Remarks

• Systematics: This species is similar to Aulacaspis herbae and A. discorum, grass-feeding species described from Sri Lanka by Green and from Pakistan by Hall and Williams, respectively. A. donacis and A. herbae are somewhat variable in body shape, and their broadest forms are especially closely similar. The known for of A. discorum has a similar but still broader body. A. donacis differs from A. herbae and A. discorum especially in the median trullae, which are, above all, non-zygotic. It is distinguishable also in having the marginal gland spines all single on the fifth to eighth abdominal segments (often paired on the seventh and eighth segments in the latter two species), in the submarginal dorsal bosses lacking on the fourth abdominal segment and occurring just laterally to the submarginal rows of macroducts on the third and fifth segments (present on the firsts and the third to fifth segments and occurring just measlly to the macroduct rows on the third to fifth in the latter two species), and n the wax-secreting organs generally fewer.
• Structure: Adult female Body somewhat variable in shape at full growth, usually obovate, with mesothorax broadest and prepygidial postsomatic segments gradually narrowing posteriorly, all these segments moderately lobed laterally, pygidium deltoid, little roundish on free margin; sometimes body narrower in various degrees (Takagi, 2016)
