Key to Species of Chirostilbia

Several keys exist that purport to separate the females and males of all species of Chirostilbia (e.g., Coscarón, 1987, 1991; Coscarón & Coscarón-Arias, 2007). However, the adults of certain species of this subgenus are very difficult to separate and so the configuration and number of the pupal gill need to be studied in linkreared material for a reliable identification. Therefore, the reader should consult both adult and pupal keys and the morphological descriptions and digital images in this paper when identifying specimens.
