This species belongs to the barkeri species group of the genus Neoseiulus , as the spermathecal atrium is large and forked at junction with the major duct. It belongs to the barkeri species subgroup as the calyx is not markedly constricted at junction with the atrium, the atrium is deeply forked at the junction with the major duct without vacuolated area, and the major duct, atrium and calyx are of approximately the same width ( Chant and McMurtry 2003a ). Neoseiulus barkeri has a worldwide distribution (see below and Moraes et al. 2004a; Demite et al. 2020 ). It is a well-known predator of T . urticae and also of thrips, and is released in greenhouses (strawberry, cucumber, eggplant) to control them. Various studies have shown its ability to control Frankliniella occidentalis (Pergande) ( Rodriguez-Reina et al. 1992 ) , Thrips tabaci Lindeman ( Broodsgaard and Hansen 1992 ) and T. urticae in cucumber ( Fan and Petitt 1994b ). Fan and Petitt (1994a) showed that augmentative releases of N. barkeri provided control of Polyphagotarsonemus latus (Banks) on peppers. N. barkeri constitutes a potential BCA in several crops especially vegetable greenhouses. This is the first report of that species from Slovenia .

( Cucurbitaceae ), 20/VI/2018 . Remarks : The description and measurements of the adult females collected agree with those provided by Ferragut et al. (2010) for specimens from Spain and by Kreiter et al. (2020) for specimens from La Réunion and various regions of the world.
