Fig. 2. Aleurocanthus multispinosus sp. n. a, Sec- 
ond instar larva; b, third instar larva; c, pupal case; 
d, pupal case, vasiform orifice and caudal margin; e, 
I pupal case, margin. (Scale in mm.) 
spines. Abdomen with 3 pairs of short conical 
spines and 2 pairs of long spines. Eighth ab- 
dominal setae and caudal setae long, hairlike. 
Third instar (Fig. 2b): Length 0.54 mm., 
width 0.31 mm. Colour pale. Cephalic area with 
2 pairs of long spines anterior to cephalic setae, 
lateral pair shorter. Thorax with 2 pairs long 
spines anteriorly, lateral pair shorter; 2 pairs 
of long spines posteriorly. Abdomen: 1 pair of 
paramedian processes on 1st segment, followed 
by 1 pair of long spines, 3 pairs of pores, 2 
pairs of long spines. Eighth abdominal and 
caudal setae hairlike. 
PUPAL CASE (Figs. 2 c-e): Length 1.0 mm., 
width 0.71 mm. Colour black. Shape elliptical, 
wider behind mid-length, posterolateral mar- 
gins slightly concave and caudal region bluntly 
conical. No constriction across thoracic tracheal 
folds and no caudal invagination. Margin (Fig. 
2d) regularly toothed, teeth not broad and 
rounded but acute and pointed with the slope 
of the sides concave. Submargin not defined by 
submarginal line, finely ridged near margin. 
Thoracic and abdominal tracheal folds, clefts, 
pores, and combs absent. Cephalic area with 5 
pairs of long, black, somewhat frayed spines 
anterior to 1 pair of short finer paramedian 
cephalic setae. Eye spots not evident. Thoracic 
area with 5 pairs of long spines and 1 short 
thornlike spine midway between median line 
and margin metathorax. Abdomen with ill-de- 
fined median ridge, segmentation ill-defined, 
rhachis absent. Segment 1 with a pair of para- 
median processes. Segments 2-6 each with 1 
pair of short thornlike paramedian spines. Seg- 
ment 7 with long spines. Eighth segment with 
1 pair of long stout spines, setae absent. Caudal 
setae short, hairlike, with bases about same 
width as vasiform orifice but nearer the margin 
than to the orifice. Five pairs of long lateral 
spines in same line as 8th abdominal spines 
and 3 pairs of long discal setae midway between 
paramedian and lateral spines. Vasiform orifice 
(Fig. 2e) raised, not clearly discernible, hem- 
ispherical. Operculum filling orifice. Lingula not 
discernible. 
HOLOTYPE: Pupal case on slide mount. De- 
posited in Institut Francais d’Oceanie, Noumea, 
New Caledonia.
