Remarks

• Systematics: Slide-mounted adult female with: enlarged setae slender, with truncate apex, scattered in small numbers over surface; 1 seta on each lateral margin of each abdominal segment; suranal seta spatulate; margins of anal lobes crenate (Hoy, 1962). Madarococcus argentifagi is very similar to M. rubrifagi. A distinction can be made between the two species on the basis of the apices of the enlarged dorsal setae: truncate, with broad concave apices in M. argentifagi, as opposed to blunt or truncate but never with concave apices in M. rubrifagi. M. argentifagi is also similar to M. nelsonensis and M. nothofagi. The adult females of M. argentifagi can be distinguished from those of M. nelsonensis by 1, lacking quinquelocular pores between hind coxae (several present in M. nelsonensis), and 2, having hind legs approximately same size as fore and mid legs (hind legs much larger than fore or midlegs in M. nelsonensis). Adult females of M. argentifagi differ from those of M. nothofagi by having 1, caudal seta longer than dorsoapical lobe seta (caudal seta shorter than dorsoapical lobe seta in M. nothofagi) and 2, 7-segmented antennae (6-segmented in M. nothofagi). (Hardy, et al., 2008)
• Structure: Hoy (1962a) described the adult female of M. argentifagi as lacking translucent pores on the hind legs, but translucent pores are present. (Hardy, et al., 2008)
