Contribution to the subfamily Panchaetothripinae (Thysanoptera, Thripidae) from Saudi Arabia, with two new genera records and an illustrated key

We present the first illustrated key to the Panchaetothripinae genera of the Arabian Peninsula and a checklist of Arabian species to facilitate their recognition. Moreover, two genera and species, <i>Hercinothrips femoralis</i> (Reuter) and <i>Rhipiphorothrips cruentatus</i> Hood, are recorded as new to Saudi Arabia. New distributional data for each species is also given. The presence of greenhouse thrips <i>Heliothrips haemorrhoidalis</i> Bouche in the country is doubtful. The species has not been recovered despite extensive surveys across the country spanning over six years. However, it is kept in the Arabian species list until further confirmations.
