Ragatinus maddisoni

Ragatinus maddisoni is the type species for the genus Ragatinus. It is a species of jumping spider that is endemic in Kenya, living in forested afromontane regions. First described in 2016 by Angelika Dawidowicz and Wanda Wesołowska, it is named after the arachnologist Wayne Maddison. The spider is medium-sized and generally light brown, with a cephalothorax that is between 2.0 and 3.0 mm (0.079 and 0.118 in) long and an abdomen between 2.2 and 4.0 mm (0.087 and 0.157 in) long. It has light brown legs, the foremost ones being longer and darker. The species is most easily distinguished from other spiders by its copulatory organs. The female has a triangular depression in the middle of its epigyne and the male has a protuberance with teeth attached to the base of its curved embolus.
