Remarks

• Systematics: P. serrula is clearly not a typical Parlatoria, but it is assigned to this genus until more is known of other closely allied genera. It bears a slight resemblance to P. aonidiformis Green and Parlaspis papillosa Green. It differs from both in the orientation of the pygidial marginal macroducts and the presence of bosses on the free abdominal segments. The pygidial lobes resemble those found in Parlaspis papillosa, but this species has no cicatrix-like structure. In Parlatoria aonidiformis, the pygidial lobes are of different form and although it has one or two cicatrix-like structures on either side these are on the 2nd abdominal segment and not in the vicinity of the anterior spiracles (Hall & Williams, 1962).
• Structure: Slide mounted adult female broader than long, about 0.7 mm broad and 0.6 mm long. Anterior spiracles with 1-3 pores. Thoracic gland tubercles usually only 3, between the anterior spiracles and margin. In the same vicinity, but on the dorsal surface is an 8-shaped cicatrix-like structure one part of which is larger than the other. Pygidium broadly rounded with 3 pairs of lobes; median lobes broad at base, parallel sided over the basal half, with a small, triangular, apically rounded terminal half; 2nd lobes of similar deeply notched form and slightly smaller; 3rd lobes smaller without a notch on inner edge, but with 2 or 3 on outer margin (Hall & Williams, 1962).
• Biology: Three specimens of P. serrula were found on some coconut material heavily infested with Pseudococcus citriculus Green (Hall & Williams, 1962).
• General Remarks: Detailed description and illustration by Hall & Williams (1962).
