Unmounted material. Mature adult female dark purple, dorsal surface almost denuded of wax, some waxy tassels projecting from anterior and posterior apices. Ovisac smooth, very long, about 2 or 3 times as long as the body of the female (adapted from Cockerell, 1898a).

Slide-mounted material. Adult female elliptical, 3.9–5.4 mm long, 2.3–3.8 mm wide (lectotype of I. (Proticerya) littoralis 5.4 mm long, 3.8 mm wide; lectotype of I. littoralis mimosae 5.1 mm long, 3.3 mm wide; lectotype of I. littoralis tonilensis 3.9 mm long, 2.3 mm wide). Antennae 9 segmented. Eyes, mouthparts and legs as for tribe. Thoracic spiracles as for genus; derm at atrial opening with 3–6 simple multilocular pores, each 10–11 µm in diameter, with bilocular centre and 9–12 outer loculi. Hair-like setae distributed as for genus; longest setae forming marginal clusters on each segment and between antennae. Flagellate setae distributed as for genus. Simple multilocular pores, each 12–13 µm in diameter, with bilocular or trilocular centre, forming dorsal medial longitudinal row on head and thorax and marginal clusters on venter; similar pores, each 10–12 µm in diameter, with bilocular centre (less often trilocular) and 6–9 outer loculi, scattered on rest of dorsal surface and marginal to submarginal venter. Ovisac band present, formed by dense setae, each 75–100 µm long, with round to flattened bases and by multilocular pores of two types: (i) larger pores forming inner band 7–9 pores wide, each pore 11–13 µm in diameter, with bilocular or trilocular centre and 6– 12 outer loculi, and (ii) smaller pores forming outer band 3–5 pores wide, each pore 9–10 µm in diameter, with bilocular centre and 3–8 outer loculi, appearing slightly bluish when stained. Multilocular pores, each 11–12 µm in diameter, with bilocular or trilocular centre and 2–5 outer loculi, scattered on ventromedial to submedial head and thorax; similar pores, each 12–13 µm in diameter, with bilocular centre and 4–6 outer loculi, scattered across medial to submedial abdomen. Vulvar opening as for genus, surrounded by typical multilocular pores, each 12–13 µm in diameter. Cicatrices oval to round, numbering 3, centre cicatrix larger than lateral cicatrices. Abdominal spiracles as for genus. Anal ring as for genus; anal opening as for genus, surrounded by hair-like setae and typical multilocular pores each 11–12 µm in diameter.

First-instar nymph as for genus, except each dorsal abdominal segment with one submarginal pore, two submedial pores and one medial pore; dorsal head and thorax with dense multilocular pores; long hair-like setae at abdominal apex in three pairs.

Taxonomic notes. Refer to the taxonomic notes of C. genistae and the C. littoralis group for a discussion of similar species.

We examined the type material of the two subspecies, I. littoralis mimosae and I. littoralis tonilensis and found no difference between those specimens and specimens of I. (Proticerya) littoralis . The World Catalogue provided incorrect type data for Icerya littoralis littoralis ( Ben-Dov, 2005: 198) . The correct type data are provided above.
