Remarks. (1) In the original female genitalia illustration of A. lichenshihi ( Wu & Kishida 2020: fig. 18), the authors erroneously provided a photo of an unidentified species of the genus Nephelomilta Hampson, 1900 most similar to Nephelomilta karenkonis (illustrated by Volynkin & Černý 2018: fig. 140). (2) In the original diagnosis ( Wu & Kishida 2020), the species was compared with the genitally rather dissimilar A. aberrans and not the closely related A. dingjiai ( Figs 7, 8 , 12 , 16 ) described recently from Lanyu Island ( Hsu et al. 2018). The comparison with the latter is provided below.

Diagnosis. Aberrasine lichenshihi is similar externally to A. aberrans (illustrated by Volynkin et al. 2019b and Wu & Kishida 2020) and A. peraffinis (illustrated by Volynkin 2018), but differs from the former one by its slightly more reddish forewing coloration and the posterior part of the medial line curved closer to the antemedial line (in A. aberrans , the area between the lines is markedly wider), and from the latter one by the antemedial line more strongly angular in the cell and the sinuous medial line (it is nearly straight in A. peraffinis ). The male genitalia of A. lichenshihi are very similar to those of A. dingjiai which has clearly different forewing pattern. The male genital capsule of A. lichenshihi differs from that of A. dingjiai by the longer and wider distal section of costa which is more strongly curved dorsad, and the somewhat larger ventral plate of the costa. The aedeagus of A. lichenshihi is conspicuously smaller than that of A. dingjiai . Compared to that of A. dingjiai , the vesica of A. lichenshihi is narrower and slightly shorter, the elongate cluster consists of thinner but more numerous spines, and the smaller cluster of spines is wider. In the female genitalia of A. lichenshihi , the ductus bursae is wider and somewhat narrower, the corpus bursae is longer and the sclerotized area of its posterior end is wider than in A. dingjiai . Additionally, the appendix bursae of A. lichenshihi is slightly longer than in A. dingjiai and covered in more numerous but smaller spinules.

Distribution. The species is endemic to Taiwan Island.
