臺灣蜻蜓的分類研究已超過百年,因為許多國內外學者的努力,詳細記錄了有關本土蜻蜓物種的發現,所以臺灣蜻蜓的新紀錄種及新種大多在西元2000年之前就已被報導,但隨著投入蜻蜓研究及觀察的人越來越多,最近十年內仍然有少數新種被發現,而且都是臺灣的特有種,例如隱身在北部淺山小溪的鉤鋏晏蜓、只出現在坪林山區溪流的朱環鼓蟌,還有棲息在東部人跡罕至山區沼澤地的短鋏晏蜓。
Dragonflies in Taiwan have been studied for more than a century. While many new species or newly recorded species were already known before 2000, we are still seeing new species being discovered now as more dragonfly watchers join the rank. All of the recently discovered species are endemic to Taiwan, such as the Hook-tailed Bog-hawker (Sarasaeschna chiangchinlii), Orange-bellied Jewel (Rhinocypha taiwana), and Short-tailed Bog-hawker (Sarasaeschna kaoi).
