Remarks: The genus and species name ‘† Paralycoptera wui ’ first appeared in a brief report ( Chang & Chou, 1974), but no description and illustrations were provided. It was not until 1977 that the original description was published ( Chang & Chou, 1977).

Thus, † P. wui was considered to be formally established in Chang & Chou (1977).

Emended diagnosis: As genus, monotypic. D. II+10, P. I+8, V. 7, A. III+18, C. I+8/7+I.
