1. Occiput, mesopleuron, mesosternum and propodeum ocheous yellow ( Figs 1 View FIGURE 1 A, C, 2B); metasomal tergites 3 and 4 at least with posteriorly and laterally whitish or ochreous yellow ( Figs 2 View FIGURE 2 B, 3C); dark mark (brown or black) on middle part of mesoscutum absent, or if present, only on anterior half ( Figs 4 View FIGURE 4 A, 5C, E).....................................................2
-. Occiput, much of mesopleuron and mesosternum, propodeum and metasomal tergites 3 and 4 (except anterolateral areas) black ( Fig. 9); dark (black) mark on middle part of mesoscutum extending to scutellar sulcus........... T. tridentata (Enderlein)
2. Metasomal tergites 2–5 broadly dark brown or black medially surrounded by paler marks ( Figs 3 View FIGURE 3 A, 8C) [only males known]......................................................................................................3
