Ten species of Podagricomela Heikertinger from China are studied. They are Podagricomela apicipennis (Jacoby), P. cupera Wang, P. cyanea Chen, P. flavitibialis Wang, P. geminata Chen et Zia, P. nigricollis Chen, P. ni...Ten species of Podagricomela Heikertinger from China are studied. They are Podagricomela apicipennis (Jacoby), P. cupera Wang, P. cyanea Chen, P. flavitibialis Wang, P. geminata Chen et Zia, P. nigricollis Chen, P. nigripes Medvedev, P. parva Chen et Zia, P. shirahatai (Ch?j?), and P. weisei Heikertinger. Among them, P. nigripes Medvedev is recorded for the first time from China. A key to species from China is given. Illustrations of the male aedeagus and female spermatheca of each species are also given. The geographical distribution in China is analyzed briefly. The result indicates that Podagricomela mainly occurs in southern China, southwestern China, central China and north China, and the distribution center of this genus is in China. They always feed on Rutaceae.展开更多
