Diagnosis. O. trispinuligera resembles O. trispina in the deeply hooked fore wing apex, and distinctly protruding outer margin on both wings. However, the hollow under the apex is more deeply concave and the outer margin is more protruding in O. trispinuligera . The ground colour of O. trispinuligera is dark brown, but reddish brown and with two colour-forms in O. trispina . The male genitalia are close to those of O. sanguinea and O. liensis by almost oval uncus, not concave medially; the median process of the gnathos is slender and straight; the valva bears small pointed processes. However, in O. trispinuligera three pointed processes are present, with the posterior two longer, and the anterior one shorter; whereas in O. sanguinea and O. liensis , only the anterior two processes are distinct, with the anterior one much longer. In addition, the saccus is much broader in O. trispinuligera than in O. sanguinea and O. liensis . The female genitalia have a spinose signum in the corpus bursae.

Distribution. China (Henan, Shaanxi, Gansu, Hubei, Fujian, Guangxi, Sichuan, Chongqing, Yunnan).

Remarks. The species O. ankyra Chu & Wang, 1991 , which was originally named as O. ancora Chu & Wang, 1987 , a homonym of O. ancora Wilkinson 1972 , was found to be identical to O. trispinuligera on both external and genital characters, and is therefore synonymized here. The anterior process on the valva of O. ankyra ( Fig. 82 ) is present in the preparation shown, but since it overlaps the middle process on both left and right valvae, it is not clearly visible on the figure.
