Diagnosis. Adult (Figs 7, 8). Wingspan 33–35 mm. Subleuconycta sugii differs from S. calonesiota (Figs 1–4) and S. palshkovi (Figs 5, 6) by its average larger size; the pale brownish-greyish ground colour of forewing; the slightly contrasting, more wavy antemedial and somewhat crenulated postmedial line; the thinner dark line and evenly brown patch between the black outlined orbicular spot and reniform stigmata; the rounded hindwing with slightly wavy postdiscal line. Male genitalia (Figs 17–20). Subleuconycta sugii differs from S. calonesiota (Figs 9–12) and S. palshkovi (Figs 13–16) by its straighter uncus without medial widening; the basally broader subdeltoidal juxta; the more or less evenly curved valvae; the slightly wider corona; the basally widest valvae; the rather rounded apex of valvae (not narrowing); the narrower, tapered saccular processus; the somewhat stronger aedeagus with short coecum; the broader vesica with elongated basal and reduced distal diverticulum. Male 8th abdominal segment (Fig. 23). See the details under S. calonesiota. Female genitalia (Figs 27, 28). Subleuconycta sugii can be distinguished from S. calonesiota (Figs 24, 25) and S. palshkovi (Fig. 26) by its more rounded shape of corpus bursae without signum; the lack of the long, tubelike part of the corpus bursae; the rather quadrangular appendix bursae.
Distribution and bionomics. This species is endemic to Taiwan and distributed in mid-elevation primary broad-leaf forests. The adults occur from Feburary to August, comparatively rarer than S. calonesiota.
