- Mid and hind femora lacking posterodorsal bristles; face with bright blue pruinescence............... T. grandis View in CoL sp. nov.

4 Pterostigma present, although sometimes faint ( Fig. 16 View FIGURE 16 G); face with bright blue pruinescence; male fore femur with 4–6 basal anteroventral setae, some nearly subequal to width of femur ( Figs 17 View FIGURE 17 M, N); female abdominal sternum 7 with strong posterior marginal setae rather evenly arranged ( Fig. 15 View FIGURE 15 B)........................................... T. stigmatica View in CoL sp. nov.
