GENERAL

Detailed description and illustration of adult female and first-instar nymph by Gullan, P.J. & Strong, K.L. 1997. Scale insects under eucalypt bark: a revision of the Australian genus Phacelococus Miller (Hemiptera: Eriococcidae). Australian Journal of Entomology 36: 229–240.

SYSTEMATICS

Slide-mounted adult female with: enlarged setae absent; hair-like setae scattered over dorsal surface; dorsal multilocular pores present marginally; ventral multilocular pores in clusters on abdomen and near spiracles only; cruciform pores present on dorsum only; antennae 7-segmented; macrotubular ducts present; microtubular ducts medium in length, with 1 sclerotized area (see Gullan, P.J. & Strong, K.L. 1997. Scale insects under eucalypt bark: a revision of the Australian genus Phacelococus Miller (Hemiptera: Eriococcidae). Australian Journal of Entomology 36: 229–240).

BIOLOGY

Four of the adult females from E. sideroxylon tricarpa were collected together in a cavity within swollen stem tissue and were covered in a resinous or waxy substance. The fifth specimen was taken from the arm of a gall of Apiomorpha munita tereticornuta. The specimens collected by Beardsley were in amorphous white tests, which he described as waxy on one label, and were either on bark (some adult females) or in crevices in twig bark (both adult and second-instar females) (see Gullan, P.J. & Strong, K.L. 1997. Scale insects under eucalypt bark: a revision of the Australian genus Phacelococus Miller (Hemiptera: Eriococcidae). Australian Journal of Entomology 36: 229–240).
