DESCRIPTION OF LARVA ( FIG. 4 )

Body yellowish brown; shiny, glabrous. Body length (without tubercles) 1.61 mm; width 0.68 mm ( Fig. 4 ).

Head armed with five tubercles, all simple and covered with scattered setae; frontal pair moderately short, slender, directed forward and subparallel; median tubercle stout, long and erect; occipital pair stout, long, suberect, and divergent.

Pronotum short and wide, with lateral margins expanded far from head on both sides, with median part swollen anteriorly, with a median longitudinal keel; armed with a pair of very short, suberect, divergent tubercles on swollen part; with a pair of long, suberect, divergent tubercles directed upward in the middle line across the keel; the margins armed on the anterior part with a few, short, tubercles, two long, simple, tubercles and two longer tubercles on the posterior part; all tubercles ending with a short seta at the apex.

Wing pads with some short tubercles, posteriorly with two long tubercles on each side, mesonotum armed at the middle with a pair of long, slender, divergent tubercles directed upward.

Metanotum armed with a pair of very short, slender tubercles directed backward. All thoracic tubercles are covered with scattered setae.

Abdominal tergites more slender than wing pads; fourth to ninth with a long simple tubercle on each side; first and second terga with paired, divergent tubercles directed backwards, the first pair long and the second pair very short; fifth, sixth and eighth terga with a long median tubercle; all abdominal tubercles covered with scattered setae.

REMARKS

Instar III and IV have a similar habitus as instar V. They are, however, smaller. The same combination of tubercles are resent in these two earlier instars but all tubercles are stouter when compared with other structures. Tubercles in the fifth instar are more slender.
