongst Hyllus species and their diagnosis was not conclusive.[4] The genus is similar to Evarcha, differing in size.[5] Molecular analysis confirms that they are related but the precise relationship between the genera is unknown and species from one genus are sometimes misidentified as members of the other.[6][7] The genus is found throughout Africa and contains one of the largest jumping spiders discovered.[8]
In Wayne Maddison's 2015 study of spider phylogenetic classification, the genus Hyllus was placed in the clade Saltafresia.[9] He considered that it a member of the subtribe Plexippina in the tribe Plexippini.[10] Two years later, in 2017, Jerzy Prószyński grouped the genus with nine other genera of jumping spiders under the name Hyllines, which was named after the genus. He used the shape of the embolus as a distinguishing sign for the group.[11] Hyllines was itself tentatively placed within a supergroup named Hylloida, again named after the genus.[12]
