Yllenus Explained

Yllenus is a genus of jumping spiders that was first described by Eugène Louis Simon in 1868.^[1] Until 2019,^[2] 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.^[3]

Y. arenarius is peculiar in building silken nests under the sand surface of sandy dunes it inhabits.^[4]
