Key to puparia of Aleurocanthus species from Taiwan

1. Puparium pale, dorsal spines with laciniate apices ( Fig. 53 )............................................. A. rugosa

-. Puparium black, apex of spines pointed or bifurcated......................................................... 2

2. Glandular spines present only on submargin and first abdominal segment, apex of spines bifurcated, none of them reaching well beyond margin; dorsum with prominent pores ( Fig. 28 ); operculum filling half the length of orifice; ventral subdorsum with band of spinules.......................................................................... A. eugeniae

-. Glandular spines present on all the dorsal areas, apex of spines pointed, most of them reaching well beyond margin; operculum almost filling the orifice; venter without dense spinules........................................................ 3

3. Vasiform orifice transversely elliptical in female puparia and subrectangular in male puparia; abdominal submedian spines almost uniform in size; marginal teeth much chitinised; submarginal spines on abdomen placed in transverse rows with closely placed bases of two to four spines; host plant Cinnamomum osmophloeum ( Fig. 32 )................ A. lauriphaga sp. nov.

-. Vasiform orifice cordate in both female and male puparia; abdominal submedian spines not uniform in size; usually the 4th and 7th pairs of spines longer than other submedian pairs; marginal teeth concolourous with remainder of cuticle; submarginal spines not placed in transverse rows, but bases of posterior-most 2nd and/or 3rd submarginal spines placed close together.... 4

4. Margin toothed; submargin with 11 pairs of spines, of which five pairs on cephalothorax; none or only one pair of the submarginal spines may be doubled at posterior abdominal area...................................................... 5

-. Margin crenulate; submargin with 15 or 16 pairs of spines, of which five pairs on cephalothorax; two pairs of submarginal spines may be doubled at posterior abdominal area........................................................... 6

5. Female puparium with 29 pairs of dorsal spines, of which 12 pairs on submargin; the 3rd posterior-most submarginal spines usually doubled at base......................................................................... A. woglumi

-. Female puparium with 30 pairs of dorsal spines, of which 11 pairs on submargin ( Fig. 55 ); all the submarginal spines placed singly..................................................................................... A. spiniferus

6. Transverse moulting suture turned anterolaterally; cephalic submedian/subdorsum with six pairs of spines; eye spots absent; none of the submarginal spines doubled at base ( Fig. 9 ); usually from Citrus species...................... A. citriperdus

-. Transverse moulting suture not turned anterolaterally; cephalic submedian/ subdorsum with 9 pairs of spines; eye spots slightly elevated; the 2nd and 3rd submarginal spines on posterior abdominal area doubled at base ( Fig. 1 ); usually from Lauraceae .............................................................................................. A. cinnamomi
