Key to puparia of all the known Minutaleyrodes species with distribution

1. Cephalus and metathorax each with a pair of greatly enlarged tubercles ( Figs 6 , 9 ); submargin with a row of minute setae; abdomen with pronounced median tubercles on segments IV–VI; vasiform orifice elongate subcordate, lateral margins forming well-defined rim, inner margins subparallel, ventral surface invested with numerous acute microtrichia ( Figs 8 , 11, 15 ); Andaman Island........................................................................ andamanensis sp. nov.

-. Cephalus and metathorax without a pair of greatly enlarged tubercles; simple tubercles may be present ( Figs 34 , 60 ); submargin without a row of minute setae; abdomen with median tubercles weakly developed ( Fig. 34 ) or absent ( Fig. 60 ); vasiform orifice subcordate, inner posterior margin of vasiform without microtrichia............................................. 2

2. Longitudinal moulting suture not reaching margin; tubercles absent on abdominal segments; Taiwan.. suishanus (Takahashi)

-. Longitudinal moulting suture reaching the margin; tubercles present on abdominal segments......................... 3

3. Margin-submargin with narrow band of polygonal reticulations ( Figs 57 , 62 ); cephalothorax with 2 pairs of tubercles ( Fig. 60 ); Andaman Island.......................................................................... whisper sp. nov.

-. Margin-submargin lacking polygonal reticulations; cephalothorax with 3 pairs of tubercles ( Fig. 34 )................... 4

4. Abdomen with four pairs of tubercles, one pair each on abdominal segment I and IV–VI; India, Taiwan...... minuta (Singh)

-. Abdomen with six pairs of tubercles, one pair each on abdominal segment I–VI; India....... indicus Meganathan and David
