When audiences applaud an acrobat's bril-liant performance, they have no idea of the hardship that goes into its preparation. Mindful of their personal safety, acrobats take a serious and conscientious attitude to daily training, and accept unquestion-ingly the (literally) blood, sweat, and tears it entails.展开更多

These are: Calodia bifurcata sp. n. from Guizhou and Calodia bispinosa Nielson from Yunnan. They bring the total number to 58 known species in the genus now, of which 21 species are distributed over China.展开更多
