Remarks

• Systematics: Phylogenetic analyses based on both morphological and molecular data place M. totarae well outside of the Nothofagus-feeding clade of eriococcids. The suranal setae of adult females of M. totarae are not spatulate (mostly spatulate in Madarococcus), and only one size class of quinquelocular pores is present on the venter (two size classes present in all but one of the Madarococcus species lacking spatulate suranal setae). Therefore, Hardey, et al. 2008 transfers M. totarae out of Madarococcus and leaves it unplaced (as incertae sedis) until its relationships can be better studied. It appears to be related to some other New Zealand species that feed on Podocarpaceae and currently are placed in Eriococcus. (Hardy, et al. 2008) Slide-mounted adult female with: enlarged setae conical, short, sides slightly concave, apices rounded, marginal setae conspicuously larger than other dorsal setae, 2 lateral setae on margin of each abdominal segment; microtubular ducts elongate, without sclerotized area (Hoy, 1962).
• Structure: Adult females are elongate oval, convex, dark brown to green in color and do not form a sac (Hoy, 1962) and cluster on stems and in leaf axils (Esson, 1994). Female of second stage usually red, sometimes green or yellow, elliptical, convex above. First instar yellow, flattish, elliptical, segmented. Male has a snowy white sac of very loose texture (Maskell, 1890).
• Economic Importance: Esson (1994) reports that some young Podocarpus totara in New Zealand displayed apical die back and severe distortion of infested lower branches and twigs.
• General Remarks: Detailed description and illustration by Hoy (1962).
