Cybaeopsis is a genus of tangled nest spiders first described by Embrik Strand in 1907,^[3] and transferred from Agelenidae to Amaurobiidae by Pekka T. Lehtinen in 1967.^[4] They all occur in North America except for three species; C. lodovicii, C. theoblicki and C. typica.^[1]^[5]

Members of this genus closely resemble those of the genus Callobius , especially the females.^[5] It is considered a senior synonym of Callioplus,^[2] but not of Alauximus, which is a synonym of Tugana.^[5]

Species

The former C. crassa and C. infumata have both been moved to the Cuban genus, Tugana , and several species have synonyms with the name "Amaurobius", such as C. armipotens and C tibialis.

As of December 2024^[update] this genus contains twelve species:^[1]
