Unmounted material. Body of mature adult female bare of visible wax, dorsum orange and purple with lon-

gitudinal rows of black spots; young adult female covered in powdery white wax with four dorsal longitudinal rows of exposed orange-reddish spots on derm; legs, antennae and eyes brownish-black; adult female convex dorsally becoming very rounded with age, with distinct segmentation visible on dorsal surface; adult female deposits eggs beneath concave body.

Slide-mounted material. Adult female elongate to oval, 5.8–9.4 mm long, 3.4–6.0 mm wide. Antennae 11 segmented. Eyes, mouthparts and legs as for tribe. Thoracic spiracles as for genus; derm outside atrial opening with cluster of 15–20 simple multilocular pores, each with bilocular centre and 6–8 outer loculi. Robust hair-like setae scattered on derm, dense on ventral surface, longest setae in medial clusters on dorsal surface and clustered around ventral margin and between antennae. Flagellate setae as for genus. Open-centre pores absent. Simple multilocular pores, each 12–13 µm in diameter, with thickened outer rim and bilocular or trilocular centre and 6–8 slightly reniform outer loculi, covering dorsal surface and forming marginal band around ventral surface. Ovisac absent. Marsupium absent. Simple multilocular pores, each 12–13 µm in diameter, with thickened outer rim, bilocular centre and 4 slightly reniform outer loculi, covering ventromedial to submarginal derm, densest around mouthparts and around thoracic spiracles. Vulva as for genus, surrounded by hair-like setae and typical simple multilocular pores, each 12–13 µm in diameter, with thickened outer rim, bilocular or trilocular centre and 6–10 elongate outer loculi. Cicatrices large, hourglass-shaped, numbering 3, subequal in size. Abdominal spiracles in 3 pairs. Anal tube as for genus; anal opening as for genus, surrounded by short hair-like setae and typical simple multilocular pores with thickened outer rim, bilocular or trilocular centre and 8–10 elongate outer loculi. Dorsal surface becoming sclerotized with age; sclerotized patches present in transverse intersegmental rows across dorsal surface of each segment and on ventral surface of abdomen, largest patches on dorsal submedial head and thorax.

Type data. AUSTRALIA: Western Australia, Swan River , ex Acacia hueglii (George Compere)     .

Type material. Holotype: ad ♀, “near/ Icerya   ./On Acacia hueglii   / Swan River , West/ Australia./ Coll. Geo. Compere /#950” ( USNM)   . Paratype: 1 st -instar nymph, “ Auloicerya   /acaciae/On Acacia hueglii   / Swan River , West/ Australia./ Coll. Geo. Compere /#950” ( USNM)   .

Taxonomic notes. This species resembles I. australis   , but can be separated by the shape of the pores on the derm and by the presence of dense robust setae on the ventral margin and clustered on the middorsal surface.

The slide envelopes of both the holotype and paratype have written on them “ Auloicerya   new genus ”// “acaciae new species ”//“H.M. I-20-22”. The slides do not have an original holotype or paratype label, but Morrison & Morrison (1923) designated the adult female as the holotype and first-instar nymph as the paratype.
