Remarks

• Systematics: The adult females of Y. libeauae are unique within the Eriococcidae of the New World in having the following combination of character states: hind tibia longer than hind tarsus; macrotubular ducts with conspicuous loop attached to vestibule; hind coxae each covered in translucent pores dorsally; sensory setae restricted to distal two segments of each antenna; three sizes of microtubular ducts; multilocular pores forming large clusters on abdomen. (Miller & Stocks, 2022)
• Structure: Holotype, slide mounted 1.6 mm long, 0.9 mm wide (paratypes 1.3–2.5 mm long, 1.1–1.3 mm wide). Body oval (nearly rotund in some paratypes), anal lobes not protruding. Anal-lobe area difficult to discern, dorsally each with 3 flagellate setae including elongate anal-lobe seta (paratypes 2–4), 1 microtubular duct (paratypes 2–4); ventrally each with 2 or 3 flagellate setae including suranal seta and elongate anal-lobe seta (paratypes 3 or 4), 0 microtubular ducts (paratypes 0–4), and 13 and 19 5-locular pores (paratypes 25–30 5-locular pores). (Miller & Stocks, 2022)
• Biology: Specimens collected in Mexico were found under the bark of a tree that the local people called chinchona. We suspect that it may be a species of Cinchona which is the source of quinine used as a treatment for malaria. Bodies of the larger specimens were bright red and the body margin had a coating of white wax.
• General Remarks: Detailed descriptions and illustrations of adult female, second-instar female, second-instar male and first--instar nymph in Miller & Stocks, 2022.
