Diagnosis. Length: 4.20–5.16 mm; width: 3.54–4.35 mm. Form (Fig. 176a) broad oval to slightly elongate oval, dorsum moderately convex and glabrous. Ground colour red to orange yellow, with black markings on head, pronotum and elytra. Head yellow, with a transverse black marking in posterior half. Pronotum with a transverse black band along posterior margin, rarely with four black spots. Elytral pattern highly variable (Fig. 178c–n); with an anchor-shaped black marking (Fig. 177a) very similar to that in P. dissecta in various states of reduction (Fig. 178c–f, m, n) / with broken lines (Fig. 176a) / with 10–11 elytral spots (Fig. 178g –l) / with immaculate elytra (Fig. 177b). Male genitalia (Fig. 176b–e) and spermatheca (Fig. 177c, d) as illustrated.

Immature stages. Life stages (Figs 178a, b; 179) as illustrated.

Distribution. India: Widely distributed in the northern and northeastern regions and the Himalayas (Andaman Islands, Arunachal Pradesh, Assam, Himachal Pradesh, Jammu & Kashmir, Manipur, Meghalaya, Sikkim, Tripura, Uttarakhand, Uttar Pradesh, West Bengal); Nepal; Bhutan; Pakistan; Myanmar; China; Thailand; Tibet; Taiwan; Vietnam.

Prey/associated habitat. Hemiptera: Aphidoidea: Adelges spp., Aphis fabae Scopoli, Aphis craccivora Koch, Aphis gossypii Glover, Brachycaudus helichrysi (Kaltenbach), Brevicoryne brassicae (L.), Capitophorus formosartemisiae (Takahashi), Eriosoma lanigerum (Hausmann), Hyalopterus pruni (Geoffroy), Lipaphis pseudobrassicae (Kaltenbach), Macrosiphoniella sanborni (Gillette), Macrosiphum rosae (Linnaeus), Myzus persicae (Sulzer), Pineus sp., Rhopalosiphum maidis (Fitch), Sitobion rosaeiformis (Das), and Tuberculatus indicus Ghosh. Associated with adelgids feeding on silver fir and pine; indeterminate aphids on Artemisia sp., Spiraea sp. (label data). Found feeding on aphids infesting Galinsoga parviflora and Bidens pilosa along with P. luteopustulata (Sajan et al. 2019) .

Seasonal occurrence. Active during February–June; collected during September–December.
