AR 0.91; antennal blade slightly shorter than antennal flagelum ( Fig. 20 c). Dorsal sclerites of head as in figure 20a, clypeus 61 µm long. Pecten epipharyngis formed by toothed plates ( Fig. 20 b). Mandible 110–115 µm long, with apical and three inner teeth dark brown; dorsal tooth double; seta subdentalis slender, 28 µm long ( Fig. 20 d).
