Thliptoceras formosanum Munroe & Mutuura, 1968: 861 . Type locality: China, Taiwan, Urai.

DIagnosIs. Wing expanse 18–24 mm. Thliptoceras formosanum has the narrow, modified wings of the artatalis group in the male, of dark, greyish fuscous colour, and somewhat paler, more yellowish in the female. It is characterized by a strongly modified male antenna: scape enlarged, base of flagellum enlarged and complex, with large, dorsal fan-shaped scale tuft arranged in a semicircle dorsally of a small depression bordered by two triangular teeth and filled with very small setae, next few segments strongly widened and compressed, curved to form a large shallow sinus. In the male genitalia, this species can be recognized by the claw-shaped sacculus process and the gently concave costa without excavation or spine. In the female genitalia, the weakly sclerotized posterior part of the ductus bursae with an ovate expansion at its base is diagnostic.
