Yllenus

Yllenus is a genus of jumping spiders that was first described by Eugène Louis Simon in 1868.^[2] Until 2019,^[3] it was considered a senior synonym of Pseudomogrus, and many of the species formerly placed here were transferred to new genera Logunyllus and Marusyllus by Jerzy Prószyński in 2016.^[4]

Y. arenarius is peculiar in building silken nests under the sand surface of sandy dunes it inhabits.^[5]
