Remarks

• Systematics: Pseudaulacaspis brimblecombei comes closest to Pseudaulacaspis chinensis in possessing numerous dorsal ducts, many of which, on the free abdominal segments, form supplementary rows. It differs in the form of the median lobes which are sunk into the apex of the pygidium whilst those of P. chinensis project as far as the apices of the 2nd lobes (Williams, 1973).
• Structure: Female scale silvery white or almost transparent, up to 4 mm long and 2 mm wide. Exuviae terminal, pale yellow. Male scale about 1.25 mm, same color, with a few light and dark longitudinal lines. Adult female fusiform, attaining a length of 1.75 mm, widest at the mesothorax or metathorax which are strongly lobed laterally; free abdominal segments also lobed laterally (Williams, 1973).
• Biology: Prefers the underside of leaves of its host plants. (Henderson, 2011)
• Economic Importance: In Australia it is a minor pest of macadamia nut production and in New Zealand it is a pest of ornamental proteas such as Telopea. Large populations of the scale can look spectacular, smothering the foliage and stems in white scales. (Malumphy & Halstead, 2012)
• General Remarks: Detailed description and illustration by Williams (1973). Redescription and illustrations by Henderson, 2011.
