Description of a gynander of Colletes hedini (Hymenoptera: Colletidae) from the Qinghai-Tibetan Plateau, China: the first record of gynandromorphism for the genus after 30 years
Number: 440, Pages: 1 - 12
The first known gynander of the East Asian cellophane bee Colletes hedini Kuhlmann (Hymenoptera: Colletidae) is described and imaged. We provide an illustrated differential diagnosis based on the terminalia, which are entirely male. We also DNA barcoded the gynander to confirm its identity, and the complete barcode sequence is made public. In the single specimen discovered, the distribution of female and male tissues is patchy and random (i.e., not split among tagmata or along a particular axis of the body) and thus the individual can be categorized as a mosaic gynander. This discovery represents one of only a few confirmed cases of gynandromorphism in colletid bees and the second in Colletes.
