Remarks
- Systematics: The species differs from its congeners in the presence of a submedial band of large, strongly sclerotised cylindrical wax glands and in the spiracular setae, which are similar in size to the marginal setae. (Gavrilov-Zimin, 2023a)
- Structure: Mature female enclosed in grey felt-like wax sac, excluding of median part of dorsum, which covered with plate of white dense wax. Body comparatively flat, broadly oval, up to 5 mm long in mature female, with membranous cuticle. Mouthparts and spiracles of usual structure characteristic of Coccidae. Eyespots present, unclear. Antenna 8-segmented, about 400 μm long. Legs distinct, without tibio-tarsal ly flat, broadly oval, up to 5 mm long in mature female, with membranous cuticle. Mouthparts and spiracles of usual structure characteristic of Coccidae. Eyespots present, unclear. Antenna 8-segmented, about 400 μm long. Legs distinct, without tibio-tarsal sclerotisation; claw without a denticle; claw digitules enlarged, with large apical knobs. (Gavrilov-Zimin, 2023a)
