Remarks

• Systematics: Pseudaulacaspis leveri resembles some species of Aulacaspis, but there are 2 short setae present between the median lobes. They are difficult to see in some specimens, but the species is left in Pseudaulacaspis for the present. P. subcorticalis (Green) has a similar arrangement of dorsal ducts, and may be a close relative; but P. leveri has the median lobes recessed into the apex of the pygidium to form a notch, whereas the median lobes of P. subcorticalis are prominent (Williams & Watson, 1988).
• Structure: An elongate species; adult female about 0.9 mm long; pygidium and head rounded; body membranous except for pygidium; lateral lobes of free abdominal segments only moderately developed. Median lobes prominent but recessed into pygidium, forming a notch at apex, the inner edges longer than outer edges, each lobe rounded distally. 2nd lobes bilobed, much smaller than median lobes. 3rd lobes represented by serrations on margins. Gland spines arranged singly on each side of 5th and posterior segments. Ventral surface with numerous perivulvar pores present in 5 elongate groups (Williams & Watson, 1988).
• General Remarks: Detailed description and illustration by Williams & Watson (1988).
