The Real Status of Chlorogomphus splendidus (Selys, 1878) in Taiwan (Odonata: Chlorogomphidae)

The single record of Chlorogomphus splendidus (Selys, 1878) in Taiwan was based on a single female specimen collected from Lanyu Island in eastern Taiwan. The status of this species in Taiwan has remained uncertain for nearly a century, as no new material is available for study. Upon the capture of a female C. risi Chen, 1950 in 2010 from the island, we decided to re-examine the voucher specimen of C. splendidus and compared it with the female C. risi. The result reveals that Lanyu C. splendidus is a pale-winged female C. risi. Hence, Chlorogomphus splendidus has to be excluded from the list of Taiwanese Odonata.
