Cybaeopsis is a genus of tangled nest spiders first described by Embrik Strand in 1907, and transferred from Agelenidae to Amaurobiidae by Pekka T. Lehtinen in 1967. They all occur in North America except for three species; C. lodovicii, C. theoblicki and C. typica.
Members of this genus closely resemble those of the genus Callobius, especially the females. It is considered a senior synonym of Callioplus, but not of Alauximus, which is a synonym of Tugana.
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.
this genus contains twelve species: Cybaeopsis armipotens (Bishop & Crosby, 1926) – USA Cybaeopsis euopla (Bishop & Crosby, 1935) – USA, Canada Cybaeopsis hoplites (Bishop & Crosby, 1926) – USA Cybaeopsis hoplomachus (Bishop & Crosby, 1926) – USA Cybaeopsis lodovicii Ballarin & Pantini, 2022 – Italy Cybaeopsis macaria (Chamberlin, 1947) – USA Cybaeopsis pantopla (Bishop & Crosby, 1935) – USA Cybaeopsis spenceri (Leech, 1972) – USA Cybaeopsis theoblicki (Bosmans, 2021) – Portugal Cybaeopsis tibialis (Emerton, 1888) – USA, Canada Cybaeopsis typica Strand, 1907 – Russia (Sakhalin, Kurile Is.), Japan Cybaeopsis wabritaska (Leech, 1972) – USA, Canada
