Diagnosis. Dark greenish or reddish Impatientinum with mostly dark, striped legs, black siphunculi and pale cauda. Aptera with height of antennal tubercles 0.7–0.8 × length of first antennal segment; secondary rhinaria on antennal segments: III 4–7, IV 0, V 0; siphunculi with reticulation on the apical fourth, length 0.9 of head width across eyes; cauda with bluntly pointed apex; antennal PT/BASE 6.2–6.4.

Distribution and ecology. Present on the undersides of leaves along main veins, and later in dense colonies on flower stalks, of Impatiens spp. , especially I. parviflora . Most probably originated in Central Asia (Tien Shan), now widely distributed in Europe and Central Asia ( Blackman & Eastop 2023). Monoecious holocyclic on balsams in Europe, with alate males. As noted above, the species was reported from the small balsam in Hungary ( Ripka & Csiszár 2008, Ripka 2011). Those collected at Sopron are illustrated herein ( Figs. 14–17 ). The new specimens were collected both from the small balsam and an undetermined cultivated species. The habitats were less natural than those of the I. balsamines populations. The colonies were not always ant-attended and were of variable size.
