Remarks

• Systematics: Aulacaspis pellucida is similar to Aulacaspis varicosa, but A. pellucida seems to be distinct owing to its thin, transparent and smaller scale (Robinson, 1917). Adult female body growing to the vitis-type, but often remaining fusiform or with mesoo- and metathorax not remarkably expanded laterally. Anterior spiacles each with a small cluster of disc pores; posterior spiracles with no dis pores. Geographically, this species is considerably variable in the total number of the dorsal macroduts and also in that of the perivulvar disc pores. A. pellucida may be closely related to A. binunga, from which it is easily distinguishable in having no dorssal macroducts on the seond abdominal segment. It also appears to be closely related to Aulacaspis guioae, which occurs on Guioa. (Takagi, 2012a)
• Structure: Female scale slightly elongated, about 2 mm long, or 1.5 mm in diameter, white, transparent and thin, showing the shriveled insect beneath. Exuviae terminal, yellow to brown, second skin broad-oval, first skin projecting beyond scale. Adult female pale yellow, almost colorless, oval, broadest across the middle. Male scale white, sides parallel, distinctly tricarinate, exuvia pale yellow, about 1 mm long (Robinson, 1917).
• Biology: Females and males occurring on the leaves and other parts of the host plants, sometimes causing shrinkage on the leaf surface. Female tests various in outline according to feeding sites, thin. Male tests tricarinate. (Takagi, 2012a)
• General Remarks: Best description and illustration by Robinson (1917). Recent description and illustration in Takagi, 2012a.
