Female sperm storage organs ( a − d , dorsal view) and male genitalia ( e − f , ventral view) of Calopteryx cornelia . The intact sperm mass (darken part) is included in the bursa copulatrix (bc) and entire spermatheca (sp) ( a ), in the entire spermatheca ( b ), in the right spermathecal tube ( c ), and only in the apical part of the right spermathecal tube ( d ). The male aedeagus consists of the recurved head (rh) and the left and right lateral processes (lp) of immature ( e ) and mature ( f ) males. The angle (θ) and outward distance ( d ) of each lateral process were measured. Scale bar is 1 mm.
