FIGURE 6. a. Control region of Styloperla spinicercia mitogenome. TR1 and TR2 are the abbreviation of tandem repeat units. The colored panes indicate the structural elements in control region, leading sequences are shown as a blue pane, strings of TR1 as orange panes, A+T-rich sequences as red panes, strings of TR2 as purple panes and the end of control regions as a green pane. b. Lateral view of terminalia of S. spinicercia, arrow showing the diagnostic apex of the spur.
