Remarks

• Systematics: Madarococcus meander is most similar to the other gallinducing Madarococcus species, M. cunicularius and M. megaventris. All three species have 1, 6-segmented antennae; 2, a sclerotic dorsum; 3, relatively few dorsal setae; 4, an expanded venter, and 5, no ventral tubular ducts. Adult females of M. meander and M. cunicularius can be distinguished from those of M. megaventris by having 1, spatulate suranal setae (evenly attenuated in M. megaventris); 2, ventral lobe seta arising proximal of caudal seta (arising distal of apical seta in M. megaventris); 3, relatively few dorsal tubular ducts (numerous in M. megaventris), and 4, venter only moderately expanded (extremely expanded in M. megaventris). Adult females of M. meander can be distinguished from adult females of M. cunicularius by having 1, macrotubular ducts along the margin (in M. cunicularius macrotubular ducts are completely absent); 2, far fewer disc pores on the ventral surface of the abdomen (only a sparse submedial line as opposed to a broad submedial longitudinal band), and 3, a distinctive anal lobe shape: truncate apex and straight inner margin parallel to the longitudinal body-axis (the anal lobes of M. cunicularius are subconical and have rounded apices). (Hardy, et al., 2008) The first-instar nymphs of M. meander can be distinguished from the other Australian species of Madarococcus by the presence of only one disc pore near each anterior spiracle and the absence of microtubular ducts on the dorsal submedial areas of the abdomen. (Hardy, et al., 2008)
• Structure: White wax is extruded from between the anal lobes and around the margin of the body. The colour of the live female is yellowbrown, becoming darker with age. (Hardy, et al., 2008)
• Biology: The female of M. meander induces a small pit gall on the leaves of N. cunninghamii. The body of the female fills the leaf pit, with the female’s dorsum lying level with the top of the pit and becoming more sclerotized with age. The female is ovoviviparous and newly emerged crawlers do not shelter under female’s body before dispersing. (Hardy et al., 2008)
