Remarks

• Systematics: Live adult female occurs on underside of leaf near petiole. Body colour bright green, some specimens with longitudinal bands of brown cuticle, others with dorsum entirely brown. Glassy filaments (maximum length 0.2–0.3 mm) born on enlarged setae, projecting dorsally and marginally. The sequence data strongly support a sister-group relationship between M. cunninghamii and the Australian species M. moorei. Madarococcus cunninghamii would be most easily confused with M. pulchellus or M. viridulus. The slide-mounted adult females of these three species are similar in lacking macrotubular ducts on the dorsum, and having only enlarged dorsal setae. M. cunninghamii can be recognised by having 1, macrotubular ducts present posterolateral of the vulva; 2, apical lobe seta shorter than dorsoapical lobe seta, and 3, a 2-segmented labium. The three pairs of enlarged dorsal setae on the first instar nymph are unique among the nymphs of known eriococcids on Nothofagus.
• Structure: Body outline ovate to subcordate. Eyespot on or just dorsal of margin. Antennae 6-segmented.
• General Remarks: Detailed description and illustration in Hardy, et al. (2008).
