Abstract: Euonymus maackii is a common ornamental plant in landscaping, which is extensively cultivated in China. Plinachtus bicoloripes Scott (1874) is a common and significant pest attacking Euonymus maackii. The pest mainly feed on leaves and twigs of E. maackii, causing leaf curls and macula. In order to identify the species accurately, clarify the diagnostic characters and update the distribution areas, this study measured and described the features of P. bicoloripes for both adults and nymphs in detail by comparative morphological methods, and relevant photographs were provided for identification.

Key words: Plinachtus bicoloripes Scott,1874; Pest; Morphology; Species identification; Euonymus maackii
