Nomenclatural History

• Heathcotia Hardy & Beardsley 2011: 504. . accepted valid name

Remarks

• Systematics: Heathcotia is closely related to the genera Subcorticoccus and Fragorbis. All three described species of Subcorticoccus and three of the five described species of Fragorbis also occur under bark. The following features are shared by adult females of all three genera: (i) reduced appendages; (ii) a slightly recurved tarsal claw; and (iii) a simplified anal ring with few or no pores. Adult females of Heathcotia and Fragorbis by: (i) the distinct fringe of setae marginally (absent in Subcorticoccus and Fragorbis); and (ii) the cylindrical anal ring with eight setae (anal ring variously fragmented and usually with fewer than eight setae in Fragorbis, anal ring with only two setae in Subcorticoccus). Adult females of Heathcotia can be further distinguished from those of Subcorticoccus by lacking the characteristic longitudinal band of microtrichia on the head. (Hardy, et al., 2011)
• Structure: Adult female: body outline round to subquadrate. All appendages reduced: antennae seven-segmented, segments V and VI partially fused; legs short, tibia and tarsus partially fused, fore and mid legs about as along as spiracular apodemes, hind legs larger. Frontal lobes in form of broad, blister-like areas of cuticle present posteromedial of antennae. Labium composed of two fused segments. Anal opening on ventral body surface; anal ring in form of short cylinder, with only a few minute pores near base of each of the eight ring setae. Caudal setae absent. Dorsal derm nodulose, with conspicuous, sclerotic microtrichia. Dorsal setae minute, spinose with acute apices. Macrotubular ducts with sclerotic vestibule and fine ductule. Microtubular ducts present. Margin delineated with fringe of setae much longer than those on dorsum, each seta spinose, slightly curved, with blunt apex. Loculate pores quinquelocular. (Hardy, et al., 2011)
• Biology: Only adult females of the type species are known, and these were collected living cryptically beneath Eucalyptus bark. (Hardy, et al., 2011)
