Remarks

• Systematics: Thysanofiorinia leei differs from T. nephelii in lacking the prominent median lobes in the adult female and in possessing 6 pairs of gland spines on the 3rd and posterior segments whilst in T. nephelii they number only 3 pairs situated on the pygidium only (Williams, 1971).
• Structure: Adult female retained within the exuviae of the 2nd stage which forms the scale. Scale is subcircular to oval, pale yellow brown with the prominent exuviae of the 1st stage of the same color and lying at one end. Adult female ovoid, about 0.7 mm long, membranous except for slightly sclerotized pygidium and an area between the anterior and posterior spiracles which is also slightly sclerotized containing derm granulations. Pygidium rounded without noticeable lobes except for two small short projections each with dentate distal edge representing the median lobes, these separated by a space equal to about twice the width of one lobe, the space forming a wide and shallow notch (Williams, 1971).
• General Remarks: Detailed descriptions and illustrations by Williams (1971) and Takagi et al. (1989).
