Remarks

• Systematics: GenBank accession numbers KY219523 (D2086B), KY219517 (D2061B), GQ325555 (D2050A), KY219553 (D2134A); elongation factor 1-alpha (EF-1α), GQ403912 (D2050A); cytochrome oxidase I and II (COI–II), GQ425090 (D2050A); and the small ribosomal subunit (16S) of the primary endosymbiont (Uzinura diaspidicola), GQ424923 (D2050A), KY220384 (D2086B).

  Lindinger (1943a) moved "casuarinae" Maskell 1893b into the genus Poliaspis, however the species Poliaspis casuarinae Lidgett 1898a already existed. Because P. casuarinae Lidgett was a newer name, Lindinger replaced it with P. casuarinicola. The most distinctive feature of A. casuarinae is the presence of 1 or 2 marginal macroducts between L1. The only other species of Albastaspis with this character is A. brevis; A. casuarinae can be distinguished from A. brevis by elongate-oval body shape (body turbinate in A. brevis) and by the absence of antennal setae (present in A. brevis) and of pores by the posterior spiracle (present in A. brevis).

• Structure: Female scale snowy white, convex, elongate, narrow. Exuviae terminal, orange-red. Male scale narrow, elongate, more flat than that of female, but without sign of carination, greyish; exuviae yellow. Adult female brown, elongate (Maskell, 1893b). Redescription in Wei, Normark & Normark, 2026. Adult female not pupillarial. Scale cover “snowy-white, convex, elongated, narrow,” with “terminal, orange-red” exuviae (Maskell 1893: 209). Slide-mounted adult female (n=12) 600–1120 μm long, 380–640 μm wide, broadest at metathorax and abdominal segment I. Body outline elongate-oval, derm membranous except for pygidium, pygidium narrow and elongate.
• General Remarks: Best description and illustration by Maskell (1893b). Redescription and illustration in Wei, Normark & Normark, 2026.
