The powder post beetles (Coleoptera: Bostrichidae) (except Lyctinae) of Yunnan Province in Southwest China are reviewed for the first time. Keys to twenty-six genera and fifty-two species from the Yunnan region are provided. One new genus and seven new species are described: Dinoderus (Dinoderastes) hongheensis sp. nov., Dinoderus (Dinoderastes) nanxiheensis sp. nov., Gracilenta yingjiangensis gen. nov., sp. nov., Calonistes vittatus sp. nov., Calophagus colombiana sp. nov., Xylodrypta guochuanii sp. nov. and Xylodrypta zhenghei sp. nov.. Fourteen species are recorded in China for the first time. The bostrichid fauna of Yunnan is compared with those of the neighbouring bio-geographically related Southeast Asian and Himalayan regions. The fauna has a close affinity with that of tropical Southeast Asia and a much weaker relationship with the Palearctic region. The differences with the Himalayas may reflect the separate evolutionary and complex geological history of the two areas.
The origins of the Cold War in Southeast Asia are most often located in the immediate aftermath of the Second World War, in the late 1940s. Historians sometimes trace its origins to Japan's expansionist phase in the 1930s, which accelerated the decline of the European and American colonial order in this part of Asia. However, the necessity of the fight against communism appeared very clearly in the minds of the leaders of the major colonial powers well before the 1930s. Focused on the case of Siam, this article aims to show that the origins of the Cold War in Southeast Asia dated back to as early as the 1920s with the emergence of international cooperation in the fight against communism and the Thai elite's manipulation of imperialist powers to further their own political agenda and support their dominance in the domestic political arena. The Cold War in Southeast Asia was not only about the postwar fight against the spread of communism, but also closely intertwined with the decolonisation and nation-building efforts of every country in the region — including of the so-called un-colonised Thailand.
