 Diagnosis. Dark greenish Impatientinum with mostly pale, striped legs, black siphunculi and pale cauda. Aptera with height of antennal tubercles about 0.3 × length of first antennal segment; secondary rhinaria on antennal segments: III 6–9, IV 3–4, V 3–4; siphunculi with reticulation on the apical fifth, length 0.8 of head width across eyes; cauda with rounded apex; antennal PT/BASE 4.1–4.5.   
 Distribution and ecology. Usually forms small colonies on undersides of leaves of Impatiens spp., most common on I. noli-tangere. Most probably of east Asian origin, now widely distributed in Europe and Asia. Monoecious holocyclic with alate males. There are several monophagous aphids known from touch-me-not species, but in Hungary, only Impatientinum asiaticum Nevsky, 1929 was reported from the small balsam, together with the polyphagous Aphis (Aphis) fabae Scopoli, 1763 (Ripka & Csiszár 2008, Ripka 2011). The latter species was noted from unspecified Impatiens species as well (Szalay-Marzsó 1989, Basky 2005). The Hungarian specimens of I. balsamines were mostly collected from the invasive alien small balsam (I. parviflora DC.) and was found only once from the native touch-me-not balsam (I. noli-tangere L.), despite that in Europe the species usually spread on the touch-me-not balsam (Blackman & Eastop 2023). The habitats were mostly natural forests where the weed spread along forest roads. The colonies were not always ant attended and of a rather variable size, mostly on the inflorescence and the upper stem. The colonies contained both alatae and apterae forms during the whole summer.
