Systematics: Slide-mounted adult female with: enlarged setae conical, sides straight, apices slightly rounded, marginal setae conspicuously larger than other dorsal setae, 2 or 3 lateral setae on margin of each abdominal segment; suranal seta spatulate; microtubular ducts medium in length, without sclerotized areas (Hoy, 1962). Hoy (1962a) mistakenly described dorsal macrotubular ducts on the adult female, but these occur along the ventral submargin in the holotype. Likewise, Hoy described the anal ring as having six setae, but eight are present. Hoy (1962a) did not record the location of the adult females on their host. Recent collections confirm that they do not form a test and are either 1, wrapped around buds at nodes, with the last few abdominal segments curled and the more anterior parts more convex and sclerotized, or 2, on the underside of leaves, becoming highly convex with a brood chamber beneath. Madarococcus montifagi is most similar to M. detectus. (Hardy, et al., 2008)
Structure: Females do not form a sac. Adult female is rotund, very convex (Hoy, 1962).
