Diagnosis. Ancylosis biculcita can be distinguished by the forewing with a narrower costal band, the long valva apically extended to the middle of the uncus, the conical gnathos with a pointed apex, the anterior margin of the eighth sternum convex in the male genitalia and the elongate sacculate corpus bursae in the female genitalia. The differences of this species from A. leucocephala (Staudinger, 1879) and A. pallida (Staudinger, 1870) have been discussed recently ( Han et al. 2025).

Distribution. China ( Gansu, Hebei, Inner Mongolia, Ningxia, Shaanxi, Tianjin, Xinjiang).
