The following additional information is added to the original description of
Meganathan and David (1994)
.
Puparium.
White, without secretion of wax; constricted at thoracic tracheal pores and posterior abdominal segments region; broadest across the first abdominal region (
Fig. 24
);
540–580 µm
long,
440–490 µm
wide.
Margin.
Crenulate (
Fig. 25
), 24–37 crenulations in 0.1 mm; thoracic tracheal pores indicated with deep invagination while caudal tracheal pore region indicated by shallow emargination. Anterior and posterior abdominal setae
17 µm
and
8 µm
long, respectively.
Dorsum.
Dorsum without any tessellation. Cephalothorax with three pairs of tubercles, one pair each on pro-, meso-, and metathorax on outer submedian area, and abdomen with six pairs of tubercles—one pair on each abdominal segment I and III–VII on outer submedian area. Median tubercles on abdominal segment I–VII faintly indicated. Submarginal lines irregular. Longitudinal moulting suture reaching margin and transverse moulting suture runs posteriorly and curves upwards and terminating near margin below the thoracic tracheal pores. Thoracic tracheal furrows absent while caudal tracheal furrow indicated (
Fig. 26
).
Vasiform orifice.
Subcircular,
29–37 µm
long,
31–34 µm
wide, notched at caudal end; operculum subcordate,
16–22 µm
long,
19–25 µm
wide. Lingula concealed.
Venter.
Paired ventral abdominal setae 7.5 µm long,
42–43 µm
apart; thoracic and caudal tracheal folds indicated. Antennae reaching base of prothoracic legs. Adhesive sacs and spiracles visible.
Chaetotaxy.
Cephalic setae
9 µm
long, eighth abdominal setae cephalolaterad of vasiform orifice,
5 µm
long and caudal setae
