On the arrival of the 50th anniversary of Radiocarbon, we review important developments in radiocarbon dating in China during the past 50 years, especially concerning 3 aspects: sample standard and preparation, accelerator mass spectrometry (AMS) facilities, and 14C applications. Specifically, these events are marked by the establishment of the Chinese sucrose charcoal standard in China; the development of small-sample dating in the Xi'an Laboratory of Loess and Quaternary Geology, Chinese Academy of Sciences (CAS); the progress of the AMS facilities in Beijing (China Institute of Atomic Energy and Beijing University); the innovation of the mini-cyclotron-based AMS at Shanghai Institute of Nuclear Research, CAS; the exploration of the Xia-Shang-Zhou chronology project in China; the establishment of the Xi'an multi-element AMS at the Xi'an-AMS Center; and the breakthrough in tracing the geomagnetic intensities and precipitation from 10Be in Chinese loess at the Institute of Earth Environment, CAS.

Spiders of the genus Althepus Thorell, 1898 are found throughout Southeast Asia, notable for their long walking legs. Ten new species are reported in this paper from China, Indonesia, Laos and Myanmar: A.chengmenensis Li & Li, sp. n. (♂♀), A.cheni Li & Li, sp. n. (♂♀), A.gouci Li & Li, sp. n. (♂♀), A.hongguangi Li & Li, sp. n. (♂♀), A.phousalao Li & Li, sp. n. (♂♀), A.qianhuang Li & Li, sp. n. (♂♀), A.qingyuani Li & Li, sp. n. (♀), A.sepakuensis Li & Li, sp. n. (♂♀), A.xuae Li & Li, sp. n. (♂♀) and A.yizhuang Li & Li, sp. n. (♂♀). These species were found in cave entrances and among tree-buttresses, indicating the spiders have a preference for dark and moist environments. All types are deposited in the Institute of Zoology, Chinese Academy of Sciences in Beijing, China (IZCAS).

We present our new graphite target production system, developed in the Institute of Nuclear Research of the Hungarian Academy of Sciences (ATOMKI), for accelerator mass spectrometry (AMS) radiocarbon dating measurements. The system consists of a gas handling line and a graphite target production system. Results of AMS measurements, stable isotope mass spectrometry measurements, and gravimetric/pressure yield determinations have been used to find the proper conditions for the graphitization process. We have also investigated the 14C contamination and the memory effect of the system during the graphitization processes. This paper covers the details of these experiments and a discussion of the results.

The taxonomy of the genus Clytra Laicharting, 1781 occurring in China is studied. Two new species are described: Clytra (Clytraria) tanae sp. nov. from Qinghai and Yunnan, and Clytra (Clytraria) truncatula sp. nov. from Xinjiang. The Chinese fauna of the genus is thus increased to 13 species/subspecies in total. Keys to the Chinese genera of Clytrini and to Chinese species of Clytra are provided in addition to color plates and line drawings of habitus, maxilla, labium, male genitalia and spermatheca, which facilitates species identification; geographic distributions of 12 species/subspecies are mapped. The type specimens are deposited in Institute of Zoology, Chinese Academy of Sciences, Beijing, China.
