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

(Homoptera: Adelgidae), in Lijiang, Yunnan province, were enumerated, l of which was described as new to science: Scymnus (Pullus) huashansong, and l as new record for China: Adalia conglomerata (L.). Among these 18 species, 14 were also collected from the hemlocks (Tsuga dumosa, T. forrestii, and T. chinensis ) infested with the hemlock woolly adelgid ( Adelges tsugae ).展开更多

The general pattern of parallel benthic and planktonic δ13C shows a decrease trend of δ13C values from the early-middle Miocene to the middle-late Miocene. Two dis tinct δ13C positive excursions at 23.1-22.2 and 17.3-13.6 Ma, and two negative excursions at 10.2-9.4 and 6.9-6.2 Ma have been recognized. All these events are cosmopolitan, providing the good data for the stratigraphic correlation of the South China Sea with the global oceans as well as for studying the changes of the global carbon reservoir and its corresponding climate.展开更多

The Lower Triassic sequences of South China are briefly summarized and the twofold Lower Triassic subdivision is discussed. The type sections of the two Chinese Lower Triassic stages, Yinkengian and Chaohuan, and their definitions are stated.展开更多
