Icerya koebelei Maskell

Icerya koebelei Maskell, 1892: 184 [not Maskell (1893: 245), as in Ben-Dov (2005: 198)].

Unmounted material. Adult female bright red, dorsum covered with patches of mealy wax, often thick in some areas, forming a cylinder of wax nearly as long as body, projecting from middorsum; glassy filaments projecting from body; ovisac made of yellow wax, relatively short, scarcely extending from abdomen, and causing abdomen to appear raised (adapted from Maskell, 1893, and Morrison, 1927).

Slide-mounted material. Adult female oval, 3.7–4.4 mm long, 2.5–3.0 mm wide. Antennae 9 or 10 segmented. Eyes, mouthparts and legs as for tribe. Thoracic spiracles as for genus, derm outside atrial opening of anterior spiracles with cluster of 3 or 4 simple multilocular pores, posterior spiracles with cluster of 6 or 7 pores, each pore with bilocular centre and 6–8 outer loculi. Blackish, curly hair-like setae covering dorsal surface, densest across head and thorax, and clustered with open-centre pores around margin; scattered across ventral head and thorax. Flagellate setae distributed as for genus. Open-centre pores, each 16–18 µm in diameter, 15–17 µm long, with 6–8 outer loculi, forming marginal clusters and dense across dorsal head. Simple multilocular pores, each 9–10 µm in diameter, with bilocular centre and 6–8 outer loculi, covering dorsal surface; cluster of 30–50 pores on middorsum. Ovisac band made of simple multilocular pores of two types: (i) pores, each with bilocular centre and 8–10 outer loculi, forming inner band 3–5 pores wide at anterior edge, and in clusters of 10–12 pores around lateral and posterior edges, and (ii) smaller pores, each with bilocular or trilocular centre and 4–6 outer loculi, forming outer band on anterior edge, 1 or 2 pores wide, and in segmental clusters on submarginal ventral abdomen. Simple multilocular pores, each 9–10 µm in diameter, with bilocular centre (appearing reniform) and 4 or 5 outer loculi, scattered on ventromedial head and thorax, and scattered across ventromedial to submedial abdomen. Vulva as for genus. Cicatrices round to oval, numbering 3, central cicatrix largest or all subequal in size. Abdominal spiracles in 2 pairs. Anal tube as for genus; anal opening as for genus, surrounded by long, robust hair-like setae.

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

The paralectotype slide present in the USNM collection is included because the collection number (“Mask. Coll. #283”) matches the collection number on one paralectotype slide from the NZAC.
