Remarks

• Systematics: Aulacaspis mali is close to A. latissima, but distinguishable by the quantity of cylindrical glands and the shape of the median lobes (Borchsenius, 1938). Kawai (1980) recorded A. mali from Japan but, in the view adopted in Takagi, 2017, what he identified with A. mali should represent another species, A. sorbi. These species are clearly distinguishable from each other in the characters of the median trullae and may not completely be the same in the occurrence of dorsal macroducts. (Takagi, 2017)
• Structure: Body of female reddish orange. L1 very broad, project beyond margin of pygidium more than inner lobule of L2. Outer lobule of L2 shorter than inner. L3 somewhat shorter than L2. Groups of dorsal macroducts located on III-IV abdominal terga: 8-10 on III, 4-7 on IV, 3 or 4 on V, 1 to 3 on VI; submarginal ducts on III-V: 6-10 on III and 3 or 4 on IV-V. 4 or 5 ducts each present along margin of II-III abdominal terga. Eggs reddish (Danzig, 1986a).
• Biology: Location of male scales near females a typical feature (Danzig, 1986a).
• Economic Importance: Miller & Davidson (1990) list this insect as a pest.
• General Remarks: Detailed description and illustration by Borchsenius (1938).
