Helcystogramma bicuneum

Helcystogramma bicuneum is a moth in the Gelechiidae family. It was described by Meyrick in 1911. It is known from north-eastern India and China (Anhui, Guizhou, Hainan, Hong Kong, Hubei, Hunan, Xizang, Yunnan).

The wingspan is 9–10 mm. The forewings are blackish-fuscous with a somewhat arched yellow-ochreous subcostal streak from the base to the disc beyond the middle, edged beneath by a shorter leaden-grey streak not reaching either extremity. There are two oblique white streaks from the costa anteriorly running into the subcostal streak. There is an incurved yellow-ochreous line from one-third of the dorsum to before the apex of the leaden-grey streak, and a fine white S-shaped line from beyond the middle of dorsum to its apex, as well as an oblique leaden-grey line from the middle of the costa to beyond the apex of the subcostal streak, nearly obsolete at the origin, continued as a fine white S-shaped line parallel to the preceding one to the dorsum, between these parallel lines is a yellow-ochreous dot. There is also an oblique white striga from the costa beyond the middle, becoming yellow-ochreous beneath, and two short direct white strigulae from the costa posteriorly. A straight leaden-metallic streak runs from the costa beyond these to the tornus, margined anteriorly below the middle by two wedge-shaped black marks surrounded with yellow-ochreous suffusion, and posteriorly above the middle by a small black spot reaching the termen. The remainder of the terminal area is yellow-ochreous. The hindwings are grey-whitish or whitish-grey in males, darker posteriorly. The hindwings of the females are rather dark grey.
