Note. See Copley et al. (2009) for genus diagnosis and descriptive details as well as a key to the species groups (females only) of the Holarctic and Californian clades of Cybaeus . See Bennett et al. (2016) for a revision of the Nearctic species of the Holarctic clade of Cybaeus . Bennett (2005, 2017) provided keys to all Nearctic cybaeid genera. Males of Cybaeus species often are difficult to assign to particular species groups (see the Introduction in this paper for discussion of the nature of species groups of Cybaeus ). When in doubt about the group affiliation of male specimens, explore the keys to the Holarctic clade species in the tetricus and angustiarum groups ( Bennett et al. 2016) or consider one of the five other Californian clade species groups ( aspenicolens , consocius , devius , septatus , and tardatus ) discussed by Bennett (1991) and Copley et. al (2009).
