FIGURE 3. Theratta mannavan n. sp., SEM. A, D, E: M paratype (ZFMK-MYR 9483A). B, C, F, G: M holotype (ZFMKMYR9482B1). H: M paratype (ZFMK-MYR 9482B2). A: Head, frontal view. B: Antenna. C: Sensilla basiconica on antennomeres 5 and 6. D: Apical disc with four sensory cones. E: Mouth parts, dorsal view. F: Mouth parts, ventral view. G: Anterior body, lateral view. H: Tergites, lateral view. Abbreviations: ac = apical cone; ag = anterior gonopod; an = antenna; br = body ring; co = collum; gn = gnathochilarium; le = leg; lb = labrum; ms = macrosetae; mz = metazonite; om = ommatidia; oz = ozopore; pg = posterior gonopod; pl = pleurite; pz = prozonite; sb = sensilla basiconica; sp = spiracle; st = sternite. I–VII indicates the number of antennomeres. The white arrow on (B) indicates the row of striae at the anterior margin of the antennomeres and on (H) indicates the lateral, ridge-like extension of the prozonite. Scale bars: A, G, H = 100 µm; B, D–F = 20 µm; C = 10 µm.
