(Gullan, P.J. & Vranjic, J.A., 1991) [26] (adult female; Australian Eriococcus species on Eucalyptus species)
GENERAL
Detailed description by Gullan, P.J. & Vranjic, J.A. 1991. The taxonomy of the gum tree scales Eriococcus confusus Maskell and E. coriaceus Maskell (Hemiptera: Coccoidea: Eriococcidae). General and Applied Entomology 23: 21–40.
SYSTEMATICS
Slide-mounted adult female with: enlarged setae slender to robust, slightly curved, tapering to pointed apex, scattered over dorsal surface. "The status of this taxon is uncertain It is very similar to E. coriaceus and may be a Western Australian geographical variant of E. coriaceus. The most notable differences are that specimens from Western Australia have few or no bilocular pores between the antennae, shorter dorsal setae, and more microducts dorsally on the abdomen than specimens of E. coriaceus from south-eastern Australia. Pigment colour is similar in the 2 taxa (see Gullan, P.J. & Vranjic, J.A. 1991. The taxonomy of the gum tree scales Eriococcus confusus Maskell and E. coriaceus Maskell (Hemiptera: Coccoidea: Eriococcidae). General and Applied Entomology 23: 21–40).
STRUCTURE
Sac is globular and very compact. They are well separated from each other and formed from a stout leathery delicate white secretion. Adult female reddish and rounded (see Froggatt, W.W. 1921. A descriptive catalogue of the scale insects (Coccidae) of Australia. (Part II [Concl.]). Science Bulletin, Department of Agriculture, New South Wales 18: 1–159). Dry adults turn intense scarlet to crimson in 10% KOH (see Gullan, P.J. & Vranjic, J.A. 1991. The taxonomy of the gum tree scales Eriococcus confusus Maskell and E. coriaceus Maskell (Hemiptera: Coccoidea: Eriococcidae). General and Applied Entomology 23: 21–40).
