A New Predacious Species of Cosmolaelaps (Mesostigmata: Laelapidae) from Rose Greenhouses in The Netherlands with Extensive Morphological Analyses and Ontogeny

A new species from the genus Cosmolaelaps, with potential to control western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), were collected litter and remains of plant material on soil different rose greenhouses in The Netherlands. Collected specimens used initiate a laboratory colony. Subsequently, sample mites developmental stages analysed morphologically, by means measurement structures determination main morphological characteristics chaetotaxy leg segments. species, Cosmolaelaps sabelisi sp. nov., is described illustrated based characters adult immature (including protonymph deutonymphal stages) compared closely related species.
