Systematics: Slide-mounted adult female with: enlarged setae elongate, apices acute, slightly curved, all about same size; last abdominal segment with cluster of 5 to 16 microtubular ducts on medial area of dorsum, macrotubular ducts absent from posteriomedial area of dorsum (Gullan & Vranjic, 1991). Eriococcus confusus Maskell (1892) is the senior secondary homonym of E. confusus Danzig (1962a). The name E. confusus Danzig has been replaced with E. danzigae.

Adult female is dull brownish-yellow to dark red, broadly oval and convex (Maskell, 1892) and densely aggregated (Vranjic, 1990). Crushed body contents are orange-brown. Adults crushed in 10% KOH solution are yellowish-brown at first, then turning greenish brown (Gullan & Vranjic, 1991).
Biology: Individuals densely aggregated with tests often appearing to coalesce. On smaller stems and midribs of leaves of many Eucalyptus species (Gullan & Vranjic, 1991).
