FA1A1E692D49FFE4FF4AFE08FA4AFA5A.taxon	diagnosis	Diagnosis. By the wing pattern of this species, it is hardly distinguishable from many congeners of Diduga. The genitalia structure of the new species is similar to D. flavicostata (Snellen), and both species have a large strong spine-like apical structure and a membranous saccular process in the symmetric valva; and the saccus is broadly U-shaped. However, the new species differs from D. flavicostata by having a tapering uncus; and spine-like apical process of valva is strongly sclerotized, weakly waved; apical half of costal margin of valva membranous; and the aedeagus vesica with a large strong spine-shaped cornutus and a bundle of short spines in the male genitalia. In D. flavicostata, uncus is irregularly conic, with a thin hook-shaped apical process; and the apex of valva sclerotized, weakly curved, strongly pointed (spine-like), it is half size of valva length; sclerotized costal margin of valva broadly angled in medial area; and the aedeagus vesica with two slender spine-shaped cornuti (Bayarsaikhan et al. 2023 a: 4, fig. 2 c).	en	Bayarsaikhan, Ulziijargal, Heppner, John B., Kwon, Hyung Wook, Kim, Kil Won, Bae, Yang-Seop (2024): Description of Diduga siamensis sp. nov. and newly recorded D. scalprata (Lepidoptera, Erebidae, Arctiinae) from Thailand, with a checklist of the genus Diduga.
