Scolothrips longicornis Priesner, 1926 (Thysanoptera: Thripidae: Thripinae) is a predaceous thrips species originating from Western‐Palearctic zoo‐ geographical region. It is a predator of all stages of spider mites from the family Tetranychidae. S. longicornis has been recorded in many European countries: Poland, Czech Republic, Slovakia, Hungary, Romania, Austria, France, Spain, Italy, United Kingdom and Finland. In Europe, findings of six species from the genus Scolothrips Hinds, 1902, have been recorded, S. longicornis including. S. longicornis was found for the first time in Croatia in 2017 on leaves of soybean and ornamental plants Hydrangea sp. and Datura sp. in greenhouses. In 2018, the species was also recorded on indoor Alocasia sp. Predatory thrips species was present on leaves of plants in association with polyphagous spider mite Tetranychus urticae Koch, 1889. Thrips and spider mites present in collected samples were identified to the species level on the basis of microscopic morphological characters, using classical identification method according to relevant morphological keys. Since, S. longicornis is a new thrips species for the fauna of Croatia and one of the numerous newly discovered, the last published national check list of thrips fauna should be updated.
