The body length usually ranges from 65 to 80 mm , and the wing length ranges from 30 to 45 mm . Wings are obviously petiolate and usually outspread at 180° when resting. Wing venation is relatively sparse, with the mf close to arc rather than to nodus . Structures of caudal appendages and genital ligula are simple, with cerci usually longer and more robust than the paraprocts. All species in Megalestes have the same ecological and biological features. They occur in slowly moving montane springs or brooks with dense vegetation. Since the number of studied specimens was large, we placed all of the information concerning “Material examined” into Table 1 .
