First report of an intersex individual of the click beetle Pectocera fortunei (Elateridae) and additional cases of gynandromorphism in Coleoptera (Lucanidae, Scarabaeidae)

This study documents the first case of an intersex individual of <i>Pectocerafortunei</i> Candèze, 1873, from the Korean Peninsula, including behavioural findings. This is the first report of such a phenomenon in the family Elateridae. Two cases of gynandromorphism are also described: one in <i>Dorcustitanuscastanicolor</i> (Motschulsky, 1861) (Lucanidae) and the other in <i>Trypoxylusdichotomusseptentrionalis</i> (Kôno, 1931) (Scarabaeidae). The former is a new record for this subspecies. An updated list of intersex and gynandromorphic beetles is also provided.
