This species has been described from Taiwan by Matsumura (1927) as subspecies Eugoa bipunctata formosicola . Later it was treated as a synonym of Eugoa basipuncta ( Hampson, 1891 ) with question mark by Holloway (2001) and synonym of Eugoa cesaneki Bucsek, 2008 by Bucsek (2016a) . After diagnostic comparison with Eugoa bipunctata ( Walker, 1862 ) from Malaysia ( Figs. 62a, b , 65a, b ), Eugoa basipuncta ( Hampson, 1891 ) from India (see, Kirti & Singh 2016 : 131), Eugoa bipunctata formosicola Matsumura, 1927 from Taiwan ( Figs. 59 , 63a, b ), and Eugoa cesaneki Bucsek, 2008 from Malaysia ( Fig. 60 ), Cambodia ( Figs. 7 , 26 , 45 ) and Japan ( Figs. 61a, b , 64a, b ), established with a valid species, Eugoa formosicola ( Matsumura, 1927 ) n. st. , and Eugoa cesaneki Bucsek, 2008 is n. syn. of formosicola by authors of the present study. Eugoa formosicola ( Matsumura, 1927 ) was reported from Cambodia by Bae et al. (2016) as Eugoa cesaneki Bucsek, 2008 .
