Modified seta of segment 13 of A1R short, not reaching beyond tip of spinous process on segment 14; spinous process of segment 14 well developed (Fig. 16A, C, E); spinous process of segment 15 of A1R shorter than spinous process of segment 14 (Fig. 15F); segment 20 of A1R typically with falciform process; falciform process variable, when present can attain length up to half length of segment (Fig. 16B, D, F).
