Diagnosis. Length: 6.50–8.00 mm; width: 5.70–7. mm. Form (Fig. 20a) broadly circular, dorsum hemispherical, strongly convex. In live adults, ground colour bright lemon yellow with prominent black spots on pronotum and elytra (Fig. 21b–f), ventral side yellow except apical half of meso-and metaventrites and abdomen black. Head, pronotum and elytra with characteristic, strongly microreticulate sculpture between punctures. Posterior margin of ventrite 5 in female sinuate and produced medially backwards. Male genitalia (Fig. 20g –i) as illustrated; female genitalia with sperm duct originating below apex, ventrally on bursa, spermatheca (Fig. 20f) as illustrated.
Distribution. India: Northeastern region (Arunachal Pradesh, Assam, Manipur, Nagaland, Sikkim, Uttarakhand, Uttar Pradesh, West Bengal); Bhutan; Nepal; Tibet; Myanmar; Thailand; China.
Prey/associated habitat. All known hosts are aphids and include Macrosiphoniella artemisiae (Boyer de Fonscolombe), Rhopalosiphum maidis (Fitch), Taoia indica (Ghosh & Raychaudhuri), and Tuberculatus indicus Ghosh; found on Alnus nitida and Juglans regia; occasionally found in oak (Quercus serrata) farms (Singh and Singh, 1985).
Devi (1989) recorded it as a predator of aphids infesting oak in Nagaland, particularly Eutrichosiphum dubium (van der Goot) (as Holotrichosiphon dubius) on Quercus dealbata and Cervaphis quercus Takahashi on Quercus serrata.
Seasonal occurrence. Active during May–July, October–December in north and northeastern India (Singh & Singh 1985; Devi 1989).
Notes. Kapur (1963a) recorded it from the Himalayas (Sikkim). Miyatake (1985) and Ren et al. (2009) illustrated the male genitalia.
