Morphological and cytochrome oxidase 1 (Cox1) data show that Aphis floridanae Tissot (Hemiptera: Aphididae) is not synonymous with A. nasturtii Kaltenbach. Instead, A. floridanae matches the morphological characters of A. impatientis Thomas. Additionally, the range of cytochrome oxidase 1 (Cox1) pair-wise distance of the multiple collections of A. impatientis on Cornus spp., Impatiens spp. and Erechtites hieraciifolius (L.) Raf. ex DC. is 0–0.39%. Therefore, we conclude that A. floridanae Tissot, 1933 is a junior synonym of A. impatientis Thomas, 1878, new synonymy. In addition, A. impatientis is re-described, including first descriptions of the ovipara and alate male of that species.
