Figure 3. SEM images of maxillulae of Anonyx nugax (a–d) and Tmetonyx cicada (e–h). (a) Head with maxillulae in situ shown in ventral view (with maxillae and maxillipeds removed). (b) Right maxilla in oral view. (c) Apical setation on the outer plate of the left maxilla in aboral view. (d) Setation on the inner plate and the base of the outer plate of the left maxilla in aboral view. (e) Head with maxillulae in situ shown in ventral view (with maxillae and maxillipeds removed). (f) Inner plate and the base of the outer plate of the right maxillula in aboral view. (g) Apical ends of maxillular palps in situ in ventral view. (h) Apical setation on the outer plate of the right maxillula in aboral view. Abbreviations: bo – setal band on outer plate of maxillula; lb – labrum; ml ip – maxillular inner plate; ml op – maxillular outer plate; ml pl – maxillular palp; pi – pappose seta on inner plate of maxillula; smp – spine-like setae of mandibular palps; st1–6 – spine teeth in apical row on maxillular outer plate; stA-D – spine teeth in subapical row on maxillular outer plate. Scale bars: A, B: 1 mm; C, E: 500 µm; D, F, H: 200 µm; G: 100 µm.
