Icerya callitri (Froggatt)

Llaveia callitri Froggatt, 1923: 162 .

Icerya callitri (Froggatt) ; Morrison (1928: 189).

Unmounted material. Adult female enveloped in mass of loose cotton woolly secretion, only tarsi are visible. Body of adult female, denuded of wax, bright orange-yellow; legs, eyes and antennae black (adapted from Froggatt, 1923). In life, young adult female from near Binya in New South Wales (see 'Other material examined') covered in loose white wax dorsally and laterally, with one dense wax tuft arising from area of each thoracic spiracle, a skirt of white wax ventromarginally covering ovisac band and area within ovisac band completely devoid of wax.

Slide-mounted material. Adult female elongate to oval, 4.5 mm long, 4.0 mm wide. Antennae 11 segmented. Eyes, mouthparts and legs as for tribe. Thoracic spiracles as for genus. Hair-like setae dense on ventral head, thorax and marginal abdomen, forming dense clusters on dorsal head and thorax, scattered across abdomen. Flagellate setae as for genus. Open-centre pores, each 14–16 µm in diameter, 13–14 µm long, with 6–10 outer loculi, forming marginal clusters and sparse clusters on dorsal submedial head and thorax. Dorsal surface and ventral head and thorax covered with simple multilocular pores of two types: (i) pores, each 9–10 µm in diameter, with bilocular centre and 6–12 outer loculi, forming submedial and submarginal clusters on dorsal head and thorax; dorsal submedial, submarginal and marginal clusters on abdomen; ventral clusters on head and thorax; and (ii) pores, similar to vulvar pores and appearing bluish when stained, each 11–13 µm in diameter, with bilocular, trilocular or quadrilocular centre and 10–12 outer loculi, covering derm on dorsum surrounding previously described pores, covering ventral head and thorax and in marginal clusters around ovisac band on ventral abdomen. Ovisac band, 6–8 pores wide, made of simple multilocular pores, each 9–10 µm in diameter, with bilocular centre and 10–12 outer loculi. Simple multilocular pores, each 8–9 µm in diameter, with bilocular (appearing reniform) centre and 4 outer loculi, scattered across ventromedial abdomen. Vulva as for genus, surrounded by typical pores, each with bilocular or trilocular centre and 10–14 elongate outer loculi. Cicatrices large, hourglass shaped, numbering 3, subequal in size or central cicatrix largest. Abdominal spiracles in 2 pairs. Anal tube as for genus; anal opening as for genus, surrounded by robust hairlike setae and typical multilocular pores.

Taxonomic notes. Refer to the “ Pericerya ” group for discussion of similar species.

We looked for the type specimens of L. callitri at ANIC and ASCU and did not find material with correct collection data. This species has only ever been collected on Callitris spp.
