Keys

• WeiNoNo2026: pp.30-36 ( Adult (F) ) [species of Fioriniina in Australia]
• Hender2011: pp. ( Adult (F) ) [Key to Poliaspis adult females in combination with 1st-instar nymphs/exuvia in New Zealand]
• HardyHe2011: pp.4-6 ( Adult (F) ) [Key to species of Poliaspis (excluding P. intermedia, and P. casuarinicola)]

Remarks

• Systematics: GenBank accession number GQ325533), (Wei, Normark & Normark, 2026)

  The absence of large dorsal cephalic ducts on the 1st-instar / 1st-exuvium distinguishes P. chathamica from all the other Poliaspis species found in New Zealand. (Henderson, 2011)

• Structure: Female scale cover white, exuvia terminal. Body shape fusiform with lateral abdominal lobes produced, rounded. Median lobes (L1) prominent, extending 50–70% beyond margin (length from a horizontal line at lateral body margin to lobe apex relative to total lobe length measured from exterior margin of yoke to lobe apex). (Henderson, 2011) Specimens from Queensland observed in Wei, et al., agree fairly closely with Henderson’s description and illustration of P. chathamica from the Chatham Islands of Aotearoa New Zealand. Most, but not all, of the Queensland specimens differ from the type series of P. chathamica by having 2 furcate gland spines between L1 and L2 (1 simple gland spine in this position in the type series) and 1 or 2 furcate gland spines laterad of L2 (1 simple gland spine in the type series). (Wei, Normark & Normark, 2026)
