A preliminary report on butterfly fauna (Insecta: Lepidoptera) of Tengchong Section of Gaoligongshan National Nature Reserve, China

The butterfly fauna of Tengchong Section of Gaoligongshan National Nature Reserve, western Yunnan, China was investigated during a series of field surveys conducted between April 2014 and May 2018. A total of 216 butterfly species were recorded (Hesperiidae 41, Papilionidae 20, Pieridae 21, Lycaenidae 45, and Nymphalidae 89), of which 179 represent new records for Tengchong. Significant findings include paratype materials of a recently described genus and a subspecies, respectively, as well as three national and five provincial new records. Several obscure species were rediscovered during the survey, including two taxa that have not been recorded since their descriptions, Celaenorrhinus morena Evans, 1949 and Thoressa pedla pedla (Evans, 1956). The result of the survey is presented herein with notes on some little-known species. Additionally, past records on Tengchong butterfly fauna were reviewed and a name is treated as nomen nudum.
