Icerya rosae Riley & Howard, 1890a: 333 .

Icerya (Crypticerya) rosae Riley & Howard ; Cockerell (1895: 15).

Unmounted material. Adult female broadly oval and densely covered with a short secretion which forms a series of close plaits around the margin. The waxy secretion often has a yellowish tinge. Beneath the wax, the head and thorax are black with red around the margins and the abdominal dorsal and ventral surfaces are bright red. Antennae, legs and eyes black. Lacking an ovisac. Segments clearly marked, abdomen with a broad rounded subdorsal ridge. Females become more rounded with age (adapted from Riley & Howard, 1890b).

Slide-mounted material. Adult female elliptical, 3.6–4.0 mm long, 3.0– 3.4 mm wide (lectotype 4.0 mm long, 3.0 mm wide). Antennae 11 segmented, setae on apical segment up to 200 µm long. Eyes, mouthparts, legs and thoracic spiracles as for genus. Short hair-like setae evenly scattered on dorsal surface, longest setae around ventral margins. Flagellate setae distributed as for genus. Simple multilocular pores, each 8–9 µm in diameter, with bilocular or trilocular centre and 6–8 outer loculi, scattered across all body segments on dorsal surface; pores with trilocular centre found mostly on dorsal head. Simple multilocular pores, each 6–8 µm in diameter, with bilocular to trilocular centre and 6–9 outer loculi, on ventral margins of head and thorax. Simple multilocular pores, similar to vulvar pores, each 10–11 µm in diameter, with bilocular centre and 5–8 outer loculi on ventromedial head and thorax. Simple multilocular pores, similar to vulvar pores, each 10–11 µm in diameter, with trilocular centre (appearing elongate) and 6–10 outer loculi, scattered across ventromedial to submedial abdomen. Ovisac band absent. Marsupium absent. Vulvar opening as for genus, surrounded by typical multilocular pores, each 12–13 µm in diameter, with bilocular centre and 12–20 outer loculi. Cicatrices hourglass-shaped to reniform, numbering 3, central cicatrix largest. Abdominal spiracles as for genus. Anal ring as for genus; anal opening as for genus, surrounded by typical multilocular pores each 8–10 µm in diameter with round centre and 8–10 outer loculi. Tubercles absent.

First-instar nymph as for genus, except three pairs of long, hair-like setae at abdominal apex and anal tube with 8 multilocular pores at opening.

Taxonomic notes. Refer to the C. rosae group for discussion of similar species.

More type slides were discovered on a trip to USNM after Unruh & Gullan (2008) designated the lectotype and identified several paralectotypes. Those type slides are here recognized as paralectotypes and complete slide label data are provided above.
