Remarks

• Systematics: Poliaspis syringae is close to P. media, but the median pair of lobes are larger and rather more protruding (Laing, 1929). P. syringae is most similar to P. naamba and P. waibenensis. Adult females of P. syringae can be distinguished from those by (1) median lobes much larger than second lobes (similar in size in P. naamba and P. waibenensis); and (2) second lobes without basal sclerosis (present in P. naamba and P. waibenensis). (Hardy & Henderson, 2011)
• Structure: Female scale snowy white, smooth, shining, broad in front, tapering behind; exuviae pale brownish yellow, occasionally with a faint orange tint, terminal. Male scale snow white, surface presenting a somewhat woolly appearance, more or less parallel-sided, or slightly broader in front and tapering gently posteriorly, non-carinated; exuviae very pale yellowish brown. Adult female clearing completely in potash, broadly ovate (Laing, 1929). Slide-mounted adult female body outline oval, margin of thorax and abdomen undulate. Pygidium with 2 pairs of lobes; median lobes large, zygotic, divergent, connected via a narrow strap, each lobe wider than long, apex rounded and dentate; margin between lobes incised; second lobe bi-lobed, lateral lobule minute, each lobule with rounded apex, basal scleroses absent. (Hardy & Henderson, 2011)
