Gyrtona oxyptera Hampson, 1912, Cat. Lepid. Phal. Br. Mus. 11: 213.

The colour and markings of the forewing are somewhat reminiscent of those of ferrimissalis, but the wings are narrow, apically acute.
The male genitalia have the valve arms dissimilar in size and shape; the harpe is outcurved, apically asymmetric.
The signum of the female bursa copulatrix is globular, invested with spines to give a stellate structure.
Geographical range
Singapore, Borneo, Sulawesi.
Habitat preference
The species has been taken infrequently in the lowlands, singly at Miri, Sarawak, and Samarinda, Kalimantan, and, in Brunei, once in coastal vegetation at Mumong and three times in dry heath forest at Telisai.
