Remarks

• Systematics: P. wilga is the only species of Poliaspis to have only the median lobes present. It can also be recognized by the loose groupings of more than 2 marginal ducts on abdominal segments 6 and 7. (Hardy & Henderson, 2011)
• Structure: Pygidium with only a single pair of distinct lobes, the median pair short, about as broad as long, distal margin broad, notched on mesal and lateral margins; plates arranged 2, 3, those of median incisura short and small, hardly longer than median pair of lobes, those of each lateris much longer and arranged singly and distant from each other; margin of lateris thickened, toothed (MacGillivray, 1921).
• General Remarks: Detailed description and illustration by Borchsenius & Williams (1963).
