English abstract
Two research expeditions surveyed Odonata communities within Wadi Sayq, a coastal wadi system 20 km in length, situated in the southwest Jabal Qamar mountain range, Dhofar Province of Oman. Sample collection was undertaken from 2 to 29 February 2012, and from 6 February to 7 March 2013. Eight hundred and ninety seven individuals were recorded belonging to 20 species and Tholymis tillarga (Fabricius, 1798) is new for the Arabian Peninsula. A single record of Rhyothemis semihyalina (Desjardins, 1832) increases significantly the known distribution range of this species in Arabia to the West. Reasons for the observed temporal and spatial variation in community composition are explored and notes on species habitat preferences are included.
