Remarks

• Systematics: Pseudaulacaspis papulosa is so close to P. hilli that there may be some justification in uniting them. In all the material at hand of P. hilli, however, the ventral spicules are few, represented by 2-4 large ones on the mesothorax and 2 on the metathorax, with only 1 or 2 that are minute in the same areas. In P. papulosa they are abundant in the median areas, reaching as far forward as the labium (Williams & Watson, 1988).
• Structure: Female scale elongate, convex, edges often wrapped around branchlets; white, exuviae yellow-brown. Adult female fusiform, about 1.85 mm long; anterior end narrow but rounded, free abdominal segments with lateral lobes distinct but not well developed. Pygidium with median lobes separated by a space equal to width of 1 lobe, narrowly yoked at base; each lobe almost quadrate, the distal edge usually with 2 deep notches present. 2nd lobes much smaller than median lobes, the lobules elongate and rounded, often covered by overlapping pygidial margins, and recognizable by the presence of ventral paraphyses. 3rd lobes represented by serrations of margin (Williams & Watson, 1988).
• General Remarks: Detailed description and illustration by Williams & Watson (1988).
