A checklist of 19 Odonata species observed between 30.vi. and 04.vii.2019 on the hitherto odonatologically unexplored island Pulau Perhentian Besar, Terengganu State, Malaysia, is given. Most notable is the record of the recently described Leptogomphus tioman Choong, 2016, for which the currently known distribution is extended and the variability in coloration details based on photographs of adult males is briefly discussed. Orthetrum pruinosum schneideri Förster, 1903, is new to Terengganu, bringing the total recorded odonates from the state to 133 species.
