Apical vesicle lacking, apical epicuticular expansion present. Re- maining setae simple. Sensory organ of third antennal segment consisting of two sensillae with alveolar surface and arising from a single base with lateral microsensilla and no guard sensilla (Figs 2, 5). Antennal segments I and II with 7 and 11 setae respectively. Ratio of antennal segments I: II: III: IV = 1:1 Ratio of antenna: cephalic diagonal = 1 Head square with 4 + 4 corneae, corresponding to posterior corneae E, F, G and H (Fig. 20).
