The Megapodagrionidae are a family of damselflies, commonly called flatwings for their habit of spreading out the hind wings horizontally when at rest. They belong to the superfamily Lestoidea. The Megapodagrionidae are usually divided into five or six subfamilies: * Argiolestinae * Hypolestinae * Megapodagrioninae * Philosininae * Pseudolestinae (often treated as distinct family) Of these, the Argiolestinae are most diverse, while the Megapodagrioninae and (if placed here) Pseudolestinae are smallish. The others are very small or even monotypic. In addition, two monotypic genera are sometimes placed here as monotypic subfamilies: ''Thaumatoneura'' is otherwise regarded as a monotypic family of the Calopterygoidea. ''Coryphagrion'' was usually also considered a monotypic family in older treatments; in recent times it is often included in the Pseudostigmatidae of the superfamily Coenagrionoidea. ==See also== * List of damselflies of the world (Megapodagrionidae) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Megapodagrionidae」の詳細全文を読む スポンサード リンク
