Diagnosis. This species is similar to Lyonetia (Lyonetia) anthemopa, feeding on Pyracantha angustifolia, P. crenulata and Photinia lucida (Rosaceae), but can be distinguished by the following characters. In L. (Lyonetia) prunifoliella, the forewing has an apical pencil from mid of apical transverse line; in the male genitalia, the gnathos apex has three pairs of projections (Fig. 17b); in the female genitalia, the ductus bursae has a ‘T’-shaped sclerotized plate (Figs 22, 22a). In L. (Lyonetia) anthemopa, the forewing has no apical pencil (Kuroko 1964: pl. 1, figs 4a & 4b); the gnathos has two pairs of projections (Kuroko 1964: pl. 8, fig. 44); the ductus bursae has a falciform sclerotized plate (Kuroko 1964: pl. 13, fig. 67).
