Remarks

• Systematics: Laingaspis lanigera is unique in its pygidial characters, the multilobate nature of the lateral margin, the many rows of dorsal pores on the lateral area and running parallel with the margin (Laing, 1929). This species has the diagnostic distribution of perivulvar pores found among species of Poliaspis but differs in an important feature: namely, 1-barred ducts arranged in a dense marginal swath on the pygidial dorsum. (Hardy & Henderson, 2011)
• Structure: Female scales densely massed together on the host, entirely covered with a thick, snowy white, woolly looking secretion, rough and irregular in texture; when disinterred from the mass, the puparium short, broadly mytiliform, the actual covering shield, with the secretion removed, very thin, white and tissue paper like; exuviae very pale brownish yellow, entirely concealed by the white secretion, the larval and perhaps also the nymphal, pellicle with long, thin, white, dorsal threads curling above the general secretionary matter, 1.7 mm long. Male cover slightly wider behind than in front, non-carinated, pellicle exposed, free from secretion, pale brownish yellow, 1 mm long. Adult female dark brown to almost black, clearing completely in potash; cuticle soft, membranous; broadly oval (Laing, 1929).
• General Remarks: Descriptions and illustrations by Laing (1929) and Borchsenius & Williams (1963). Redescription and illustration in Hardy & Henderson, 2011.
