We report the first record of the beetle tribe Xylographellini (Ciidae) from the continental Palaearctic Region, represented by five new species discovered in Yunnan and Sichuan provinces, China: Scolytocis danae sp. nov., Syncosmetus euryale sp. nov., Sync. medusa sp. nov., Sync. perseus sp. nov. and Sync. stheno sp. nov. Illustrations and identification keys are provided for these new species...

Climate change is negatively affecting the coffee value chain, with a direct effect on approximately 100 million people from 80 countries. This has been attributed to high vulnerability of two-mainstream species, Coffea arabica and canephora, extreme weather events, notable uneven increases in market prices. Taking into account narrow genetic plasticity commercial cultivars, wild-relatives unde...

Phytochemical analysis of the rhizomes of Cimicifuga racemosa (Ranunculaceae) resulted in the isolation of twelve cycloartane glycosides (1--12), including four new ones (4--6, 12). The structures of the new compounds were determined by spectroscopic analysis, including two-dimensional (2D) NMR data, and chemical methods. The isolated compounds were evaluated for their cytotoxic activities agai...
