FIGURE 6 in Checklist of the dragonflies (Odonata) of Iran with new records and notes on distribution and taxonomy

FIGURE 6. Male appendices of the three Sympecma species: The position of the basal tooth on the appendix superior in comparison to the length of the appendix inferior is different. In S. gobica (mountain brook, Khorãsãn-e-Shomali) the basal tooth is located just on the end of the appendix inferior (A), in S. paedisca (Atrak River, Khorãsãn-e-Shomali) the appendix inferior ends before the basal tooth of the appendix superior (B), and in S. fusca (mountain brook, Azarbãyejãn-e-Garbi) the appendix inferior ends distal from the tooth of the appendix superior (C), (t—tooth, a—appendix inferior).
