Remarks

• Systematics: Important distinguishing characters of this species are the almost continuous rows of small ducts across the metathorax and first 3 abdominal segments, and the unusually long gland spines on the pygidium. Another species with similar gland spines is P. centreesa, but it possesses numerous spicules on the ventral surface and lacks the continuous rows of ducts anterior to the pygidium which are present in P. multiducta (Williams & Watson, 1988).
• Structure: Female scale elongate, brilliant white, exuviae yellow-brown. Adult female narrowly elongate, longest specimens 1.5 mm long, free abdominal segments moderately developed, head rounded. Pygidium elongate with median lobes well developed, divergent and wide, straight or rounded, giving the lobes a squat appearance; each lobe with distal edge notched; median lobe bases recessed into apex, forming a notch. 2nd lobes prominent, bilobed, each lobule rounded, inner lobule longer than median lobes. 3rd lobes represented by notches on margin (Williams & Watson, 1988).
• General Remarks: Detailed description and illustration by Williams & Watson (1988).
