URS long wide-shaped, 3.25–3.49 × of basal width, 1.14–1.26 × of 2 HT, with 12–15 accessory setae (Figs 2 D, 3 D); Ant. III – IV in alatae with 125–130, 9–12 round, protuberant secondary rhinaria, respectively; SIPH long clavate (Figs 2 F, 3 F), thin and cylindrical at basal 1 / 3, then distinctly expanded at distal 2 / 3, and then gradually attenuated to apex, apical part of SIPH with 5–8 rows reticulations, 0.25–0.28 × of body length; the SW SIPH 1.39–1.74 × of BW SIPH; cauda long conical (Figs 2 E, 3 G), 2.89–3.13 × of BW cauda, with 41–43 setae; first tarsal chaetotaxy: 5, 5, 5. Biology. The species alternates between Rhododendron (primary hosts) and Asteraceae (secondary hosts, including Anaphalis, Artemisia, Gerbera, Inula, and Senecio), but it has also been recorded on some atypical host plants (Eurya japonica, Morus alba, Oxalis corniculata) (Verma 1971; Chakrabarti et al. 1983; Favert and Aphid Taxon Community 2025). The aphid feeds on the underside of leaves of Senecio sp. and Anaphalis sp. without causing noticeable damage (Fig. 12), and has additionally been observed infesting Polygonum sp. in China. Distribution. India: Himachal Pradesh (Verma 1971; Chakrabarti et al. 1983), Uttarakhand (Chakrabarti et al. 1983), Uttar Pradesh (Chakrabarti et al. 1983), West Bengal (Basu 1964); Pakistan: Murree (Muhammad et al. 2024). This species is recorded here for the first time from China, in Xizang Autonomous Region.
