FIGURE 7. Phenotypic variation of six adult male Phanoperla constanspina sp. nov. based on the shape and structure of hemitergites (HT) and unbranched anterior process (AP), adorned with variable short setae on tergum 9. (A) (Haplotype: A- G23.m) Medium-sized AP, body and slightly bent on the pointed apex, setal patches isolated from each other. (B) (Haplotype: A-H7.m) AP small and pointed, setae located above the apical tip adjacent to each other. (C) (Haplotype: A-H16.m) Plump base and small AP (Fig. 5), with slightly pointed tip, paired setal patches adjacent and overlapping. (D) (Haplotype: A-H12.m) Medium and longer AP, bent on the inner side near the apex, setal patches fused, distributed along and near the process. (E) (Haplotype: A-E23.m) AP blunt on the tip in a medium-sized body, setal patches adjacent. (F) (Haplotype: A-H11.m) HT and AP broad and plump, resembling a hook-like structure at the tip, setal patches adjacent.
