Remarks
- Systematics: Slide-mounted adult female with: enlarged setae elongate, apices acute, slightly curved, becoming increasingly larger posteriorly; macrotubular ducts absent from posteriomedial area of dorsum; microtubular ducts sparse on dorsal abdomen, often in irregular transverse row on each segment (Gullan & Vranjic, 1991). Anal lobes each with 6 setae (Hoy, 1962).
- Structure: Adult female broadly oval. Crushed body contents reddish brown and crimson to scarlet in 10% KOH solution (Gullan & Vranjic, 1991). Sac of female ovoid to globular in shape, varying from light yellow or buff to dark orange or red and are typically discretely spaced (Vranjic, 1990). Sac of male pupa of similar color, but smaller. Adult female is dark red and fills the sac (Maskell, 1893b).
- Biology: There are four or five generations each year in Adelaide Australia (Patel, 1971; Gough, 1975).
- Economic Importance: This species can cause severe dieback and even death of young eucalyptus trees (Hoy, 1962; Hockings, 1950; Elliott & de Little, 1985).
- General Remarks: Best description and illustration by Gullan & Vranjic (1991). Also described by Maskell (1893b). Type information provided by Deitz & Tocker (1980) and Gullan & Vranjic (1991). A.vcoriaceus has a group of seven polyhydroxyanthraquinones, which cause intense scarlet to crimson tint of the insect body, placed in alkali (Gavrilov-Zimin, 2019)
