Diagnosis. This species is distributed in Habahu Nature Reserves and Shapotou Nature Reserves ( Han et al. 2025). In the male genitalia it is similar to A. delicatella , but can be distinguished by the long sacculus about 2/3 the length of the valva and the valva parallel sided. In A. delicatella , the sacculus is about 1/2 the length of the valva, and the valva is narrowed after the sacculus. The female genitalia of A. larissae can be separated from those of A. delicatella by the short ductus bursae, and the large pear-shaped corpus bursae.
