Forewing infuscate with white stripe broader than in other species, veins yellowish; hind wing with CuA branched. Abdominal apodeme weakly developed (Fig. 36).

Holotype: Male, CHINA, Yunnan Province, Xishuangbanna, 100.90��E, 22.03��N, 8 July 2017, coll. Weijian Huang. Paratype: 2 Male, collect data same as holotype. Notes. The new species is similar to Takagioma silvicola Dworakowska, 1993 in the aedeagus, but can be distinguished from the latter by the relatively thick aedeagal shaft and extremally long pygofer hook. Etymology. The specific epithet is derived from Latin prefix ��� rostr- ���, which refers to the resemblance of the aedeagal shaft apex to the bill of a bird.
