( Figs. 1 h, 2i, 3h, 4h)

First instar. Body: length 10.0 mm, width (prothorax) 3.0 mm; with uniform pile of fine short setae; prosternal setae absent. Primary setal pattern: 10 HPA, 0 PD, 3 PSL, 0 MSD, 2 MSL, 0 MTD, 2 MTL, 1 TM, 1 TSM, 1 TL, 1 AV9 ( Table 2 ), with the addition of an extra pair of TD setae in all abdominal segments. Head: covered with uniform pile of short, golden setae; epicranial suture short; frontal sutures extend to the base of the antennae; width of head capsule 2.0 mm ( Fig. 1 h). Mandibles with micro-asperities in the ventral base. Maxillary stipes with 17 micro-conical projections ( Fig. 2 i).
