Xylesthia
Xylesthia is a genus of wall spiders in the family Oecobiidae, a group of small arachnids known for constructing flat, tangled webs on vertical surfaces such as walls, rocks, and tree trunks. These spiders are characterized by their compact bodies, relatively long legs, and distinctive spinneret arrangement. The genus is poorly documented in North American faunal surveys, with most species described from other regions. The 'n-sp' designation indicates an undescribed or unidentified species within the genus.
