Remarks

• Systematics: It would be hard to confuse full-grown adult females of M. megaventris with any other scale insect, due to the grossly distended venter. Adult females of M. megaventris are most similar morphologically to those of M. meander and M. cunicularius. Sequence data recovered strong support for a sister-group relationship between M. megaventris and M. meander, the only two species from Australia known to induce galls on Nothofagus. (Hardy, et al., 2008)
• Structure: Adult female body outline oblong, greatly expanded venter extending forward far beyond sclerotic dorsum. Eyespot either incorporated into sclerotic dorsal derm, or just ventrad of it. Antennae 6-segmented. (Hardy, et al., 2008)
• Biology: The adult female of M. megaventris induces finger-like galls on the leaves of N. moorei. The dorsum is flat and plugs the gall opening and the venter is expanded to fill the gall cavity. (Hardy, et al., 2008)
• General Remarks: Detailed description and illustration in Hardy, et al., 2008.
