Cotoneaster cochleatus was treated as a variety of C. microphyllus by L. Lingdi and A. R. Brach (2003); here the two are distinguished at species rank, following H. Nybom et al. (2005). Plants of C. microphyllus have a suberect habit, usually elliptic leaves (rarely broadly obovate) with acute apices, and pomes 6 mm wide; C. cochleatus is always prostrate and has usually obovate leaves (rarely suborbiculate) with blunt apices, and pomes 8–10 mm wide.
